This document explains Naturem’s information security requirements for all employees.

Naturem’s management has committed to these policies to protect information utilized by

Naturem in attaining its business goals. All employees are required to adhere to the policies described within this document.

The Payment Card Industry Data Security Standard (PCI DSS) Program is a mandated set of security standards that were created by the major credit card companies to offer merchants and service providers a complete, unified approach to safeguarding credit cardholder information for all credit card brands.

In September of 2006, a group of five leading payment brands including American Express,

Discover Financial Services, JCB, MasterCard Worldwide and Visa International jointly announced formation of the PCI Security Standards Council, an independent council established to manage ongoing evolution of the PCI standard. Concurrent with the announcement, the council released version 1.1 of the PCI standard.

PCI DSS requirements apply to organizations where account data (cardholder data and/or sensitive authentication data) is stored, processed or transmitted. Some PCI DSS requirements may also be applicable to organizations that have outsourced their payment operations or management of their Cardholder Data Environment (CDE). Additionally, organizations that outsource their CDE or payment operations to third parties are responsible for ensuring that the account data is protected by the third party per the applicable PCI DSS requirements.

During normal course of compliance and reporting activities Naturem will ensure that proper scoping of compliant PCI operations and reporting are in effect.

This Information Security Policy applies to all system components included in or connected to the cardholder data environment. The cardholder data environment (CDE) is comprised of people, processes and technologies that store, process, or transmit cardholder data or sensitive authentication data. “System components” include network devices, servers, computing devices, and applications. Examples of system components include but are not limited to the following:

  • Systems that provide security services (for example, authentication servers), facilitate segmentation (for example, internal firewalls), or may impact the security of (for example, name resolution or web redirection servers) the CDE.
  • Virtualization components such as virtual machines, virtual switches/routers, virtual appliances, virtual applications/desktops, and hypervisors.
  • Network components including but not limited to firewalls, switches, routers, wireless access points, network appliances, and other security appliances.
  • Server types including but not limited to web, application, database, authentication, mail, proxy, Network Time Protocol (NTP), and Domain Name System (DNS).
  • Applications including all purchased and custom applications, including internal and external (for example, Internet) applications.
  • Any other component or device located within or connected to the CDE.
  • Support systems (e.g. Active Directory, PC’s performing support functions such as system administration, etc)

12.6.2 Require personnel to acknowledge at least annually that they have read and understood the security policy and procedures.

All proposed changes to Naturem network devices, systems and application configurations must follow this policy.

The responsible party that will be implementing the change must complete and submit a

Change Request Form to the COO. A model form is shown in Appendix C illustrating the minimum data to be captured electronically or on hard copy. This form will not be reviewed without the following information completed, at a minimum:

  • Resources Affected by Change (customers) – If a change could impact the functionality of customers, internal or external, this item must be completed. This documentation must include changes to features, applications and procedures that will be different from the existing system. Included in this documentation are any upgrades that the customer needs to perform to the operating system or other required 3rd party software or hardware.
  • Back out Procedures – If the change does not go as intended a plan must be in place that describes the process of reverting the environment to its original configuration.
  • Test Plan – A set of planned tests must be developed to verify that the change accomplished what it was supposed to do, and does not adversely affect other system components or create a weakness in the security posture of the environment. This plan may be specific to each change.

Completion of the relevant details in the Naturem issue tracking system is equivalent to completion of the change request form.

PCI Requirements Reference:

Audit Procedure 6.4.5.1 Verify that documentation of customer impact is included in the change control documentation for each sampled change

Audit Procedure 6.4.5.4 Verify that back-out procedures are prepared for each sampled change.

After all planning and documentation is complete all management and concerned parties must signoff on the Change Request Form.

This can be achieved verbally in the weekly IT Development meeting.

PCI Requirements Reference:

Audit Procedure 6.4.5.2 Verify that documented approval by authorized parties is present for each sampled change.

Prior to introduction into the production network or systems all changes must first be tested on a QA or test network isolated from the production environment.

The documented test plan must be followed to ensure no adverse security effects on the network, systems or applications. Any discrepancies should be documented and a new Change Request Form generated once all issues have been resolved.

PCI Requirements Reference:

Audit Procedure 6.4.5.3.a Verify that functionality testing is performed to verify that the change does not adversely impact the security of the system.

Audit Procedure 6.4.5.3.b For custom code changes, verify that all updates are tested for compliance with PCI DSS Requirement 6.5 before being deployed into production.

All changes must be implemented according to the documented change procedures that were tested successfully. Any discrepancies between expected results and actual results that impact the network, systems, applications, business requirements or support procedures must result in the immediate invocation of the documented back out procedures.

All data stored and accessed on Naturem information systems, whether managed by employees or by a third party, must follow this policy. Policy exemptions will be permitted only if approved in advance and in writing by the COO.

All data stored on Naturem computing resources must be assigned a classification level by the information owner or creator. This level is used to determine which users are permitted to access the data.

  • Naturem Internal Information Categories

Confidential – applies to the most sensitive business information which is intended strictly for use within Naturem. Unauthorized disclosure could seriously and adversely impact the company, stockholders, business partners, and/or its customers.

Confidential information includes:

  • Passwords
  • Encryption keys
  • Cardholder information
  • Bank account information
  • Intellectual property

Sensitive – Applies to less sensitive business information which is intended for use within Naturem. Unauthorized disclosure could adversely impact the company, its stockholders, its business partners, and/or its customers.

Sensitive information includes:

  • Internal market research
  • Audit reports, etc.

Private – Applies to personal information which is intended for use within Naturem.

  • Unauthorized disclosure could adversely impact the company and/or its employees.
  • Examples of Private information include: policies and procedures, procedure metrics, human resources information, etc

Public – Applies to all other information which does not clearly fit into any of the above three classifications. Unauthorized disclosure isn’t expected to seriously or adversely impact the company. Any release of this information must be authorized by the COO or CEO.

Public information includes:

PCI Data – The class of credit card and transaction data identified for protection under the Payment Card Industry (PCI) Data Security Standard (DSS). These data are specified in the Requirements and Security Assessment Procedures (RSAP) Version 2.0. 2 types of data are defined: Cardholder Data which may be stored after transaction authorization and Sensitive Authentication Data which may not be stored after transaction authorization.

  • Card Holder Data – Applies to credit card data taken as payment for services. Data elements as specified in the PCI Security Audit Procedures version 1.1 are
    • Primary Account Number (PAN)
    • Card holder Name
    • Service Code
    • Expiration Date
  • Sensitive Authentication Data – Applies to credit card data required for authentication and processing of credit card transactions as specified in the
    • PCI Requirements and Security Assessment Procedures 2.0 are
    • Full Magnetic Stripe
    • CVC2/CVV2/CID
    • PIN/PIN Block

All confidential or sensitive data must be protected via access controls to ensure that data is not improperly disclosed, modified, deleted or rendered unavailable. The access controls must track all access to such data and identify who and when the data was accessed (See Section 15 Logging Controls Policy for more details). All access to systems must be configured to deny-all but what information a particular user needs to access per their business role.

Access to systems or applications handling confidential, sensitive or private information must follow the data access request process. All requests require approval by the Information Security Team and a valid Authorization Request Form (Appendix B – A model form is shown illustrating the minimum data to be captured electronically or on hard copy. Access to data exceeding the employee’s authorized role must also follow the data access request process and must include documented limits around such access (e.g. access source, access time limits, etc). All access creation, modification and deletion request records must be retained for a period of 6 months following access termination.

  • Data Access Request Process

The following generally describes the workflow used by Naturem for requesting new access:

  1. The user’s manager will request or grant (as appropriate) authorization for access to confidential data via the New Employee Card (Appendix P).
  2. The user’s manager must approve the request for access based on the employee’s role, identify any additional access requirements and submit the request to a member of the Information Security Team for approval.
  3. If the access requested requires privileges above the employee’s role a member of the Information Security Team will engage additional system owners or management to confirm.
  4. The Information Security Team will forward the approved request to the System Administrator for account creation.
  5. The System Administrator will create the user account(s) requested. Once the accounts have been created, the System Administrator must forward the request form to the COO for inclusion in the Users employee records and notify the Information Security Team that the request has been completed.

Requests for change of access must be submitted by the user’s manager utilizing the last version of the New Employee Card (Appendix P). Business units are expected to capture this data in such a form that a clear audit trail is available for review at all times on file and the workflow shall be the same as above.

Direction regarding removal of an employee’s access shall follow the same workflow above.  When an employee leaves the business a note will be added to their New Employee Card to confirm that access has been removed.

PCI Requirements Reference:

7.1 Limit access to system components and cardholder data to only those individuals whose job requires such access.

Hard copy materials and electronic media containing sensitive or confidential information must be protected by appropriate physical access controls.

  • Cameras must be used to monitor server closets and data centers where systems reside that store sensitive, confidential, and cardholder data. The data collected must be stored for at least 3 months unless otherwise restricted by law.
  • Appropriate facility controls must be used to limit and monitor physical access to systems that store confidential or sensitive data.
  • Visitor logs and physical audit trails of access to these systems must be collected and kept at least 3 months unless otherwise restricted by law.
  • Physical access must be restricted to publicly accessible network jacks, wireless access points and handheld devices.

PCI Requirements Reference:

9.1 Use appropriate facility entry controls to limit and monitor physical access to systems in the cardholder data environment.

9.1.1 Use either video cameras or access control mechanisms (or both) to monitor individual physical access to sensitive areas. Review collected data and correlate with other entries. Store for at least three months, unless otherwise restricted by law.

9.1.2 Implement physical and/or logical controls to restrict access to publicly accessible network jacks.

9.1.3 Restrict physical access to wireless access points, gateways, handheld devices, networking/communications hardware, and telecommunication lines.

Each user’s access privileges shall be authorized according to business need. User access authority to computer resources shall be provided only when necessary to perform tasks related to Naturem business.

The use of non-authenticated (e.g., no password) User IDs or User IDs not associated with a single identified user are prohibited. Shared or group user IDs are never permitted for user-level access. Every user must use a unique user account and a personal secret password for access to Naturem information systems and networks. Systems and applications must authenticate using a password or token entry.

All users must acknowledge understanding of the Naturem Information Security Policies by reading and signing the Naturem Security Acknowledgment and Acceptable Use Policy (Appendix A) prior to being allowed to access Naturem information systems and networks.

PCI Requirements Reference:

7.2 Establish an access control system(s) for systems components that restricts access based on a user’s need to know, and is set to “deny all” unless specifically allowed.

8.1 Define and implement policies and procedures to ensure proper user identification management for non-consumer users and administrators on all system components as follows:

8.1.1 Assign all users a unique ID before allowing them to access system components or cardholder data.

8.1.2 Control addition, deletion, and modification of user IDs, credentials, and other identifier objects.

8.1.3 Immediately revoke access for any terminated users.

8.1.4 Remove/disable inactive user accounts within 90 days.

8.1.5 Manage IDs used by third parties to access, support, or maintain system components via remote access as follows:

–     Enabled only during the time period needed and disabled when not in use.

–     Monitored when in use.

8.1.6 Limit repeated access attempts by locking out the user ID after not more than six attempts.

8.1.7 Set the lockout duration to a minimum of 30 minutes or until an administrator enables the user ID.

8.1.8 If a session has been idle for more than 15 minutes, require the user to re-authenticate to re-activate the terminal or session.

8.4 Document and communicate authentication policies and procedures to all users including:

–   Guidance on selecting strong authentication credentials

–   Guidance for how users should protect their authentication credentials

–   Instructions not to reuse previously used passwords

–   Instructions to change passwords if there is any suspicion the password could be compromised.

8.7 All access to any database containing cardholder data (including access by applications, administrators, and all other users) is restricted as follows:

–   All user access to, user queries of, and user actions on databases are through programmatic methods.

–   Only database administrators have the ability to directly access or query databases.

–   Application IDs for database applications can only be used by the applications (and not by individual users or other non-application processes).

10.1 Implement audit trails to link all access to system components to each individual user.

  • Systems Access Controls

Each computer system shall have an automated or procedural access control process. The process must:

  • The user ID shall consist of at least 7 characters.
  • User ID’s will be unique for each user
  • Authenticate every user ID, system account and application account with a password.
  • Require all passwords to be at least 7 characters in length.
  • Require complex passwords, consisting of numeric, alphabetic & special characters with a mixture of both upper and lower case ones.
  • Require that new passwords cannot be the same as the four previously used passwords.
  • Lock out accounts after not more than six invalid logon attempts.
  • Require that once a user account is locked out it remains locked for a minimum of 30 minutes or until the System Administrator resets the account.
  • Require system/session idle time out of 15 minutes.
  • Require passwords to be reset at least every ninety (90) days. Note: Job/Service user IDs may be exempt from this requirement with management approval. Administrative user ID’s (e.g. root, Oracle, Administrator) must comply.
  • Remove or disable inactive user accounts over 90 days old.
  • Educate employees as part of induction and awareness programs & require the use of company approved password vault utilities to prevent disclosure of written password.
  • Authentication credentials such as passwords must be protected from eavesdropping when transmitted over both trusted and untrusted networks (i.e. internal and external ones) by means of implementing industry approved encryption or hashing algorithms.
  • Authentication credentials must be protected from disclosure/theft when stored by implementing industry approved encryption or hashing algorithms. These requirements apply to both internally developed or 3rd party applications, operating systems, devices or solutions.

The requirements above are for authenticating all system users.

PCI Requirements Reference:

8.1 Define and implement policies and procedures to ensure proper user identification management for non-consumer users and administrators on all system components as follows:

8.1.1 Assign all users a unique ID before allowing them to access system components or cardholder data.

8.1.2 Control addition, deletion, and modification of user IDs, credentials, and other identifier objects.

8.1.3 Immediately revoke access for any terminated users.

8.1.4 Remove/disable inactive user accounts within 90 days.

8.1.5 Manage IDs used by third parties to access, support, or maintain system components via remote access as follows:

–   Enabled only during the time period needed and disabled when not in use.

–   Monitored when in use.

8.1.6 Limit repeated access attempts by locking out the user ID after not more than six attempts.

8.1.7 Set the lockout duration to a minimum of 30 minutes or until an administrator enables the user ID.

8.1.8 If a session has been idle for more than 15 minutes, require the user to re-authenticate to re-activate the terminal or session.

The Information Security Team will approve access authorization according to the role and responsibilities of information system users. Each request for access must contain written and/or electronic evidence of approval by the Information Security Team.

Information Security, in conjunction with business unit management, will determine the default access levels that will be granted per a user’s role. The Information Security Team will perform a bi-annual audit of computer resource authorizations to confirm that access privileges are appropriate. The audit will consist of validating access rights for sample user populations.

The Information Security Team must collect additional approvals for all access that is not associated with a defined access role. Extension authorizations for contractor accounts must go through the Information Security Team to provide an audit trail. An Emergency ID will be established when access is needed to diagnose and/or correct a problem.

  • The request to create the Emergency ID must be made via the Information Security Team which will notify the appropriate system administration team.
  • The requestor must inform the Information Security Team upon completion of the work so that the ID can be disabled.
  • The Information Security Team will ensure that the Emergency ID Request Form is completed as soon as practical (the completion of this form should NOT delay providing access). The completed form must be filed by the Information Security Team
  • System Administrator Responsibilities

Account creation requests must specify access either explicitly or via a “role” that has been mapped to the required access. New accounts created by mirroring existing user accounts must be audited against the explicit request or roles for appropriate access rights. If a user requests a password reset via phone, email, web or other non-face-to-face method, that user’s identity must be verified before the password is reset Either through a request filed by his line manager or by presenting him/herself to the relevant system administrator.

Access should be removed immediately upon notification that access is no longer required.

Written procedures must be in place to ensure that access privileges of terminated or transferred users are revoked as soon as possible. Whenever possible users who are on leave-of-absence or extended disability should be suspended from the system.

User IDs shall be disabled after sixty (60) days of inactivity. After an additional thirty (30) days, disabled user IDs must be purged. These requirements may not apply to certain specialized accounts (e.g., NT Admin, root). In those instances, the System Administrator must provide a written waiver to the Information Security Team and document the compensating controls around access to the accounts.

  • System Administrator
  • Assure that changes to firewall hardware or software or security rules are approved by the Information Security Team and follow all change control policies and procedures.
  • Document all firewall security rule changes utilizing Appendix E, Permitted Network Services and Protocols (A model form is shown illustrating the minimum data to be captured electronically or on hard copy).
  • Following every change, review and update network diagrams to assure they accurately describe all connections to confidential or sensitive information and critical network protection mechanisms (e.g., firewalls, IDS/IPS, Anti-virus systems, access control systems, etc.).
  • Enable appropriate logging on all security systems and perform active daily monitoring of the logs that report security events.
  • Provide the Network Operations Center with read-only access to logs related to the critical systems health and performance.
  • Provide the Network Operations Center and Information Security Team with read-only access to security event logs.
  • Report network security incidents to the Information Security Team immediately upon discovery.
  • Coordinate an appropriate response with the Information Security Team to mitigate security events.
  • Ensure that router configuration files are secured and synchronized properly.
  • Network Operations Center
  • Monitor system and application specific alerts on critical systems (e.g., interface up/down, firewall daemon failing, system reboots, etc.)
  • Notify the appropriate parties in the event of a security system failure or security event.
  • Information Security Team
  • Assure that security rules applied to the firewalls are sufficient to protect Naturem networks and corporate assets from external attacks and unauthorized access.
  • Assure that security rules applied to the firewalls are sufficient to prevent internal security events from leaving the Naturem network.
  • Review all firewall and router security rule change requests for policy compliance prior to submission through the change management process.
  • Ensure that all protocols/services allowed through the firewalls are properly documented
  • Avoid the usage of risky protocols. If business or technological constraints justify their use, ensure the risky protocol employed has undergone a risk assessment which specifies compensating controls as well as documents the identified constraints.
  • Actively monitor firewall security events to identify internal or external security incidents.
  • Coordinate an appropriate response with the System Administrator to mitigate security events.

PCI Requirements Reference:

1.1.2 Current network diagram that identifies all connections between the cardholder data environment and other networks, including any wireless networks.

1.1.4.a Examine the firewall configuration standards and verify that they include requirements for a firewall at each Internet connection and between any DMZ and the internal network zone.

1.1.4.b Verify that the current network diagram is consistent with the firewall configuration standards.

1.1.4.c Observe network configurations to verify that a firewall is in place at each Internet connection and between any demilitarized zone (DMZ) and the internal network zone, per the documented configuration standards and network diagrams.

1.2.2 Securing and synchronizing router configuration files. For example, running configuration files (for normal functioning of the routers), and start-up configuration files (when machines are re-booted) should have the same secure configuration

Because firewalls support critical Naturem information systems activities they are considered to be production systems.

All firewall changes must be approved by the Information Security Team and must be adequately tested following production standards as defined in the Change Control Policy.

These changes include, but are not limited to:

  • Firewall rule additions, deletions, and modifications.
  • Firewall or router software or system modifications.
  • Firewall or router software or system upgrades, patches, or hot-fixes.

PCI Requirements Reference:

1.1.1 Inspect the firewall and router configuration standards and other documentation specified below and verify that standards are complete and implemented as follows:

1.1.1.a Examine documented procedures to verify there is a formal process for testing and approval of all:

–   Network connections and

–   Changes to firewall and router configurations

1.1.1.b For a sample of network connections, interview responsible personnel and examine records to verify that network connections were approved and tested.

1.1.1.c Identify a sample of actual changes made to firewall and router configurations, compare to the change records, and interview responsible personnel to verify the changes were approved and tested.

Every connectivity path and service that is not specifically permitted by this policy, with supporting documents issued by the Information Security Team, must be blocked by Naturem firewalls. The list of currently approved paths and services, with justifications, is listed in Appendix E, Permitted Network Services and Protocols.

PCI Requirements Reference:

1.1.6.a Verify that firewall and router configuration standards include a documented list of all services, protocols and ports, including business justification and approval for each.

1.1.6.b Identify insecure services, protocols, and ports allowed; and verify that security features are documented for each service.

1.1.6.c Examine firewall and router configurations to verify that the documented security features are implemented for each insecure service, protocol, and port.

1.2 Build firewall and router configurations that restrict connections between untrusted networks and any system components in the cardholder data environment.

1.2.1 Restrict inbound and outbound traffic to that which is necessary for the cardholder data environment, and specifically deny all other traffic.

All Internet-based inbound traffic is only permitted into a firewall segmented demilitarized zone (DMZ) network. In all cases, this traffic should be limited to only ports necessary for Naturem’s business requirements. Perimeter routers should not be configured with a route to internal address space with the exception of the DMZ. Internal IP addresses must be hidden utilizing Network Address Translation (NAT) or Port Address Translation (PAT). Anti-spoofing technologies must be configured on perimeter devices, denying or rejecting all traffic with a:

  • Source IP address matching internally allocated or Naturem owned address space.
  • Source IP address matching RFC 1918 address space.
  • Destination IP address matching RFC 1918 address space.

Outbound traffic from internal production systems must only be allowed to the Naturem DMZ network. Additionally, this traffic should be restricted to only required protocols and services.

Databases must be located on an internal network which is segmented from the Naturem DMZ network. Inbound connections to internal production payment systems, and originating from Naturem wireless networks, are not permitted. The use of a stateful packet inspection firewall must be utilized for Internet and wireless segmentation to only allow established connections into or out of each particular network segment. VLAN’s with compliant ACL’s may be used for cardholder environment segmentation so long as the VLAN switch is compliant with PCI and hardened to prevent all currently identified switch exploits (e.g. ARP cache flood). If VLAN’s are used for segmenting all requirements for firewalls apply (e.g. deny all but business necessary traffic, change control, etc).

PCI Requirements Reference:

1.1.4 Requirements for a firewall at each Internet connection and between any demilitarized zone (DMZ) and the internal network zone

1.3 Prohibit direct public access between the Internet and any system component in the cardholder data environment.

1.3.1 Implement a DMZ to limit inbound traffic to only system components that provide authorized publicly accessible services, protocols, and ports.

1.3.2 Limit inbound Internet traffic to IP addresses within the DMZ.

1.3.3 Implement anti-spoofing measures to detect and block forged source IP addresses from entering the network. (For example, block traffic originating from the Internet with an internal source address.)

1.3.4 Do not allow unauthorized outbound traffic from the cardholder data environment to the Internet.

1.3.5 Permit only “established” connections into the network.

1.3.6 Place system components that store cardholder data (such as a database) in an internal network zone, segregated from the DMZ and other untrusted networks.

1.3.7 Do not disclose private IP addresses and routing information to unauthorized parties. Note: Methods to obscure IP addressing may include, but are not limited to:

–   Network Address Translation (NAT)

–   Placing servers containing cardholder data behind proxy servers/firewalls

–   Removal or filtering of route advertisements for private networks that employ registered addressing

–   Internal use of RFC1918 address space instead of registered addresses.

At least quarterly, the Information Security Team must thoroughly review each firewall rule set and record results of the review. The review must include the removal, when merited, of unused or unnecessary access paths. All proposed changes identified as a result of this review must go through the current change control process prior to implementation.

PCI Requirements Reference:

1.1.7 Requirement to review firewall and router rule sets at least every six months.

All mobile and/or employee-owned computers with direct connectivity to the Internet (e.g., laptops used by employees) that are used to access the Naturem network must have personal firewall software installed and activated. All such software must have a non-user alterable configuration as dictated by the Information Security Team.

PCI Requirements Reference:

1.4 Install personal firewall software or equivalent functionality on any portable computing devices (including company and/or employee-owned) that connect to the Internet when outside the network (for example, laptops used by employees), and which are also used to access the CDE. Firewall (or equivalent) configurations include:

–   Specific configuration settings are defined.

–   Personal firewall (or equivalent functionality) is actively running.

–   Personal firewall (or equivalent functionality) is not alterable by users of the portable computing devices.

All servers and network devices on Naturem networks, whether managed by employees or by third parties, must be built and deployed in accordance with this policy. Exemptions from this policy will be permitted only if approved in advance and in writing by the Chief Technical Officer.

All computing systems should be designated for a single primary purpose where possible

(e.g., web servers, database servers, and DNS should be implemented on separate servers). No multi-purpose systems may, under any circumstances, store, transmit, or process confidential or sensitive data unless required by vendor documentation (e.g., SAP, Peoplesoft, ipAngel, Cisco Pix with add-ons, etc).

PCI Requirements Reference:

2.2.1 Implement only one primary function per server to prevent functions that require different security levels from co-existing on the same server. (For example, web servers, database servers, and DNS should be implemented on separate servers.)

Note: Where virtualization technologies are in use, implement only one primary function per virtual system component.

  • System Configuration Standards

All systems, prior to deployment in the production environment must conform to the

System Configuration Standards (Appendix G- a model form is shown illustrating the minimum data to be captured electronically or on hard copy).

Critical files are usually those that do not regularly change, but the modification of which could indicate a system compromise or risk of compromise. File-integrity monitoring products usually come pre-configured with critical files for the related operating system. Other critical files, such as those for custom applications, must be evaluated and defined by the entity (that is, the merchant or service provider).

  • Standard Software

The following list must be considered standard installed software on all applicable systems. A valid business justification and risk assessment must exist for all deviations from Naturem published configuration standards. Any such deviations require written approval by the Information Security Team, and noted on the System Configuration Record for the system (see below).

If the application is designed for a specific purpose in which the full credit card number must be displayed approval must be given by the Information Security Team during the Requirements Phase as described in section 12 Software Development Policy. In all cases displaying full or masked card numbers must be limited to the fewest number of users possible.

PCI Requirements Reference:

3.3 Mask PAN when displayed (the first six and last four digits are the maximum number of digits to be displayed), such that only personnel with a legitimate business need can see more than the first six/last four digits of the PAN.

  • Credit Card Storage Applications

All Naturem applications, dealing with the storage of cardholder information, must be configured in a manner which does not retain prohibited cardholder data, such as full track data, card-validation codes, card not present values (CV2, CID, etc), pins or pin blocks. Storage devices on a network must be on an internal network segregated from the DMZ. All access to networked storage devices must have its authentication and communication encrypted. The PAN must be rendered unreadable through one of the following:

  • Strong one-way hash functions (hashed indexes) with salts
  • Truncation
  • Index tokens and pads (pads must be securely stored)
  • Strong cryptography with associated key management processes and procedures

PCI Requirements Reference:

1.3.6 Place system components that store cardholder data (such as a database) in an internal network zone, segregated from the DMZ and other untrusted networks.

3.2.1 Do not store the full contents of any track (from the magnetic stripe located on the back of a card, equivalent data contained on a chip, or elsewhere) after authorization. This data is alternatively called full track, track, track 1, track 2, and magnetic-stripe data. Note: In the normal course of business, the following data elements from the magnetic stripe may need to be retained:

–   The cardholder’s name

–   Primary account number (PAN)

–   Expiration date

–   Service code To minimize risk, store only these data elements as needed for business.

3.2.2 Do not store the card verification code or value (three-digit or four-digit number printed on the front or back of a payment card used to verify card-not-present transactions) after authorization.

3.2.3 Do not store the personal identification number (PIN) or the encrypted PIN block after authorization.

3.4 Render PAN unreadable anywhere it is stored (including on portable digital media, backup media, and in logs) by using any of the following approaches:

–   One-way hashes based on strong cryptography, (hash must be of the entire PAN)

–   Truncation (hashing cannot be used to replace the truncated segment of PAN)

–   Index tokens and pads (pads must be securely stored)

–   Strong cryptography with associated key-management processes and procedures.

The MINIMUM account information that must be rendered unreadable is the PAN.

If for some reason, a company is unable to encrypt cardholder data, refer to PCI DSS Appendix B: “Compensating Controls for Encryption of Stored Data.”

Members of the Information Security Team must be informed of information security issues and vulnerabilities applicable to Naturem computing systems. When security issues are identified, the Information Security Team is responsible for notifying appropriate personnel, including system and network administrators.

The primary method for identifying new threats as they arise will be through vendor and security specific Internet mailing lists. Although not complete, the following lists should be subscribed to as well as other vendor lists applicable to Naturem specific software packages and systems:

  • Common Vulnerability Scoring System (CVSS-SIG) – http://www.first.org/cvss/

Naturem System Configuration Standards (Appendix F – a model form is shown illustrating the minimum data to be captured electronically or on hard copy) must be updated to reflect measures required for protection from any newly discovered vulnerability.

PCI Requirements Reference:

2.2 Develop configuration standards for all system components. Assure that these standards address all known security vulnerabilities and are consistent with industry-accepted system hardening standards.

Sources of industry-accepted system hardening standards may include, but are not limited to:

  • Center for Internet Security (CIS)
    • International Organization for Standardization (ISO)
    • SysAdmin Audit Network Security (SANS) Institute

–   National Institute of Standards Technology (NIST).

6.1.a Examine policies and procedures to verify that processes are defined for the following:

–   To identify new security vulnerabilities

–   To assign a risk ranking to vulnerabilities that includes identification of all “high risk” and “critical” vulnerabilities.

–   To use reputable outside sources for security vulnerability information.

  • Vulnerability Risk Ranking

The risk ranking process at Naturem must consider the possible risks to the cardholder data environment (CDE) to determine which are the most significant to a specific system or component and implement prioritized deployment. Determining which risks to address and the optimum strategy for mitigating said risks is responsibility of the Information Security Team. The vulnerability risk ranking process is based on the Common Vulnerability Scoring System (CVSS) under the custodial care of the Forum of Incident Response and Security Teams (FIRST): http://www.first.org/cvss/

The vulnerability scanning solutions utilised by Naturem (QualysGuard PCI and Tenable Network Security’s Nessus) include within their reports a CVSS Base Score. It is the responsibility of the IT Security Team to use the NIST CVSS v2.0 calculator as described within the Naturem Vulnerability Risk Ranking Procedure v1.0 to provide contextualized scoring to the Naturem CDE by defining the Temporal and Environmental Metrics.

PCI Requirements Reference:

6.2 Establish a process to identify security vulnerabilities, using reputable outside sources for security vulnerability information, and assign a risk ranking (for example, as “high,” “medium,” or “low”) to newly discovered security vulnerabilities.

Note: Risk rankings should be based on industry best practices as well as consideration of potential impact. For example, criteria for ranking vulnerabilities may include consideration of the CVSS base score, and/or the classification by the vendor, and/or type of systems affected. Methods for evaluating vulnerabilities and assigning risk ratings will vary based on an organization’s environment and risk-assessment strategy. Risk rankings should, at a minimum, identify all vulnerabilities considered to be a “high risk” to the environment. In addition to the risk ranking, vulnerabilities may be considered “critical” if they pose an imminent threat to the environment, impact critical systems, and/or would result in a potential compromise if not addressed. Examples of critical systems may include security systems, public-facing devices and systems, databases, and other systems that store, process, or transmit cardholder data.

  • Vulnerability Testing

The Information Security Team is responsible for conducting internal and external network vulnerability scans at least quarterly and after any significant change in the network (e.g., new system component installations, changes in network topology, firewall rule modifications, product upgrades). This process includes identifying any unauthorized wireless devices on the network.

Additional external vulnerability scans must be performed by a scan vendor approved by the payment card industry at least quarterly. Penetration tests at both the application and network layer must be performed annually or after any significant change in the network. Networks and systems that fall under payment card system scope must also be monitored by an intrusion detection/prevention system that alerts personnel of potential compromises. All confirmed and potential vulnerabilities identified through vulnerability scans and penetration tests will be communicated to appropriate personnel within Naturem for assessment and remediation. All high-level vulnerabilities must be corrected utilizing the Change Control Naturem Policy. Follow up scans must be performed to confirm compliance with Naturem security standards as well as the ASV Program Guide requirements (for example, no vulnerabilities rated higher than a 4.0 by the CVSS and no automatic failures

The Chief Technical Officer must coordinate an annual formal risk assessment process that identifies any existing or new threats and vulnerabilities to ensure Naturem assets are adequately protected.

PCI Requirements Reference:

11.1 Implement processes to test for the presence of wireless access points (802.11), and detect and identify all authorized and unauthorized wireless access points on a quarterly basis. Note: Methods that may be used in the process include but are not limited to wireless network scans, physical/logical inspections of system components and infrastructure, network access control (NAC), or wireless IDS/IPS. Whichever methods are used, they must be sufficient to detect and identify both authorized and unauthorized devices.

11.2 Run internal and external network vulnerability scans at least quarterly and after any significant change in the network (e.g., new system component installations, changes in network topology, firewall rule modifications, product upgrades).

11.3 Implement a methodology for penetration testing that includes the following:

–   Is based on industry-accepted penetration testing approaches (for example, NIST SP800-115)

–   Includes coverage for the entire CDE perimeter and critical systems

–   Includes testing from both inside and outside the network

–   Includes testing to validate any segmentation and scope-reduction controls

–   Defines application-layer penetration tests to include, at a minimum, the vulnerabilities listed in Requirement 6.5

–   Defines network-layer penetration tests to include components that support network functions as well as operating systems

–   Includes review and consideration of threats and vulnerabilities experienced in the last 12 months

–   Specifies retention of penetration testing results and remediation activities results.

11.4 Use intrusion-detection and/or intrusion-prevention techniques to detect and/or prevent intrusions into the network. Monitor all traffic at the perimeter of the cardholder data environment as well as at critical points in the cardholder data environment, and alert personnel to suspected compromises.

Keep all intrusion-detection and prevention engines, baselines, and signatures up to date.

12.1.2 Implement a risk-assessment process that:

–   Is performed at least annually and upon significant changes to the environment (for example, acquisition, merger, relocation, etc.),

–   Identifies critical assets, threats, and vulnerabilities, and

–   Results in a formal, documented analysis of risk. Examples of risk-assessment methodologies include but are not limited to OCTAVE, ISO 27005 and NIST SP 800-30.

  • Security Patch Deployment

All security patches, hot-fixes and service packs identified by the Information Security

Team or system administrators must be applied to applicable systems within (30) days of vendor release. As with any change to the environment the change management process must be followed.

PCI Requirements Reference:

6.2 Ensure that all system components and software are protected from known vulnerabilities by installing applicable vendor-supplied security patches. Install critical security patches within one month of release.

Note: An organization may consider applying a risk-based approach to prioritize their patch installations. For example, by prioritizing critical infrastructure (for example, public-facing devices and systems, databases) higher than less-critical internal devices, to ensure high-priority systems and devices are addressed within one month, and addressing less critical devices and systems within three months.

All applicable systems must be configured with Information Security Team approved anti-virus/anti-spyware/anti-adware/anti-rootkit software. The software must be configured to scan in real-time, log anti-virus events with routing to a central logging solution, and end-users must not be able to configure or disable the software. The software must be configured to perform weekly scans. The preferred deployment scenario should use a central management console, if the number of systems and utilised solution justify that.

PCI Requirements Reference:

5.1 Deploy anti-virus software on all systems commonly affected by viruses (particularly personal computers and servers).Note: Systems commonly affected by viruses typically do not include UNIX based operating systems or mainframes.

5.1.1 Ensure that anti-virus programs are capable of detecting, removing, and protecting against all known types of malicious software.

All systems with anti-virus software must be configured to update virus signatures on at least a daily basis.

PCI Requirements Reference:

5.2 Ensure that all anti-virus mechanisms are maintained as follows:

–   Are kept current,

–   Perform periodic scans

–   Generate audit logs which are retained per PCI DSS Requirement 10.7.

Anti-virus software must alert the Information Security Team in real-time to the detection of a virus. The Information Security Team will determine what steps to take based on the Incident Response Policy. Retention of Anti-Virus software logs will be in accordance with the Data Retention and Disposal Policy.

PCI Requirements Reference:

Audit Procedure 5.2.a Examine policies and procedures to verify that anti-virus software and definitions are required to be kept up to date.

5.2.b Examine anti-virus configurations, including the master installation of the software to verify anti-virus mechanisms are:

5.2.d Examine anti-virus configurations, including the master installation of the software and a sample of system components, to verify that:

–   Anti-virus software log generation is enabled, and

–   Logs are retained in accordance with PCI DSS Requirement 10.7.

The backup media for each system is relocated to a secure off-site storage area.

The off-site storage location must be visited annually by management or a member of the

Information Security Team to confirm that it is physically secure and fireproof.

PCI Requirements Reference:

9.5.1 Store media backups in a secure location, preferably an off-site facility, such as an alternate or backup site, or a commercial storage facility. Review the location’s security at least annually.

Offline storage media utilized for archival or back-up purposes must be handled and retained in a secured environment such that only Naturem personnel and contracted storage facility personnel have access to the archival media. All media couriers and transport mechanisms must be approved by the Information Security Team.

Positive log-out and log-in of archive media will take place during all archive media transfers. All media that is transferred from one location to another should be logged as being transferred, by whom, where, and was it properly received, with signature from management. The Backup Media Transfer Log is located in Appendix H (A model form is shown illustrating the minimum data to be captured electronically or on hard copy. All media containing confidential or sensitive data must be classified and identifiable as such prior to transfer as detailed in the Data Classification and Control Policy.

PCI Requirements Reference:

9.6.1 Classify media so the sensitivity of the data can be determined.

9.6.2 Send the media by secured courier or other delivery method that can be accurately tracked.

9.6.3 Ensure management approves any and all media that is moved from a secured area (including when media is distributed to individuals).

All media used will be classified as confidential or sensitive and assigned a unique tracking number or similar feature that uniquely identifies the media. All media must be registered with the Information Security Team for tracking prior to use.

Annual inventories of all stored media will take place. The Information Security Team will compare their list of in-use media with records at the storage facility using the Media Inventory Log (Appendix D A model form is shown illustrating the minimum data to be captured electronically or on hard copy.

PCI Requirements Reference:

9.7.1 Properly maintain inventory logs of all media and conduct media inventories at least annually.

10.5 Media Destruction

All media that is no longer needed or has reached end-of-life must be destroyed or rendered unreadable so that no data may be extracted. Information on acceptable destruction techniques is detailed in the Data Retention and Disposal policy.

PCI Requirements Reference:

9.8 Destroy media when it is no longer needed for business or legal reasons as follows:

9.8.1 Shred, incinerate, or pulp hard-copy materials so that cardholder data cannot be reconstructed. Secure storage containers used for materials that are to be destroyed.

9.8.2 Render cardholder data on electronic media unrecoverable so that cardholder data cannot be reconstructed.

  1. ENCRYPTION POLICY
    1. Policy applicability

This policy documents encryption standards that must be applied to all applicable mechanisms and systems on Naturem networks and data repositories, whether managed by employees or by third parties. This policy also applies to the management of encryption keys which may be shared with customers to exchange confidential information. Documentation provided to customers who have a need to exchange encryption keys with Naturem must include these guidelines. Exemptions from this policy will be permitted only if approved in advance and in writing by the Chief Technical Officer.

  1. Encryption Key Management

Keys must be generated, accessed, distributed and stored in a controlled and secured manner.

  1. Key Access

Access to encryption key components will only be granted to those custodians specifically requiring access due to job function. All access may only be granted by the Chief Technical Officer and those requiring access must have so noted on their Authorization Request Form (Appendix B -a model form is shown illustrating the minimum data to be captured electronically or on hard copy. Additionally, these users must sign the Encryption Key Custodianship Form (Appendix I) A model form is shown illustrating the minimum data to be captured electronically or on hard copy. These forms will be held in the employee’s Human Resources file.

PCI Requirements Reference:

3.5.2 Restrict access to cryptographic keys to the fewest number of custodians necessary.

3.6.8 Requirement for cryptographic key custodians to formally acknowledge that they understand and accept their key-custodian responsibilities.

  1. Split Knowledge and Dual Control

Two custodians authorized by the Information Security Team, are required to collaborate to perform any symmetric key action (such as key generation or loading the key). Additionally, no single custodian may know or have access to all pieces of a symmetric data encryption key.

PCI Requirements Reference:

3.6.6 If manual clear-text cryptographic key management operations are used, these operations must be managed using split knowledge and dual control (for example, requiring two or three people, each knowing only their own key component, to reconstruct the whole key).

Note: Examples of manual key management operations include, but are not limited to: key generation, transmission, loading, storage and destruction.

Note: Numerous industry standards for key management are available from various resources including NIST, which can be found at http://csrc.nist.gov.

  1. Key Generation
  2. Only strong encryption keys are to be used. Creation of encryption keys must be accomplished using a random or pseudo-random number generation algorithm.

Generating encryption keys must be accomplished by two custodians authorized by the Information Security Team. Each custodian will generate one clear text piece that will be used to create the encryption key. To prevent unauthorized substitution of keys physical and logical access to the key generating procedures and mechanisms must be secured.

PCI Requirements Reference:

3.6.1 Generation of strong cryptographic keys.

3.6.7 Prevention of unauthorized substitution of cryptographic keys.

  1. Key Distribution

Only custodians authorized by the Information Security Team are allowed to retrieve key components from secure storage or distribute keys. Custodians must document all such actions in the Encryption Key Management Log (Appendix J) A model form is shown illustrating the minimum data to be captured electronically or on hard copy. The encryption keys must be placed in secure packaging prior to being returned to storage.

PCI Requirements Reference:

3.6.2 Secure cryptographic key distribution.

  1. Key Storage

All data encryption keys must be stored encrypted and in a secure location. Key-encrypting keys must be stored separate from data-encrypting keys within applicable applications.

Clear-text backups of encryption key components must be stored separately in tamper-evident packaging in a secure location.

PCI Requirements Reference:

3.5.4 Store cryptographic keys securely in the fewest possible locations and forms.

Note: This requirement also applies to key-encrypting keys used to protect data-encrypting keys-such key-encrypting keys must be at least as strong as the data-encrypting key.

3.6.3 Secure cryptographic key storage.

  1. Key Changes and Destruction

An encryption key change is the process of generating a new key, and should the circumstances dicatate, decrypting the current production data and re-encrypting the confidential data with the new key. All data encryption keys must be changed when circumstances dictate a change to maintain encryption or key integrity as well as according to the following cryptoperiods based on the type of encryption algorithm and key length.

ProtocolKey size (bits)Crypto period
RSA409610 years
RSA20485 year
AES25610 years
AES1286 month

The following dictates additional conditions when a key change is required:

  • Regular Rotation: Keys must be changed a minimum of 1 time per year.
  • Suspicious Activity: This change is driven by any activity related to the key process which raises concern regarding the security of the existing key.
  • Resource Change: Keys must be changed if a resource with knowledge of the keys terminates employment or assumes a new job role that no longer requires access to an encryption process.
  • Technical Requirement: Keys must be changed if the key in place has become questionable due to a technical issue such as corruption or instability.
  • Encryption keys no longer in service are to be disposed of in accordance with the process outlined in the Data Retention and Disposal Policy.

PCI Requirements Reference:

3.6.4 Cryptographic key changes for keys that have reached the end of their cryptoperiod (for example, after a defined period of time has passed and/or after a certain amount of cipher-text has been produced by a given key), as defined by the associated application vendor or key owner, and based on industry best practices and guidelines (for example, NIST Special Publication 800-57).

Note: Numerous industry standards for key management are available from various resources including NIST, which can be found at http://csrc.nist.gov.

3.6.5 Retirement or replacement (for example, archiving, destruction, and/or revocation) of keys as deemed necessary when the integrity of the key has been weakened (for example, departure of an employee with knowledge of a clear-text key component), or keys are suspected of being compromised.

  1. Transmission over Un-trusted Networks

Confidential and sensitive information must be encrypted during transmission over networks in which it is easy and common for the data to be intercepted, modified or diverted, Some examples of strong encryption that is acceptable are:

  • Transport Layer Security (TLS)
  • Internet Protocol Security (IPSEC)
  • Secure Shell (SSH)
  • Secure FTP and FTP over SSL (SFTP & FTP-S)

Due to the fact that these protocols support various encryption algorithms and key lengths (including known to be weak or compromised ones) it is imperative that the implementation and configuration of components using these protocols follows best practices based on industry standards.

PCI Requirements Reference:

4.1 Use strong cryptography and security protocols to safeguard sensitive cardholder data during transmission over open, public networks, including the following:

–   Only trusted keys and certificates are accepted.

–   The protocol in use only supports secure versions or configurations.

–   The encryption strength is appropriate for the encryption methodology in use.

  1. Email Transmission of Confidential Information

Confidential and sensitive information is never to be sent unencrypted through email or other messaging technologies. Employees, with a valid business justification, must be issued relevant for the messaging technology encryption software by the Information Security Team.

PCI Requirements Reference:

4.2 Never send unprotected PANs by end-user messaging technologies (for example, e-mail, instant messaging, SMS, chat, etc.).

  1. Encryption of Wireless Networks

All wireless networks in use at Naturem facilities must be protected through secure data encryption; the current minimum standards are WPA2. Wired Equivalent Privacy (WEP) is expressly prohibited. Under no circumstances should the encryption strength be configured to be less than the equivalent of 128 bits symmetric key encryption. Wireless encryption keys will be changed every ninety (90) days or whenever an administrator with knowledge of the keys is terminated.

PCI Requirements Reference:

4.1.1 Ensure wireless networks transmitting cardholder data or connected to the cardholder data environment, use industry best practices to implement strong encryption for authentication and transmission.

  1. SPECIAL TECHNOLOGIES USAGE POLICY
    1. Policy Applicability

All users of special technologies deployed on Naturem networks, whether employees or contractors, must follow this policy. Exemptions from this policy will be permitted only if approved in advance and in writing by the Chief Technical Officer. Currently, “special technologies” refers to modem use, modem or VPN access, wireless networks and other employee-facing technologies within the Naturem computing environment. This policy will be modified in the future to include any new “special technologies” used.

PCI Requirements Reference:

12.3 Develop usage policies for critical technologies and define proper use of these technologies.

Note: Examples of critical technologies include, but are not limited to, remote access and wireless technologies, laptops, tablets, removable electronic media, e-mail usage and Internet usage.

Ensure these usage policies require the following:

  1. Approval

The Information Security Team must explicitly approve any use or deployment of special technologies by job function role or on an individual basis. For general user application, this includes: remote VPN access  and wireless network access. These approvals must be documented on the user’s Authorization Request Form (Appendix B A model form is shown illustrating the minimum data to be captured electronically or on hard copy.

PCI Requirements Reference:

12.3.1 Explicit approval by authorized parties.

  1. Authentication

User authentication mechanisms, where possible, must be integrated into the current Naturem authentication systems. All device use must be authenticated at minimum with username and password or other authentication item (for example, token) Under no circumstances may the user authentication requirements be less strict than currently defined policies and procedures (e.g., complex passwords, password change interval, etc.).

All remote access to the Naturem network using these technologies must be authenticated via a strong two-factor authentication scheme approved by the Information Security Team.

PCI Requirements Reference:

8.3 Secure all individual non-console administrative access and all remote access to the CDE using multi-factor authentication.

Note: Multi-factor authentication requires that a minimum of two of the three authentication methods (see Requirement 8.2 for descriptions of authentication methods) be used for authentication. Using one factor twice (for example, using two separate passwords) is not considered multi-factor authentication.

  1. Device Inventory

All approved user devices (personal modems and wireless network interfaces) must be noted on the Special Technologies Device Inventory (Appendix K A model form is shown illustrating the minimum data to be captured electronically or on hard copy. All approved users of these technologies must be noted on the Special Technologies User List (Appendix L A model form is shown illustrating the minimum data to be captured electronically or on hard copy. Users that must be documented include:

  • Wireless network users
  • Employees with VPN access
  • Vendors with remote/VPN access

PCI Requirements Reference:

12.3.3 A list of all such devices and personnel with accesst

  1. Device Identification

All personal modems and wireless access points must be labeled with the device owner, contact information and device purpose.

PCI Requirements Reference:

12.3.4 A method to accurately and readily determine owner, contact information, and purpose (for example, labeling, coding, and/or inventorying of devices)

  1. Acceptable Use

Acceptable use of Naturem special technologies is subject to the same guidelines and restrictions put forth in the Security Awareness and Acceptable Use Policy (Appendix A).

PCI Requirements Reference:

12.3.5 Acceptable uses for the technology.

  1. Permitted Locations

The Information Security Team must authorize the placement of any wireless access points and dial-in modems. Dial-in modems are typically limited to the data center. Wireless access points are normally placed in the ceiling plenum to protect them from tampering. The use of these devices must be logged according to the Special Technologies Device Inventory (Appendix K A model form is shown illustrating the minimum data to be captured electronically or on hard copy) and Special Technologies User List (Appendix L A model form is shown illustrating the minimum data to be captured electronically or on hard copy.

PCI Requirements Reference:

12.3.6 Acceptable network locations for the technologies.

  1. Approved Products

Only Information Security Team approved devices may be deployed into the Naturem network. The use of these devices must be logged according to the Special Technologies Device Inventory (Appendix K) and Special Technologies User List (Appendix L A model form is shown illustrating the minimum data to be captured electronically or on hard copy)

PCI Requirements Reference:

12.3.7 A list of company-approved products.

12.9 Session Disconnect

All dial-in modems, modem banks and VPN concentrators/termination points (for client and not site-to-site connectivity) must be configured to automatically disconnect sessions after thirty (30) minutes of inactivity.

PCI Requirements Reference:

12.3.8 Automatic disconnect of sessions for remote-access technologies after a specific period of inactivity

12.10 Vendor Connections

VPN connections and other remote-access technologies, systems and accounts used solely for the purpose of vendor maintenance and support must remain disconnected and/or disabled until required. Activating these remotes access paths requires approval from the Information Security Team or established problem management procedures and they must be disabled immediately after use.

PCI Requirements Reference:

12.3.9 Activation of remote-access technologies for vendors and business partners only when needed by vendors and business partners, with immediate deactivation after use.

12.11 Cardholder Data Access

If any cardholder data is available through remote-access connections special precautions must be taken. The following are prohibited:

  • Storage of the company information onto local hard drives, floppy disks, and other media is prohibited.
  • Cut, paste, and print functions of remote PCs is prohibited for the duration of the connection.

PCI Requirements Reference:

12.3.10 For personnel accessing cardholder data via remote-access technologies, prohibit the copying, moving, and storage of cardholder data onto local hard drives and removable electronic media, unless explicitly authorized for a defined business need.

Where there is an authorized business need, the usage policies must require the data be protected in accordance with all applicable PCI DSS Requirements.

  1. SOFTWARE DEVELOPMENT POLICY
    1. Development Environment

A test/development environment, separate from the production environment, must be used to test all new software. If the network has network connectivity with the production Naturem network, access controls must be in place to enforce the separation.

Production card holder data will not be used for testing and development purposes without being sanitized. Test personnel should make every effort to use mock data only for testing on non-production systems and software. If it is determined that production card holder data must be used in testing, the Security Council must review and approve the business justification, the testing window will have as short a duration as possible, all PCI controls must be enforced on the systems under test, and the Security Council must be notified of test results, and verification that production data has been scrubbed after close of testing window.

All test data, custom application accounts, usernames and passwords must be removed at the conclusion of testing, and in all cases before software becomes active. All code promotion to the production environment will be accomplished by the System Administrators. Under no circumstances will the Development Department have full time read/write access to production applications or data. Under emergency situations developers may assist in troubleshooting utilizing an Emergency ID described in section 3.6.1 Information Security Team Responsibilities.

PCI Requirements Reference:

  • Change control procedures must include the following:

6.4.5.1  Documentation of impact.

6.4.5.2  Documented change approval by authorized parties.

6.4.5.3 Functionality testing to verify that the change does not adversely impact the security of the system.

6.4.5.4  Back-out procedures.

6.4.1 Separate development/test environments from production environments, and enforce the separation with access controls.

6.4.2 Separation of duties between development/test and production environments

6.4.3 Production data (live PANs) are not used for testing or development.

6.4.4 Removal of test data and accounts from system components before the system becomes active / goes into production.

  1. Secure Software Development Procedures
    1. Development Life-Cycle

Internal and 3rd party development of proprietary software must utilize industry recognized best practices for software development such as described at http://www.oracle.com/technetwork/java/seccodeguide-139067.html Security checks and control measures must be considered throughout the development life-cycle.

The high level overview of the security measures taking place within each phase of the Naturem development process are as follows:

  • Requirements Analysis – developers should determine whether application requirements are inherently insecure.
  • Design – application components must be planned in a manner consistent with data and network security.
  • Development – developers must consider all application vulnerabilities (i.e.: memory bound issues, privilege and access bypass, etc.).
  • QA Implementation – implementation must not compromise security controls already in place, or introduce new vulnerabilities.
  • QA Testing – in addition to functional and efficiency testing, all security features of the application must be tested.
  • Documentation – all application feature and implementation documentation must include direction on proper security configurations.
  • Production Implementation – implementation must not compromise security controls already in place, or introduce new vulnerabilities.
  • Production Testing – in addition to functional and efficiency testing, all security features of the application must be tested.
  • Maintenance – all future application maintenance should not compromise security controls already in place, or introduce new vulnerabilities. Any new code must be reviewed and tested as detailed above.

PCI Requirements Reference:

6.3 Develop internal and external software applications (including web-based administrative access to applications) securely, as follows:

–   In accordance with PCI DSS (for example, secure authentication and logging)

–   Based on industry standards and/or best practices.

–   Incorporating information security throughout the software-development life cycle

6.3.2 Review custom code prior to release to production or customers in order to identify any potential coding vulnerability (using either manual or automated processes) to include at least the following:

–   Code changes are reviewed by individuals other than the originating code author, and by individuals knowledgeable about code-review techniques and secure coding practices.

–   Code reviews ensure code is developed according to secure coding guidelines

–   Appropriate corrections are implemented prior to release.

–   Code-review results are reviewed and approved by management prior to release.

Note: This requirement for code reviews applies to all custom code (both internal and public-facing), as part of the system development life cycle. Code reviews can be conducted by knowledgeable internal personnel or third parties. Public-facing web applications are also subject to additional controls, to address ongoing threats and vulnerabilities after implementation, as defined at PCI DSS Requirement 6.6.

  1. Internally Developed Applications

In addition to the Development Life-Cycle security measures that take place throughout the application development life-cycle, special care should be given to Naturem applications that are web-based. All Naturem developers will receive training on secure coding practices. All development must be done taking the OWASP guidelines into account, located at http://www.owasp.org. Specifically, the following vulnerabilities must be considered and checked for during the Code Review and Testing phases:

  • Unvalidated Input
  • Malicious Use of User IDs
  • Malicious Use of Account Credentials and Session Cookies
  • Cross-Site Scripting
  • Cross-site request forgery
  • Buffer Overflows
  • SQL Injection and other Command Injection Flaws
  • Error Handling Flaws
  • Insecure Cryptographic Storage
  • Denial of Service
  • Insecure Configuration Management
  • Insecure Direct Object references

Annually, and whenever significant modifications have taken place, all web-based applications will be put through an application-specific penetration test. All custom code is to be reviewed by an organization that specializes in application security or an application layer firewall in front of web-facing applications.

PCI Requirements Reference:

–   Reviewing public-facing web applications via manual or automated application vulnerability security assessment tools or methods, at least annually and after any changes Note: This assessment is not the same as the vulnerability scans performed for Requirement 11.2.

–   Installing an automated technical solution that detects and prevents web-based attacks (for example, a web-application firewall) in front of public-facing web applications, to continually check all traffic.

Note: “An organization that specializes in application security” can be either a third-party company or an internal organization, as long as the reviewers specialize in application security and can demonstrate independence from the development team.

  1. Cardholder Data and Processing Applications

All Naturem proprietary or custom applications dealing with the processing or retrieval of cardholder information must be configured in a manner which masks or truncates the displayed credit card number. If cardholder information is to be masked only the first 6 and any other 4 digits may remain displayed. If the application is designed for a specific purpose in which the full credit card number must be displayed approval must be given by the Information Security Team.

PCI Requirements Reference:

3.3 Mask PAN when displayed (the first six and last four digits are the maximum number of digits to be displayed), such that only personnel with a legitimate business need can see more than the first six/last four digits of the PAN.

Note: This requirement does not supersede stricter requirements in place for displays of cardholder data—for example, legal or payment card brand requirements for point-of-sale (POS) receipts.

  1. INCIDENT RESPONSE PLAN AND PROCEDURES
    1. Incident Identification

Employees must be aware of their responsibilities in detecting security incidents to facilitate the incident response plan and procedures. All employees have the responsibility to assist in the incident response procedures within their particular areas of knowledge, expertise and responsibility. Some examples of security incidents that an employee might recognize in their day to day activities include, but are not limited to:

  • Theft, damage, or unauthorized access (e.g., unauthorized logins, papers missing from their desk, broken locks, missing log files, alert from security guard, video evidence of a break-in or unscheduled/unauthorized physical entry)
  • Fraud – Inaccurate information within databases, logs, files or paper records
  • Abnormal system behavior (e.g., unscheduled system reboot, unexpected messages, abnormal errors in system log files or on terminals)
  • Security event notifications (e.g., file integrity alerts, intrusion detection alarms, physical security alarms such as fire alarms, environmental alarms, natural disaster alerts)

All employees, regardless of job responsibilities, should be aware of the potential incident identifiers and who to notify in these situations. In all cases, every employee should report incidents per the instructions under 14.2 Incident Reporting unless they are assigned other activities within the incident response plan.

  1. Reporting and Incident Declaration Procedures

The Information Security Team should be notified immediately of any suspected or confirmed security incidents involving Naturem computing assets, particularly any critical systems. If it is unclear as to whether a situation should be considered a security incident, the Information Security Team should be contacted to evaluate the situation.

With the exception of steps outlined below, it is imperative that any investigative or corrective action be taken only by Information Security Team personnel or under the oversight of Information Security Team personnel, to assure the integrity of the incident investigation and recovery process. When faced with a potential situation you should do the following:

  • If the incident involves a compromised computer system.
  • Do not alter the state of the computer system.
  • The computer system should remain on and all currently running computer programs left as is. Do not shutdown the computer or restart the computer.
  • Immediately disconnect the computer from the network by removing the network cable from the back of the computer.
  • Reporting the security incident.
  • Contact the Information Security Team to report any suspected or actual incidents.
  • No one should communicate with anyone outside of their supervisor(s) or the
  • Information Security Team about any details or generalities surrounding any suspected or actual incident. All communications with law enforcement or the public will be coordinated by the Information Security Team.
  • Document any information you know while waiting for the Information Security Team to respond to the incident. This must include date, time, and the nature of the incident, if known. Any information you can provide will aid in responding in an appropriate manner.

PCI Requirements Reference:

12.10 Implement an incident response plan. Be prepared to respond immediately to a system breach.

12.10.1 Create the incident response plan to be implemented in the event of system breach. Ensure the plan addresses the following, at a minimum:

–   Roles, responsibilities, and communication and contact strategies in the event of a compromise including notification of the payment brands, at a minimum

–   Specific incident response procedures

–   Business recovery and continuity procedures

–   Data backup processes

–   Analysis of legal requirements for reporting compromises

–   Coverage and responses of all critical system components

–   Reference or inclusion of incident response procedures from the payment brands.

  1. Incident Severity Classification

The Information Security Team will first attempt to determine if the security incident justifies a formal incident response.

In cases where a security incident does not require an incident response the situation will be forwarded to the appropriate area of IT to ensure that all technology support services required are rendered. The following descriptions should be used to determine what response the Information Security Department will take.

  • Level 1 – One instance of potentially unfriendly activity (e.g., finger, unauthorized telnet, port scan, corrected virus detection, unexpected performance peak, etc.).
  • Level 2 – One instance of a clear attempt to obtain unauthorized information or access (e.g., attempted download of secure password files, attempt to access restricted areas, single computer successful virus infection on a non-critical system, unauthorized vulnerability scan, etc.) or a second Level 1 attack.
  • Level 3 – Serious attempt or actual breach of security (e.g., multi-pronged attack, denial of service attempt, virus infection of a critical system or the network, successful buffer/stack overflow, successful unauthorized access to sensitive or critical data or systems, broken lock, stolen papers, etc.) or a second Level 2 attack.
  • Any Level 1 type incident occurring against systems storing sensitive or confidential data or originating from unauthorized internal systems is classified as a Level 2.
  1. Incident Response
    1. Typical Response

Responses can include or proceed through the following stages: identification, severity classification, containment, eradication, recovery and root cause analysis resulting in improvement of security controls. The following actions should be taken by the Information

Security Department once an incident has been identified and classified.

  1. Level 1

Contain and Monitor

  1. If possible, record the user, IP address and domain of intruder.
  2. Utilize approved technology controls to temporarily or permanently block the intruder’s access.
  3. Maintain vigilance for future break-in attempts from this user or IP address.
  1. Level 2

Contain, Monitor and Warn

  1. Collect and protect information associated with the intrusion.
  2. Utilize approved technology controls to temporarily or permanently block the intruder’s access.
  3. Research the origin of the connection.
  4. Contact ISP and ask for more information regarding the attempt and intruder.
  5. Research potential risks related to intrusion method attempted and re-evaluate for higher classification and incident containment, eradication, and recovery as described for Level 3 incident classifications.
  6. Upon identification, inform malicious user of our knowledge of their actions and warn of future recriminations if attempt is repeated. If an employee is the malicious user management should work with Human Resources to address the Acceptable Use violation appropriately.
  1. Level 3

Contain, Eradicate, Recover and perform Root Cause Analysis

  1. If the incident involved credit card systems the Acquirer and applicable card associations must be notified. See section 14.2 for more details.
  2. Contain the intrusion and decide what action to take. Consider unplugging the network cables, applying highly restrictive ACL’s, deactivating or isolating the switch port, deactivating the user ID, terminating the user’s session/change password etc.
  3. Collect and protect information associated with the intrusion via offline methods. In the event that forensic investigation is required the Information Security Team will work with legal and management to identify appropriate forensic specialists.
  4. Notify management of the situation and maintain notification of progress at each following step.
  5. Eliminate the intruder’s means of access and any related vulnerabilities.
  6. Research the origin of the connection.
  7. Contact ISP and ask for more information regarding attempt and intruder, reminding them of their responsibility to assist in this regard.
  8. Research potential risks related to or damage caused by intrusion method used.
  1. Cardholder Data Compromise – Special Response & Notification Procedures

For any incidents involving potential compromises of credit card information, the Information Security Team will use the following procedure:

  1. Contain and limit the exposure. Conduct a thorough investigation of the suspected or confirmed loss or theft of account information within 24 hours of the compromise. To facilitate the investigation:
    1. Log all actions taken (e.g., bound notebook, video camera, etc).
    1. Utilize chain of custody techniques during all transfers of equipment and information related to the incident.
    1. Do not access or alter compromised systems (e.g., do not log on or change passwords; do not log in as ROOT).
    1. Do not turn off the compromised machine. Instead, isolate compromised systems from the network (e.g., unplug the network cable, deactivate switch port, isolate to contained environment e.g. isolated VLAN). Utilize Disaster Recovery / Business continuity procedures to recover business processes.
    1. Preserve logs and electronic evidence.
    1. If using a wireless network, change SSID on the AP and other machines that may be using this connection (with the exception of any systems believed to be compromised).
    1. Be on high alert and monitor all cardholder information systems.
  2. Alert all necessary parties. Be sure to notify:
    1. Internal or External Incident Response or Forensics Team, if they are not already involved
    1. Merchant bank
    1. U.S. Secret Service (if PCI payment data is compromised)
  3. Follow appropriate procedures for each card association which Naturem utilizes for credit card services.

Visa

Provide the compromised Visa accounts to Visa Fraud Control Group within ten (10) business days. For assistance, contact (650) 432-2978. Account numbers must be securely sent to Visa as instructed by the Visa Fraud Control Group. It is critical that all potentially compromised accounts are provided. Visa will distribute the compromised Visa account numbers to issuers and ensure the confidentiality of entity and non-public information.
