Requirement 8: Assign a unique ID to each person

Assign a unique ID to each person with computer access

Assigning a unique identification (ID) to each person with access ensures that each individual is uniquely accountable for their actions. When such accountability is in place, actions taken on critical data and systems are performed by, and can be traced to, known and authorized users and processes.

The effectiveness of a password is largely determined by the design and implementation of the authentication system—particularly, how frequently password attempts can be made by an attacker, and the security methods to protect user passwords at the point of entry, during transmission, and while in storage.

Note:

  • These requirements are applicable for all accounts, including point-of-sale accounts, with administrative capabilities and all accounts used to view or access cardholder data or to access systems with cardholder data. This includes accounts used by vendors and other third parties (for example, for support or maintenance).
  • However, Requirements 8.1.1, 8.2, 8.5, 8.2.3 through 8.2.5, and 8.1.6 through 8.1.8 are not intended to apply to user accounts within a point-of- sale payment application that only have access to one card number at a time in order to facilitate a single transaction (such as cashier accounts).

Section PCI Requirement Comments
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: Theatre Manager implements PCI standards. You may need a manual process for other applications or hardware.
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. Refer to the PCI Security Tab in System Preferences for settings. Theatre Manager enforces stronger password policies than the minimum PCI standards.
8.1.5 Manage IDs used by vendors 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.
Theatre Manager uses Teamviewer for one-time access, granted as needed.
8.1.6 Limit repeated access attempts by locking out the user ID after not more than six attempts. Theatre Manager limits incorrect password attempts to a total of 6 since the last successful attempt and locks out the account on failure.
8.1.7 Set the lockout duration to a minimum of 30 minutes or until an administrator enables the user ID. Lockout duration in Theatre Manager is permanent. Locked out employee must be re-instated by administrator.
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. Theatre Manager logs out the user after inactivity. In addition to the feature built into Theatre Manager for auto log out, you are encouraged to use the screen saver provisions that require passwords after the screen saver is activated.
8.2 In addition to assigning a unique ID, ensure proper user-authentication management for non-consumer users and administrators on all system components by employing at least one of the following methods to authenticate all users:
  • Something you know, such as a password or passphrase
  • Something you have, such as a token device or smart card, specific IP, key access to a locked room
  • Something you are, such as a biometric
 
8.2.1 Using strong cryptography, render all authentication credentials (such as passwords/phrases) unreadable during transmission and storage on all system components. Passwords are never transmitted in clear text when logging on to the database.
8.2.2 Verify user identity before modifying any authentication credential—for example, performing password resets, provisioning new tokens, or generating new keys. Only administrators are able to reset a password, reinstate an employee and/or regenerate credit card encryption keys.
8.2.3 Passwords/phrases must meet the following:
  • Require a minimum length of at least seven characters.
  • Contain both numeric and alphabetic characters. Alternatively, the passwords/phrases must have complexity and strength at least equivalent to the parameters specified above.
Theatre Manager enforces
  • Minimum 7
  • One upper
  • One lower
  • One numeric
  • One Special
  • No repeated characters
8.2.4 Change user passwords/passphrases at least once every 90 days. Theatre Manager enforces this
8.2.5 Do not allow an individual to submit a new password/phrase that is the same as any of the last four passwords/phrases he or she has used. Theatre Manager enforces 12
8.2.6 Set passwords/phrases for first- time use and upon reset to a unique value for each user, and change immediately after the first use. Theatre Manager enforces change of password at time of login for first time users
8.3 Incorporate two-factor authentication for remote network access originating from outside the network by personnel (including users and administrators) and all third parties, (including vendor access for support or maintenance).

Note: Two-factor authentication requires that 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 two-factor authentication.

Examples of two-factor tehcnologies include remote authentication and dial-in service (RADIUS) with tokens; terminal access controller access control system (TACACS) with tokens, and other technologies that facilitate two-factor authentication.

Two factor authentication means something you know and something you are given. Our QSA (the auditor who assesses Theatre Manager's ability to meet PCI compliance) has indicated that Teamviewer meets that requirement when used per the instructions. The multiple factors include:
  • The user must start the application manually (it cannot be active by default)
  • A unique Id must be provided
  • A single use token must also be provided to ArtsMan that cannot be reused.
effectively being 3 factors that must occur for access to be granted successfully.
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.
All Theatre Manager user passwords are encrypted in the database. MD5 authentication is recommended at a minimum for accessing the database (this is the default standard in the pg_hba.conf file)
8.5 Do not use group, shared, or generic IDs, passwords, or other authentication methods as follows:
  • Generic user IDs are disabled or removed.
  • Shared user IDs do not exist for system administration and other critical functions.
  • Shared and generic user IDs are not used to administer any system components.
 
8.5.1 Additional requirement for service providers only: Service providers with remote access to customer premises (for example, for support of POS systems or servers) must use a unique authentication credential (such as a password/phrase) for each customer.

Note: This requirement is not intended to apply to shared hosting providers accessing their own hosting environment, where multiple customer environments are hosted.

Arts Management does not require permanent remote access to your servers. Temporary access is always initiated by the customer as described in the teamviewer remote support help page.
8.6 Where other authentication mechanisms are used (for example, physical or logical security tokens, smart cards, certificates, etc.), use of these mechanisms must be assigned as follows:
  • Authentication mechanisms must be assigned to an individual account and not shared among multiple accounts.
  • Physical and/or logical controls must be in place to ensure only the intended account can use that mechanism to gain access.
 
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).

Access to the db is controlled by the pg_hba.conf file and it is set so that all users must log in to read data.

The user's id for the database is set by the application and not usually known.

The password in postgres is set by the application and stored encrypted. Thus, the user cannot access the database even knowing their user ID and password because it is not the same as plain-text.

8.8 Ensure that security policies and operational procedures for identification and authentication are documented, in use, and known to all affected parties.
