AAA Services Security Requirements Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • AAA Services must be configured to include only approved trust anchors in trust stores or certificate stores managed by the organization.

    Public key infrastructure (PKI) certificates are certificates with visibility external to organizational systems and certificates related to the internal operations of systems, such as application-...
    Rule Medium Severity
  • AAA Services must be configured to provide automated account management functions.

    Enterprise environments make account management challenging and complex. A manual process for account management functions adds the risk of a potential oversight or other error. A comprehensive acc...
    Rule Medium Severity
  • AAA Services must be configured to automatically disable accounts after a 35-day period of account inactivity.

    Attackers that are able to exploit an inactive account can potentially obtain and maintain undetected access to an application. Owners of inactive accounts will not notice if unauthorized access to...
    Rule Medium Severity
  • AAA Services must be configured to automatically audit account modification.

    Once an attacker establishes access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to simply modify ...
    Rule Medium Severity
  • AAA Services configuration audit records must identify what type of events occurred.

    Without establishing what type of event occurred, it would be difficult to establish, correlate, and investigate the events relating to an incident, or identify those responsible for one. Audit r...
    Rule Medium Severity
  • AAA Services configuration audit records must identify any individual user or process associated with the event.

    Without information that establishes the identity of the subjects (i.e., users or processes acting on behalf of users) associated with the events, security personnel cannot determine responsibility...
    Rule Medium Severity
  • AAA Services must be configured to alert the SA and ISSO when any audit processing failure occurs.

    It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without this notification, the security personnel may be unaware of an ...
    Rule Medium Severity
  • AAA Services must be configured to disable non-essential modules.

    It is detrimental for applications to provide, or install by default, functionality exceeding requirements or mission objectives. These unnecessary capabilities or services are often overlooked and...
    Rule Medium Severity
  • AAA Services must be configured to use protocols that encrypt credentials when authenticating clients, as defined in the PPSM CAL and vulnerability assessments.

    Authentication protection of the client credentials (specifically the password or shared secret) prevents unauthorized access to resources. The RADIUS protocol encrypts the password field in the ac...
    Rule High Severity
  • AAA Services must be configured to prohibit or restrict the use of organization-defined functions, ports, protocols, and/or services, as defined in the PPSM CAL and vulnerability assessments.

    In order to prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types), organizations must disable...

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
