AAA Services Security Requirements Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • SRG-APP-000375

    Group
  • AAA Services must be configured with a minimum granularity of one second to record time stamps for audit records.

    Without sufficient granularity of time stamps, it is not possible to adequately determine the chronological order of records. Time stamps generated by the application include date and time. Granu...
    Rule Medium Severity
  • SRG-APP-000394

    Group
  • SRG-APP-000516

    Group
  • AAA Services must be configured to use at least two NTP servers to synchronize time.

    Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when condu...
    Rule Low Severity
  • SRG-APP-000516

    Group
  • AAA Services must be configured to authenticate all NTP messages received from NTP servers and peers.

    Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when condu...
    Rule Medium Severity
  • SRG-APP-000516

    Group
  • AAA Services must be configured to use their loopback or OOB management interface address as the source address when originating NTP traffic.

    Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when condu...

  • SRG-APP-000516

    Group
  • AAA Services must not be configured with shared accounts.

    Shared accounts configured for use on a network device do not allow for accountability or repudiation of individuals using them. If shared accounts are not changed when someone leaves the group, th...
    Rule Medium Severity
  • SRG-APP-000516

    Group
  • AAA Services used to authenticate privileged users for device management must be configured to connect to the management network.

    Using standardized authentication protocols such as RADIUS, TACACS+, and Kerberos, an authentication server provides centralized and robust authentication services for the management of network com...

  • SRG-APP-000516

    Group
  • AAA Services must be configured to use a unique shared secret for communication (i.e. RADIUS, TACACS+) with clients requesting authentication services.

    Using standardized authentication protocols such as RADIUS, TACACS+, and Kerberos, an authentication server provides centralized and robust authentication services for the management of network com...
    Rule Medium Severity
  • SRG-APP-000516

    Group
  • AAA Services must be configured to use IP segments separate from production VLAN IP segments.

    When policy assessment and remediation have been implemented and the advanced AAA server dynamic VLAN is misconfigured, logical separation of the production VLAN may not be assured. Non-trusted re...
