II - Mission Support Sensitive

Rules and Groups employed by this XCCDF Profile

  • SRG-APP-000372-NDM-000297

    Group
  • The Arista Multilayer Switch must synchronize internal information system clocks to the authoritative time source when the time difference is greater than the organization-defined time period.

    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-000373-NDM-000298

    Group
  • The Arista Multilayer Switch must be configured to synchronize internal information system clocks with the primary and secondary time sources located in different geographic regions using redundant authoritative time sources.

    The loss of connectivity to a particular authoritative time source will result in the loss of time synchronization (free-run mode) and increasingly inaccurate time stamps on audit events and other ...

  • SRG-APP-000374-NDM-000299

    Group
  • The Arista Multilayer Switch must record time stamps for audit records that can be mapped to Coordinated Universal Time (UTC) or Greenwich Mean Time (GMT).

    If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis. Time stamps generated by the application include date and time. Tim...

  • SRG-APP-000411-NDM-000330

    Group
  • Arista Multilayer Switches used for nonlocal maintenance sessions must implement cryptographic mechanisms to protect the integrity of nonlocal maintenance and diagnostic communications.

    This requires the use of secure protocols instead of their unsecured counterparts, such as SSH instead of telnet, SCP instead of FTP, and HTTPS instead of HTTP.

  • SRG-APP-000412-NDM-000331

    Group
  • Arista Multilayer Switches used for nonlocal maintenance sessions must implement cryptographic mechanisms to protect the confidentiality of nonlocal maintenance and diagnostic communications.

    This requires the use of secure protocols instead of their unsecured counterparts, such as SSH instead of telnet, SCP instead of FTP, and HTTPS instead of HTTP.

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.
