    <GroupDescription></GroupDescription>
    Group
  • The Cisco router must be configured to allocate audit record storage capacity in accordance with organization-defined audit record storage requirements.

    &lt;VulnDiscussion&gt;In order to ensure network devices have a sufficient storage capacity in which to write the audit logs, they need to be able ...

  • SRG-APP-000360-NDM-000295

    <GroupDescription></GroupDescription>
    Group
  • The Cisco router must be configured to generate an alert for all audit failure events.

    <GroupDescription></GroupDescription>
    Group
  • The Cisco router must be configured to synchronize its clock with the primary and secondary time sources using redundant authoritative time sources.

    &lt;VulnDiscussion&gt;The loss of connectivity to a particular authoritative time source will result in the loss of time synchronization (free-run ...

    <GroupDescription></GroupDescription>
    Group
  • The Cisco router must be configured to authenticate SNMP messages using a FIPS-validated Keyed-Hash Message Authentication Code (HMAC).

    &lt;VulnDiscussion&gt;Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. B...
