The network device must prohibit the use of cached authenticators after an organization-defined time period.

Some authentication implementations can be configured to use cached authenticators.

If cached authentication information is out-of-date, the validity of the authentication information may be questionable.

The organization-defined time period should be established for each device depending on the nature of the device; for example, a device with just a few administrators in a facility with spotty network connectivity may merit a longer caching time period than a device with many administrators.

Review the network device configuration to determine if the network device or its associated authentication server prohibits the use of cached authenticators after an organization-defined time period.

If cached authenticators are used after an organization-defined time period, this is a finding.

Configure the network device or its associated authentication server to prohibit the use of cached authenticators after an organization-defined time period.
