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 If cached authentication information is out-of-date, the validity of the authentication information may be questionable.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

ℹ️ Check
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.

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