The HYCU server must prohibit the use of cached authenticators after an organization-defined time period.
An XCCDF Rule
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 If cached authentication information is out-of-date, the validity of the authentication information may be questionable.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.
