Description
When the application server is using PKI authentication, a local revocation cache must be stored for instances when the revocation cannot be authenticated through the network, but if cached authentication information is out of date, the validity of the authentication information may be questionable.

ℹ️ Check
Review System Security Plan documentation. Identify the cache timeout parameters for authentication. Standard value for admin timeout is 10 minutes; however, the ISSO may allow a case by case exception based on operational requirements. From the admin console, navigate to Security >> Global Security >> Authentication cache settings. If "Enable authentication cache" check box is set and "Cache timeout" is larger than the parameters specified in the security plan, this is a finding.
