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If cached authentication information is out-of-date, the validity of the authentication information may be questionable.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 must 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
From the BIG-IP GUI:
1. System.
2. Users.
3. Authentication.
4. If "User Directory" is configured for "Remote - ClientCert LDAP", verify "OCSP Response Max Age" is configured for an organization-defined time period.
Note: The OCSP Override option must be set to "on" to view the OCSP Response Max Age value.
If the BIG-IP appliance is not configured to prohibit the use of cached authenticators after an organization-defined time period, this is a finding.
✔️ Fix
From the BIG-IP GUI:
1. System.
2. Users.
