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 If cached authentication information is out-of-date, the validity of the authentication information may be questionable.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

| 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. |
