F5BI-LT-000203 - The BIG-IP Core implementation must be configured to deny-by-default all PKI-based authentication to virtual servers supporting path discovery and validation if unable to access revocation information via the network.

When revocation data is unavailable from the network, the system should be configured to deny-by-default to mitigate the risk of a user with a revoked certificate gaining unauthorized access. Local cached revocation data can be out of date or not able to be installed on the local system, which increases administration burden for the system.

The intent of this requirement is to deny unauthenticated users access to virtual servers in case access to OCSP (required by CCI-000185) is not available.

This requirement applies to ALGs that provide user authentication intermediary services (e.g., authentication gateway or TLS gateway). This does not apply to authentication for the purpose of configuring the device itself (device management).

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.


If user access control intermediary services are provided, configure the BIG-IP Core to deny-by-default when access to revocation information via the network is inaccessible.
