The operating system, for PKI-based authentication, must implement a local cache of revocation data to support path discovery and validation in case of the inability to access revocation information via the network.

Without configuring a local cache of revocation data, there is the potential to allow access to users who are no longer authorized (users with revoked certificates).

Verify the operating system, for PKI-based authentication, implements a local cache of revocation data to support path discovery and validation in case of the inability to access revocation information via the network. If it does not, this is a finding.

Configure the operating system, for PKI-based authentication, to implement a local cache of revocation data to support path discovery and validation in case of the inability to access revocation information via the network.
