The VPN Gateway 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.

Description
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). This requirement only applies to components where this is specific to the function of the device or has the concept of a user (e.g., VPN or proxy capability). This does not apply to authentication for the purpose of configuring the device itself (i.e., device management).

If the VPN does not provide PKI-based user authentication intermediary services, this is not applicable. Verify the VPN 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 the VPN does not 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, this is a finding.
