STIG ID: SRG-OS-000384-GPOS-00167 |  SRG: SRG-OS-000384 |  Severity: medium |  CCI:  | Vulnerability Id: V-203734

Vulnerability Discussion

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).

Check

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.

Fix

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.
