STIG ID: SRG-APP-000875-MFP-000280  |  SRG: SRG-APP-000875 | Severity: medium |  CCI: CCI-004068

Vulnerability Discussion

Public key cryptography is a valid authentication mechanism for individuals, machines, and devices. For PKI solutions, status information for certification paths includes certificate revocation lists or certificate status protocol responses. For PIV cards, certificate validation involves the construction and verification of a certification path to the Common Policy Root trust anchor, which includes certificate policy processing. Implementing a local cache of revocation data to support path discovery and validation also supports system availability in situations where organizations are unable to access revocation information via the network.

Check

Verify the Mainframe Product is configured to implement a local cache of revocation data to support path discovery and validation.

If the Mainframe Product is not configured to implement a local cache of revocation data to support path discovery and validation, this is a finding.

Fix

Configure the Mainframe Product to implement a local cache of revocation data to support path discovery and validation.
