Discussion

Public key cryptography is a valid authentication mechanism for individuals, machines, and devices. For Public Key Infrastructure (PKI) solutions, status information for certification paths includes certificate revocation lists or certificate status protocol responses. For Personal Identity Verification (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.

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

Use the command below to display the current cached OCSP results:

- show certificate ocsp-cache

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