Fix Recommendation

Implement a Certificate Revocation List (CRL) import process and configure the application to check the CRL if OCSP is not available.

Check Contents

Review the application documentation and interview the system administrator to identify how the application checks certificate revocation.

If the application resides on the SIPRNET and does not have access to the root CAs this requirement is not applicable.

Different application frameworks may handle this requirement for the developer or the developer may have chosen to implement their own implementation for managing and implementing the CRL.

Have the administrator demonstrate the process used for obtaining and importing the CRL. CAs may publish the CRL in an LDAP directory or it may be posted to an HTTP server.

Verify the application is configured to import the CRL on a regular basis.

Have the administrator demonstrate the configuration setting that enables CRL checking in the event the OCSP server is not available.

If the application is not configured to implement a CRL, this is a finding.
