Fix Recommendation

Configure the operating system to do certificate status checking for PKI authentication.

Modify all of the "cert_policy" lines in "/etc/pam_pkcs11/pam_pkcs11.conf" to include "ocsp_on".

Check Contents

Verify the operating system implements certificate status checking for PKI authentication.

Check to see if Online Certificate Status Protocol (OCSP) is enabled on the system with the following command:

# grep cert_policy /etc/pam_pkcs11/pam_pkcs11.conf | grep -v "^#"

cert_policy = ca, ocsp_on, signature;
cert_policy = ca, ocsp_on, signature;
cert_policy = ca, ocsp_on, signature;

There should be at least three lines returned.

If "ocsp_on" is not present in all uncommented "cert_policy" lines in "/etc/pam_pkcs11/pam_pkcs11.conf", this is a finding.
