Title

Ubuntu 24.04 LTS must electronically verify Personal Identity Verification (PIV) credentials.

Control

Verify Ubuntu 24.04 LTS electronically verifies PIV credentials via certificate status checking with the following command: $ sudo grep use_pkcs11_module /etc/pam_pkcs11/pam_pkcs11.conf | awk '/pkcs11_module opensc {/,/}/' /etc/pam_pkcs11/pam_pkcs11.conf | grep cert_policy | grep ocsp_on cert_policy = ca,signature,ocsp_on; If every returned "cert_policy" line is not set to "ocsp_on", or the line is commented out, this is a finding.

Discussion

The use of PIV credentials facilitates standardization and reduces the risk of unauthorized access. DoW has mandated the use of the common access card (CAC) to support identity management and personal authentication for systems covered under Homeland Security Presidential Directive (HSPD) 12, as well as making the CAC a primary component of layered protection for national security systems.

Fix

Configure Ubuntu 24.04 LTS to do certificate status checking for multifactor authentication. Modify all of the "cert_policy" lines in "/etc/pam_pkcs11/pam_pkcs11.conf" to include "ocsp_on".
