Vulnerability Discussion

The use of PIV credentials facilitates standardization and reduces the risk of unauthorized access.

The DoD 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.

Check

Verify RHEL 8 accepts PIV credentials.

Check that the "opensc" package is installed on the system with the following command:

$ sudo yum list installed opensc

opensc.x86_64 0.19.0-5.el8 @anaconda

Check that "opensc" accepts PIV cards with the following command:

$ sudo opensc-tool --list-drivers | grep -i piv

PIV-II Personal Identity Verification Card

If the "opensc" package is not installed and the "opensc-tool" driver list does not include "PIV-II", this is a finding.

Fix

Configure RHEL 8 to accept PIV credentials.

Install the "opensc" package using the following command:

$ sudo yum install opensc
