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 OL 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 OL 8 to accept PIV credentials.
Install the "opensc" package using the following command:
$ sudo yum install opensc
