Title
RHEL 10 must use the common access card (CAC) smart card driver.
Control
Verify RHEL 10 loads the CAC driver with the following command: $ sudo opensc-tool --get-conf-entry app:default:card_drivers cac If "cac" is not listed as a card driver, or no line is returned for "card_drivers", this is a finding.
Discussion
Smart card login provides two-factor authentication stronger than that provided by a username and password combination. Smart cards leverage public key infrastructure to provide and verify credentials. Configuring the smart card driver helps to prevent the use of unauthorized smart cards.
