| Description | ||||
| 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 in use by the organization helps to prevent users from using unauthorized smart cards.

Check Text (C-258121r1102086_chk)
Verify that RHEL loads the CAC driver with the following command:
$ sudo opensc-tool --get-conf-entry app:default:card_drivers cac
cac
If "cac" is not listed as a card driver, or no line is returned for "card_drivers", this is a finding.
Fix Text (F-61786r1045242_fix)
Configure RHEL 9 to load the CAC driver.
$ sudo opensc-tool --set-conf-entry app:default:card_driver:cac
Restart the pcscd service to apply the changes:
$ sudo systemctl restart pcscd
