Maps to IA-2, IA-2(1), IA-2(2), IA-2(3), IA-2(4), IA-2(5), IA-2(8), IA-2(9) via CCI-000764, CCI-000766, CCI-000765, CCI-004045, CCI-001941, CCI-000767, CCI-000768, CCI-000770, CCI-001942

Title

RHEL 9 must use the common access card (CAC) smart card driver.

Control

Verify RHEL 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 in use by the organization helps to prevent users from using unauthorized smart cards. Satisfies: SRG-OS-000104-GPOS-00051, SRG-OS-000106-GPOS-00053, SRG-OS-000107-GPOS-00054, SRG-OS-000109-GPOS-00056, SRG-OS-000108-GPOS-00055, SRG-OS-000112-GPOS-00057, SRG-OS-000113-GPOS-00058
