Rule Text

RHEL 10 must use the common access card (CAC) smart card driver.

Description

Discussion Text

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. 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

SCC Automation Reference

The reconstructed evaluation script behind this rule's OVAL check(s) — every module a compound check combines, with this rule's own concrete values and DISA's SCC tool's real per-module mechanism curated from static teardown of SCC releases.

Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

#!/bin/sh
# OVAL Definition: oval:mil.disa.stig.rhel10os:def:280976

if grep -qE "(?i)^\\s*card_drivers\\s*=(.*);" /etc/opensc.conf && grep -qE "(?i)\\bcac\\b" /etc/opensc.conf; then
    echo "PASS"
    exit 0
else
    echo "FAIL"
    exit 1
fi

Remediation

Configure RHEL 10 to load the CAC driver:

$ sudo opensc-tool --set-conf-entry app:default:card_drivers:cac

Restart the pcscd service with the following command for the changes to take effect:

$ sudo systemctl restart pcscd
