Description
Without the use of multifactor authentication (MFA), the ease of access to privileged functions is greatly increased. Multifactor authentication requires using two or more factors to achieve authentication. A privileged account is defined as an information system account with authorizations of a privileged user. The DOD Common Access Card (CAC) with DOD-approved PKI is an example of multifactor authentication. Satisfies: SRG-OS-000375-GPOS-00160, SRG-OS-000105-GPOS-00052

Check Text (C-271607r1091533_chk)

Verify that OL 9 has smart cards enabled in System Security Services Daemon (SSSD) if smart cards are used for MFA with the following command: $ sudo grep pam_cert_auth /etc/sssd/sssd.conf pam_cert_auth = True If "pam_cert_auth" is not set to "True", the line is commented out, or the line is missing, this is a finding.

Fix Text (F-75564r1091532_fix)

Configure OL 9 to enable certificate-based smart card authentication. Edit the file "/etc/sssd/sssd.conf" and add or edit the following line: pam_cert_auth = True
