Description
To assure accountability and prevent unauthenticated access, privileged and non-privileged users must utilize multifactor authentication to prevent potential misuse and compromise of the system. Multifactor authentication uses two or more factors to achieve authentication. Factors include: 1. Something you know (e.g., password/PIN); 2. Something you have (e.g., cryptographic identification device, token); and 3. Something you are (e.g., biometric). The DoD CAC with DoD-approved PKI is an example of multifactor authentication.

Check Text ( C-92261r1_chk )
Verify the global "auth_type" is configured to use PAM: # grep auth_type /etc/security/login.cfg \|grep AUTH auth_type = PAM_AUTH If "auth_type" is not set to "PAM_AUTH", this is a finding. Verify that the user stanza is configured to use PAM: # lssec -f /etc/security/login.cfg -susw -a auth_type usw auth_type=PAM_AUTH If "auth_type" is not set to "PAM_AUTH", this is a finding.

Fix Text (F-99189r1_fix)
Run the following command to set the global and user stanza "auth_type": # chsec -f /etc/security/login.cfg -susw -a auth_type=PAM_AUTH
