| 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-215439r991589_chk)
Verify /etc/security/pmfa/pam_pmfa.conf is configured correctly.
# grep -i "trustedcas" /etc/security/pmfa/pam_pmfa.conf | grep -v '#'
TRUSTEDCAS = /<path_to_file>/server_ca.pem
Note: Verify with the SA/ISSO as to the location of the "server_ca.pem" file.
If "TRUSTEDCAS" is not configured to point to a valid "server_ca.pem" file or is missing, this is a finding.
# grep -i "mfa-url" /etc/security/pmfa/pam_pmfa.conf | grep -v '#'
MFA-URL = https://pmfa.example.com:6793/policyAuth/
If the "MFA-URL" is missing or does not point to a valid address, this is a finding.
# grep -i "server-version" /etc/security/pmfa/pam_pmfa.conf | grep -v '#'
SERVER-VERSION = 2
If "SERVER-VERSION" is missing or is not set to "2", this is a finding.
# grep -i "ctc-prompt" /etc/security/pmfa/pam_pmfa.conf | grep -v '#'
CTC-PROMPT-ONLY = Y
If "CTC-PROMPT-ONLY" is missing or is not set to "Y", this is a finding.
Fix Text (F-16635r294769_fix)
Add or update the following lines in the "/etc/security/pmfa/pam_pmfa.conf" file:
TRUSTEDCAS = /<path_to_file>/server_ca.pem
Note: Verify with the SA/ISSO as to the location of the "server_ca.pem" file.
MFA-URL = https://pmfa.example.com:6793/policyAuth/
SERVER-VERSION = 2
CTC-PROMPT-ONLY = Y
