Description
To assure accountability and prevent unauthenticated access, 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) Non-privileged accounts are not authorized access to the network element regardless of access method. Network access is any access to an application by a user (or process acting on behalf of a user) where said access is obtained through a network connection. Authenticating with a PKI credential and entering the associated PIN is an example of multifactor authentication. This requirement applies to ALGs that provide user authentication intermediary services.

Check Text ( C-55137r1_chk )
If the ALG does not provide user authentication intermediary services, this is not applicable. Verify the ALG is configured to use multifactor authentication for network access to non-privileged accounts. If the ALG does not use multifactor authentication for network access to non-privileged accounts, this is a finding.

Fix Text (F-59375r1_fix)
If user authentication intermediary services are provided, configure the ALG to use multifactor authentication for network access to non-privileged accounts.
