Vulnerability Discussion

To ensure accountability, prevent unauthenticated access, and prevent misuse of the system, nonprivileged users must use multifactor authentication for local access.

Multifactor authentication is defined as: Using two or more factors to achieve authentication.

Factors include:
(i) Something a user knows (e.g., password/PIN);
(ii) Something a user has (e.g., cryptographic identification device, token); or
(iii) Something a user is (e.g., biometric).

A nonprivileged account is defined as an information system account with authorizations of a regular or nonprivileged user.

Local access is defined as access to an organizational information system by a user (or process acting on behalf of a user) communicating through a direct connection without the use of a network.

Applications integrating with the DOD Active Directory and using the DOD CAC are examples of compliant multifactor authentication solutions.

Check

If the Mainframe Product has no function or capability for user logon, this is not applicable.

If the Mainframe Product employs an external security manager for all account management functions, this is not applicable.

Examine user account management configurations.

If the Mainframe Product is configured to require multifactor authentication for local access to nonprivileged accounts, this is not a finding.

Fix

Configure the Mainframe Product account management settings to require multifactor authentication for local access to nonprivileged accounts.
