Vulnerability Discussion

Without the use of multifactor authentication, the ease of access to privileged functions is greatly increased.

Multifactor authentication requires 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 privileged account is defined as an information system account with authorizations of a privileged user.

Network access is defined as access to an information system by a user (or a process acting on behalf of a user) communicating through a network (e.g., local area network, wide area network, or the Internet).

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 network access to privileged accounts, this is not a finding

Fix

Configure the Mainframe Product account management settings to require multifactor authentication for network access to privileged accounts.
