Description
The system must be configured to enforce multifactor authentication. All users must go through multifactor authentication to prevent unauthenticated access and potential compromise to the system. IMPORTANT: Modification of Pluggable Authentication Modules (PAM) now requires user authorization or use of a Privacy Preferences Policy Control (PPPC) profile from MDM that authorizes modifying system administrator files or full disk access. NOTE: /etc/pam.d/login will be automatically modified to its original state following any update or major upgrade to the operating system.
