Title

Enforce Multifactor Authentication for Login

Control

/usr/bin/grep -Ec '^(auth\s+sufficient\s+pam_smartcard.so|auth\s+required\s+pam_deny.so)' /etc/pam.d/login

Discussion

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 require 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.
