Description
The system must be configured to enforce multifactor authentication when the sudo command is used to elevate privilege. 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/sudo will be automatically modified to its original state following any update or major upgrade to the operating system.

Check Text (C-268546r1034578_chk)

Verify the macOS system is configured to enforce multifactor authentication for privilege escalation through the sudo command with the following command: /usr/bin/grep -Ec '^(auth\s+sufficient\s+pam_smartcard.so|auth\s+required\s+pam_deny.so)' /etc/pam.d/sudo If the result is not "2", this is a finding.

Fix Text (F-72477r1034577_fix)

Configure the macOS system to enforce multifactor authentication for privilege escalation through the sudo command with the following commands: /bin/cat > /etc/pam.d/sudo << SUDO_END # sudo: auth account password session auth sufficient pam_smartcard.so auth required pam_opendirectory.so auth required pam_deny.so account required pam_permit.so password required pam_deny.so session required pam_permit.so SUDO_END /bin/chmod 444 /etc/pam.d/sudo /usr/sbin/chown root:wheel /etc/pam.d/sudo
