Verify the operating system disables the ability to automount devices. Check to see if automounter service is active with the following command: Note: If the autofs service is not installed, this requirement is not applicable. $ sudo systemctl status autofs autofs.service - Automounts filesystems on demand Loaded: loaded (/usr/lib/systemd/system/autofs.service; disabled) Active: inactive (dead) If the "autofs" status is set to "active" and is not documented with the Information System Security Officer (ISSO) as an operational requirement, this is a finding. |
