ℹ️ Check
Verify the operating system disables the ability to automount devices.
Check to see if automounter service is active with the following command:
# 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.
✔️ Fix
Configure the operating system to disable the ability to automount devices.
Turn off the automount service with the following commands:
# systemctl stop autofs
# systemctl disable autofs
If "autofs" is required for Network File System (NFS), it must be documented with the ISSO.
