Fix Recommendation

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.

Check Contents

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.
