STIG ID: OL08-00-040070 |  SRG: SRG-OS-000114-GPOS-00059 |  Severity: medium |  CCI:  | Vulnerability Id: V-248836

Vulnerability Discussion

Verify the operating system disables the ability to automount devices.

Determine if automounter service is active with the following command:

$ 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.

Check

Configure OL 8 to disable the ability to automount devices.

Turn off the automount service with the following commands:

$ sudo systemctl stop autofs
$ sudo systemctl disable autofs

If "autofs" is required for Network File System (NFS), it must be documented with the ISSO.
