Automatically mounting file systems permits easy introduction of unknown devices, thereby facilitating malicious activity.
Satisfies: SRG-OS-000114-GPOS-00059, SRG-OS-000378-GPOS-00163, SRG-OS-000480-GPOS-00227
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.
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.
