Title
The Red Hat Enterprise Linux operating system must disable the file system automounter unless required. (Cat II impact)
Discussion
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
Check Content
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 Text
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.
