Discussion

Without identifying devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. Peripherals include, but are not limited to, such devices as flash drives, external storage, and printers. Satisfies: SRG-OS-000114-GPOS-00059, SRG-OS-000378-GPOS-00163

Check Content

Note: If the "autofs" service is not installed, this requirement is not applicable.

Verify RHEL 10 is configured so that the file system automount function has been disabled with the following command:

$ systemctl is-enabled  autofs
not-found

If the returned value is not "masked", "disabled", or "not-found", this is a finding.

Fix Text

Configure RHEL 10 to disable the ability to automount devices.

The "autofs" service can be disabled with the following command:

$ sudo systemctl mask --now autofs.service
