Title

RHEL 10 must disable file system automount function.

Control

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.

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
