OL 8 file systems must not interpret character or block special devices that are imported via Network File System (NFS).

Rule version OL08-00-010640 · STIG v2 · 2026-08-24

Discussion

The "nodev" mount option causes the system to not interpret character or block special devices. Executing character or block special devices from untrusted file systems increases the opportunity for nonprivileged users to attain unauthorized administrative access.

Check

Note: If no NFS mounts are configured, this requirement is Not Applicable.

Verify file systems being imported via NFS are mounted with the "nodev" option with the following command:

$ sudo grep nfs /etc/fstab | grep nodev 

UUID=e06097bb-cfcd-437b-9e4d-a691f5662a7d /store nfs rw,nosuid,nodev,noexec 0 0

If a file system found in "/etc/fstab" refers to NFS and it does not have the "nodev" option set, this is a finding.

Fix

Configure the "/etc/fstab" to use the "nodev" option on file systems that are being imported via NFS.
