Fix Recommendation

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

Check Contents

Verify file systems being NFS imported are configured with the "nosuid" option.

Find the file system(s) that contain the directories being exported with the following command:

# more /etc/fstab | grep nfs

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

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

Verify the NFS is mounted with the "nosuid" option:

# mount | grep nfs | grep nosuid
If no results are returned, this is a finding.
