Fix Recommendation

Configure the SUSE operating system "/etc/fstab" file to use the "nosuid" option on file systems that are being exported via NFS.

Check Contents

Verify SUSE operating system file systems that are being NFS exported are mounted 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.
