Fix Recommendation

Update each NFS mounted file system to use the "nosuid" option on file systems that are being imported via NFS.

Check Contents

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

Verify AlmaLinux OS 9 has the "nosuid" option configured for all NFS mounts with the following command:

$ grep nfs /etc/fstab

192.168.22.2:/mnt/export /data nfs4 rw,nosuid,nodev,noexec,sync,soft,sec=krb5:krb5i:krb5p

If the system is mounting file systems via NFS and the "nosuid" option is missing, this is a finding.
