Fix Recommendation

Modify "/etc/fstab" to use the "nosuid" option on the "/var/log/audit" directory.

Check Contents

Verify "/var/log/audit" is mounted with the "nosuid" option:

$ mount | grep /var/log/audit

/dev/mapper/rhel-var-log-audit on /var/log/audit type xfs (rw,nodev,nosuid,noexec,seclabel)

If the "/var/log/audit" file system is mounted without the "nosuid" option, this is a finding.
