OL 9 must mount /var/log/audit with the nosuid option.

The "nosuid" mount option causes the system to not execute "setuid" and "setgid" files with owner privileges. This option must be used for mounting any file system not containing approved "setuid" and "setguid" files. Executing files from untrusted file systems increases the opportunity for nonprivileged users to attain unauthorized administrative access.

Verify that OL 9 is configured to mount /var/log/audit with the nosuid option.

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

$ mount | grep /var/log/audit /dev/mapper/ol-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.

Configure OL 9 to mount /var/log/audit with the nosuid option.

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