Fix Recommendation

Configure OL 9 to prevent files with the setuid and setgid bit set from being executed on the /boot directory.

Modify "/etc/fstab" to use the "nosuid" option on the "/boot" directory.

Check Contents

Verify that OL 9 is configured to mount /boot with the nosuid option.

Verify that the /boot directory is mounted with the "nosuid" option with the following command:

$ mount | grep '\s/boot\s'
/dev/sda1 on /boot type xfs (rw,nosuid,relatime,seclabe,attr2,inode64,noquota)

If the /boot file system does not have the "nosuid" option set, this is a finding.
