Fix Recommendation

Configure RHEL 10 to mount "/tmp" with the "nosuid" option.

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

To reload all implicit mount units and update the dependency graph so that new options will apply correctly at next remount, run the following command:

$ sudo systemctl daemon-reload

Use the following command to apply the changes immediately without a reboot:

$ sudo mount -o remount /tmp

Check Contents

Verify RHEL 10 is configured so that "/tmp" is mounted with the "nosuid" option:

$ mount | grep /tmp
/dev/mapper/luks-c98555c8-0462-4b97-9afa-6db8c4bfee3b on /var/tmp type xfs (rw,nosuid,nodev,noexec,relatime,seclabel,attr2)

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