Fix Recommendation

Configure RHEL 10 to mount "/var/log" with the "noexec" option.

Modify "/etc/fstab" to use the "noexec" option on the "/var/log" 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 /var/log

Check Contents

Verify RHEL 10 is configured so that "/var/log" is mounted with the "noexec" option:

$ mount | grep /var/log
/dev/mapper/luks-c651f493-9fdc-4c6e-a711-0a4f03149661 on /var/log type xfs (rw,nosuid,nodev,noexec,relatime,seclabel,attr2)

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