Fix Recommendation

Modify "/etc/fstab" to use the "noexec" option on the "/home" directory.

Check Contents

Verify "/home" is mounted with the "noexec" option with the following command:

Note: If a separate file system has not been created for the user home directories (user home directories are mounted under "/"), this is automatically a finding, as the "noexec" option cannot be used on the "/" system.

$ mount | grep /home

tmpfs on /home type xfs (rw,nodev,nosuid,noexec,seclabel)

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