Remove suid / gid and execute permission for 'group' and 'others'.
Similar to: chmod og-ugx /path/to/filename

Removing execution permission is useful to make binaries such as 'su' fail closed rather
than fail open if suid was removed from these.

Do not remove read access since no security benefit and easier to manually undo for users.

chmod 744
