It doesn't enhance security unless additional measures are taken (see
below).

You can use gsecurity (which is in hardened-sources). With
CONFIG_GRKERNSEC_MODSTOP enabled, you will be able to run:
# echo 1 > /proc/sys/kernel/grsecurity/disable_modules
After that, no further modules can be loaded. However, you would also
need to disable privileged I/O and the ability to write to /dev/kmem,
both of which grsecurity also facilitates.
