From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Clearly you know of lot about this. Here are some comments for the next human.
Deny all modules seems more possible than a whitelist approach. To deny all, the command is likely "sysctl kernel.modules_disabled=1".
Whitelisting is harder. One could store a list of all loaded modules on a working system. Store a list of all kernel modules currently installed on the system. Compare the lists and remove from the "all" list the "running" list (grep will do this) and write it to the blacklist file.
The problem with the Whitelisting approach is that it needs to run after every kernel module install (which is doable).
If the above is the case, then someone must have automated this already, but I cannot find it quickly. (I checked Debian's package repository.)
