Are there other LSM (Linux Security Modules) in addition to SELinux and AppArmor? In researching this U&L Q&A titled: permission denied for ptrace under GDB, the question came up, "Is there other software similar to SELinux & AppArmor?". User @IwillnotexistIdonotexist mentioned 2 that I'd never heard of: Smack & Yama. He found them by searching through the Linux source code. So now we're up to 4. * SELinux * AppArmor * Smack * Yama Are there others?

In searching for Linux Security Modules, I came across the wikipedia page, titled: Linux Security Modules.

These are the following LSM's listed there:

* SELinux
* AppArmor
* Smack
* TOMOYO Linux
* YAMA LSM
* Linux Intrusion Detection System
* FireFlier
* CIPSO
* Multi ADM



Of the modules listed, the first 4, SELinux, AppArmor, Smack, and TOMOYO Linux are the only ones accepted into the official Linux Kernel, since version 2.6.
