TOMOYO Linux is a Mandatory Access Control (MAC) implementation for Linux that can be used to increase the security of a system, while also being useful purely as a system analysis tool. It was launched in March 2003 and is sponsored by NTT DATA Corporation, Japan.
For more information, please visit our project page.
For those "tough guys", TOMOYO Linux just runs fine on LFS. Find yourself and make your own version.
