Some in the security industry say that Linux is inherently insecure, that the way Linux enforces security decsions is fundamentally flawed, and the only way to change this is to redesign the kernel. Fortunately, there are a few projects aiming to solve this problem by providing a more robust security model for Linux by adding Mandatory Access Control (MAC) to the kernel.

The most well-known of these projects is Security Enhanced Linux (SELinux), which was developed by the U.S. National Security Agency (NSA). The Rule Set Based Access Control (RSBAC) project, the Linux Intrusion Detection System (LIDS), and grsecurity are other popular projects with the same goal. All of these projects are open-source and licensed under the GPL.
