    If a must-have, must-know innovation exists for Linux's future viability, you might place all bets on Security Enhanced Linux. Vastly misunderstood and underrated, SELinux provides a marketing differentiator that could carry Linux deep into infrastructures that so far have shown lukewarm acceptance of the open-source operating system. SELinux transforms standard Linux from a cost-effective and secure operating system into a behemoth.

    In December 2000, researchers at the U.S. National Security Agency (NSA) working with Network Associates and MITRE released a B1 Class operating system to the public known as SELinux. Although many Linux professionals have heard of SELinux, few recognize that its heritage reaches back to the work of David Bell and Leonard LaPadula, work begun in 1973. Bell and LaPadula's work helped define the criteria that make up the U.S. Government's Trusted Computer System Evaluation Criteria (TCSEC).

    Four years after the release of SELinux, several Linux distributors, Red Hat, SUSE, Debian GNU/Linux and Gentoo Linux, finally have announced plans to support it.
