My collection of SELinux resources. Click away.

SELinux Overviews and Reviews
- Security-Enhanced Fedora Core 2 a brief article at LWN.net on Fedora Core 2 and its SELinux 2.6 kernel.

- "SPY-NUX" Update Interesting article from the Information Security magazine by Pete Loshin.
- An Overview of Security Enhanced Linux A Kuro5hin article giving a quick and simple technical overview. A little out-dated.
- Uncovering the secrets of SE Linux: Part 1 Interesting article by Larry Loeb, who describes NSA's release as "equivalent to the Pope coming down off the balcony in Rome, working the crowd with a few loaves of bread and some fishes, and then inviting everyone to come over to his place to watch the soccer game and have a few beers". Part 2 is here.
- NAI Labs SELinux Brief (PDF) A 2-page PDF by Stephen Smalley of NAI Labs about SELinux.

- Mandatory Access Control: Silver Bullet or Kafkaesque Nightmare? Part1 of an article on ITWorld.com by Jamie Reid. Part2 is here.
- An Introduction to Role-Based Access Control Interesting paper from NIST on RBAC. A bit old, but still good.
Papers on FLASK ( Flux Advanced Security Kernel )FLASK is the precursor to SELinux, basically it formed a proof of concept whereas SELinux became a more acceptable practical application of the architecture.
- Flask: Flux Advanced Security Kernel Stephen Smalley of NAI Labs describes the FLASK architecture.
SELinux Code and policy sources
- Russell Coker's SELinux archive Russell is one of the SELinux gurus out there. His archive contains up-to-date policy definitions and SELinux-aware applications. He also maintains the SELinux Debian packages.
- Tom Vogt's mirror of Russell's Debian packages. Based in Europe so probably has faster access. Includes APT packages.
