Excerpt: Security-Enhanced Linux (SELinux) is a Linux feature that provides the mechanism for supporting access control security policies, including United States Department of Defense-style mandatory access controls, through the use of Linux Security Modules (LSM) in the Linux kernel. It is not a Linux distribution, but rather a set of kernel modifications and user-space tools that can be added to various Linux distributions. Its architecture strives to separate enforcement of security decisions from the security policy itself and streamlines the volume of software charged with security policy enforcement. The key concepts underlying SELinux can be traced to several earlier projects by the United States National Security Agency. It has been integrated into the mainline Linux kernel since version 2.6, on 8 August 2003. The United States National Security Agency (NSA), the original primary developer of SELinux, released the first version to the open source development community under the GNU GPL on December 22, 2000. The software merged into the mainline Linux kernel 2.6.0-test3, released on 8 August 2003. Other significant contributors...
