1. Overview
1. What is Security-enhanced Linux?
Security-enhanced Linux (SELinux) is a reference implementation of the Flask security architecture for flexible mandatory access control. It was created to demonstrate the value of flexible mandatory access controls and how such controls could be added to an operating system. The Flask architecture has been subsequently mainstreamed into Linux® and ported to several other systems, including the Solaris™ operating system, the FreeBSD® operating system, and the Darwin kernel, spawning a wide range of related work. The Flask architecture provides general support for the enforcement of many kinds of mandatory access control policies, including those based on the concepts of Type Enforcement®, Role-based Access Control, and Multi-level Security.
