The Flux Advanced Security Kernel (FLASK) is an operating system security architecture that provides flexible support for security policies. FLASK is a core framework in security-focused operating systems such as NSA's Security-Enhanced Linux, OpenSolaris FMAC and TrustedBSD. This means that SELinux can be thought of as an implementation of FLASK.
