Flask: An Operating System Security Architecture The Flask operating system security architecture provides flexible support for security policies. The architecture has previously been implemented in two research operating systems, Mach and Fluke, and is now being implemented in the Linux kernel. http://www.cs.utah.edu/flux/fluke/html/flask.html Utah.edu~Site InfoWhoisTrace RouteRBL Check

Rule Set Based Access Control (RSBAC) for Linux RSBAC is another MAC kernel security enhancement project for Linux. The standard package includes a range of access control models like MAC, RC, ACL. Additionally, the runtime registration facility (REG) makes it easy to implement your own access control http://www.rsbac.de/ Rsbac.de~Site InfoWhoisTrace RouteRBL Check
