1 Trusted Ring: A Security Enhancing Software Architecture Michael DiRossi, Inventor The Johns Hopkins University Applied Physics Laboratory

2 Technology Problem Space Windows and Linux computers can not be trusted for high assurance applications because they are too complex to secure or verify –Monolithic kernel design –Bug in mouse driver compromises entire system –OS can not protect itself Users want to use these systems Can a high assurance computing environment be built with low assurance components?

3 Technology – Trusted Ring Framework Security enhancing software architecture that –is independent of OS –supports security service modules –provides a high assurance base from which to assert that desired security properties hold true –is based on hardware protection mechanisms

4 Technology – Security Service Modules Security Services enhance the security of the operating system Operate in an execution domain that is independent of and isolated from the operating system Examples: –Platform self-healing capability –Protected encryption engine for online banking

5 Technology Applications Information Assurance –Security policy can be enforced despite compromises to the integrity of the operating system General purpose high assurance computing platforms Complimentary to virtualization technologies –Enhance security from within a VM –Enhance security of VMM

6 Commercial Applications Any Intel IA-32 computer application with IA requirements –Banking –SCADA –Government –Electronic Voting Technology Readiness –Proof-of-concept Trusted Ring Framework implementation for a Fedora Core 1 Linux operating system –Basic self-healing security service implementation
