A new schema for security in dynamic uncertain environments

It is our hypothesis that for a complex system of systems operating in a dynamic, uncertain environment the traditional approach of forward, static security is insufficient. What is required are macroscopic schemata for security that incorporate mechanisms which monitor the overall environment and feed their observations back into the security mechanisms so that they can adjust their ‘posture’ accordingly. Such schemata must also account for system-wide aggregated security risks in addition to risk presented by the individual users and information objects. We propose one such schema in this work.
