Abstract: Today, when a security incident occurs, the top three questions security administrators would ask are in essence: What has happened? Why did it happen? What should I do? Answers to the first two questions form the core of Cyber Situational Awareness. Whether the last question can be satisfactorily answered is greatly dependent upon the cyber situational awareness capability of an enterprise. In my talk, I will describe a framework to securely operate missions within networks that are imperfect and vulnerable to multiple types of cyber attacks. The key elements of the framework are as follows: First, we introduce the notion of generalized dependency graph which captures how network components, at different levels of abstraction, depend on each other. Second, we extend the classical definition of attack graph to incorporate probabilistic knowledge of the attacker’s behavior. Finally, we introduce the notion of attack scenario graph which integrates dependency and attack graphs.
