Dynamic Defensive Posture for Computer Network Defence

摘要

This paper examines the concept of dynamic defensive posture in computer networks. We propose that defensive posture is provided by knowledge of whether and how critical network resources are vulnerable to attack. After introducing the basic concept, we discuss the constituent elements of defensive posture. We then review relevant technologies, finding that current technology addresses only aspects of the problem. Finally, we propose a variety of research problems for which the solutions would contribute significantly to our ability to identify a network's defensive posture.
