Effectiveness of Moving Target Defenses

摘要: Moving target defenses have been proposed as a way to make it much more difficult for an attacker exploit vulnerable system by changing aspects of that present attackers with varying attack surface. The hope is constructing successful requires analyzing properties the system, and in time takes learn those construct exploit, will changed enough can launch disrupt exploit’s functionality. This promising appealing idea, but its security impact not yet clearly understood. In this chapter, we argue actual benefits moving approach are fact often less significant than one would expect. We model thinking about dynamic diversity defenses, analyze few example attacks, identify scenarios where effective.
