A Survey of Moving Target Defenses for Network Security

Understand

Network defenses based on traditional tools, techniques, and procedures fail to account for the attacker's inherent advantage present due to the static nature of network services and configurations.

• To take away this asymmetric advantage, Moving Target Defense (MTD) continuously shifts the configuration of the underlying system, in turn reducing the success rate of cyberattacks.
• In this survey, we analyze the recent advancements made in the development of MTDs and define categorizations that capture the key aspects of such defenses.
• We first categorize these defenses into different sub-classes depending on what they move, when they move and how they move.
