Toward Proactive, Adaptive Defense: A Survey on Moving Target Defense
Reactive defense mechanisms, such as intrusion detection systems, have made
significant efforts to secure a system or network for the last several decades.
However, the nature of reactive security mechanisms has limitations because
potential attackers cannot be prevented in advance. We are facing a reality
with the proliferation of persistent, advanced, intelligent attacks while
defenders are often way behind attackers in taking appropriate actions to
thwart potential attackers. The concept of moving target defense (MTD) has
emerged as a proactive defense mechanism aiming to prevent attacks. In this
work, we conducted a comprehensive, in-depth survey to discuss the following
aspects of MTD: key roles, design principles, classifications, common attacks,
key methodologies, important algorithms, metrics, evaluation methods, and
application domains. We discuss the pros and cons of all aspects of MTD
surveyed in this work. Lastly, we highlight insights and lessons learned from
this study and suggest future work directions. The aim of this paper is to
provide the overall trends of MTD research in terms of critical aspects of
defense systems for researchers who seek for developing proactive, adaptive MTD
mechanisms.Comment: 36 pages, 15 figure
