Self-Adaptive End-Point Mutation Technique Based on Adversary Strategy Awareness

Abstract

Moving target defense is a revolutionary technology to change the pattern of attack and defense, and end-point information mutation is one of the hotspots belonging to this field. In order to counterpoise the defense benefit of end-point information mutation and service quality of network system, the self-adaptive end-point mutation technique based on adversary strategy awareness is proposed. Directed at the blindness problem of mutation mechanism in the course of defense, adversary strategy awareness based on Sibson entropy algorithm is proposed for guiding the choice of mutation mode by discriminating the scanning attack strategy. Aimed at the low availability problem caused by limited network resource and high mutation overhead, satisfiability modulo theories are used to formally describe the constraints of mutation. Finally, theoretical and experimental analysis shows the ability to resist scanning attack and mutation overhead.
