A survey of network defense decision-making methods based on attack defense game

Abstract

Game theory studies the optimal decision-making problem under the condition of conflict confrontation , It is one of the basic theories of Cyberspace Security , It can provide a theoretical basis for solving the problem of network defense decision . Refine the goal opposition of network attack and defense 、 Policy dependency 、 The relationship is not cooperative 、 Incomplete information 、 Dynamic evolution and interest driven 6 There are three aspects of game characteristics . On the basis of human hypothesis and resource limitation hypothesis , Use offensive and defensive players 、 Attack and defense strategy set 、 Attack and defense action set 、 Attack and defense information set and attack and defense revenue formalize a five tuple network attack and defense game model , The existence conditions of game equilibrium are analyzed , Summarize the network defense decision-making process based on the attack defense game model . Combing and analyzing the static game based on complete information 、 Complete information dynamic game 、 Incomplete information static game 、 Incomplete information dynamic game 、 Evolutionary game 、 Differential game 、 Time game and random game are 8 Applicable scenarios of network defense decision-making methods of different types of game models , Summarize its research ideas , Give the advantages and disadvantages of network defense decision-making methods based on different types of game models . Summarize the development process of network defense decision-making method based on attack and defense game , Explain the advantages and characteristics of defense decision-making methods ; It is pointed out that the relationship between game modeling considerations and model complexity is faced in the research process , The dependence of game reasoning on information and data , Generalization and migration of game model 3 A question ; And from the specification
