Network Security Threat Situation Recognition Based on Attack and Defense Game Model

Abstract

At present, network security is a problem that needs to be solved urgently in the current network era. In order to reduce the loss caused by network security threats, and also use limited computer resources to select the best defense strategy, a set of network attack and defense game models are designed to identify the situation of network security threats. Aiming at the unstable problem of the security quantification process of traditional network node information, a network security threat situation identification based on the offensive and defensive game model is proposed. First, build an offensive and defensive game model, design the corresponding situation identification strategy, and calculate the overall utility and expected output of both offensive and defensive parties while clarifying the changes in the authority of both sides during the offensive and defensive process. This paper takes the offensive and defensive game model as the theoretical basis of the research, uses the algorithm as the auxiliary research, and integrates its important content to analyze and research the optimization of the algorithm to improve the network security threat situation identification. This paper uses the classic offensive and defensive game model as the research object to identify the threat situation of network security. In the process of selecting the offensive and defensive game model, it is necessary to have a better grasp of the relevant algorithms. This article introduces the offensive and defensive game model into the network security threat situation identification, and on this basis, it deeply discusses the applicability and effectiveness of the offensive and defensive game model in the complex network security threat situation identification, and provides better for the establishment of future network security systems. Reference. The experimental results show that this study is effective and feasible in the offensive and defensive game model in the network security threat situation identification. It should be noted that in the defense process, the probability of success and the degree of damage of the attack path must be grasped to ensure that the optimal offensive and defensive decision-making meets the actual needs of network security.
