Study On Perimeter Guard Technology Based On Attack And Defense Strategies

Security technology and precaution industry has formed an extensive application market in China after over 30 years of development.Correspondingly,we are confronted with increasingly severe safety threat.We depend on traditional security precaution mechanism,but such passive defense can no longer meet increasingly complicated security threat.Thus,it is urgent to find out how to actively predict behaviors of offenders.In the meantime,when security precaution system fails to clearly identify the threat,selection of defense strategies will be random and inefficient,which cannot achieve satisfactory defense effect.Therefore,by studying the outermost layer of security precaution in-depth defense system----perimeter,the paper finds out perimeter attack and defense inherently agrees with related principles of game theory.Thus,game theory can be applied to analyze the drill process of perimeter attack and defense.Then we can obtain the most optimized set of attack and defense strategies,so as to predict attack behaviors and to make relevant defense strategies.Previous studies on perimeter guard technology mainly focus on limitation of precaution method itself.They carry out evaluation for perimeter guard system,but description about precaution capacity of perimeter guard system is general.On the basis of traditional analysis method,the paper brings in the dimension of attack,proposes defense strategies toward attack,which enables system users to be clearer about attack behaviors that they can defend.The paper refers to the game theory,which has been increasingly popular in military attack and defense field,as well as network confrontation field.Essentially,perimeter attack and defense confrontation process is a gaming process between attackers and defenders.Related principles of gaming theory can be applied to establish models and to carry out quantitative analysis for attack and defense confrontation process.The paper quantifies costs and benefits of strategies of attackers and defenders,which provides convenience to establish perimeter attack and defense gaming model,and solve Nash equilibrium.Besides,it elaborates on establishment process of perimeter attack and defense gaming model.In the end,the paper carries out case study.By applying perimeter attack and defense gaming theory,it analyzes perimeter attack and defense strategies of universities.According to the final results,we can predict possible attack strategies by the attackers so that perimeter guard system can choose the most suitable defense strategy accordingly.It can provide reference to security precaution system design and its improvement.
