Research On Security Measurement Of Continuous Time Markov Industrial Internet

The industrial Internet is the product of the combination of industrial production and the Internet.It is an open and global network.It has broken the traditional industrial production system relatively closed environment,so that it is inevitable to face the Internet virus,hackers and other security threats.In recent years,a variety of industrial network security incidents have presented explosive growth,causing great economic losses and security threats to enterprises and the society.Therefore,it is urgent to carry out research on the measurement of industrial Internet security.Based on the analysis of the special needs of industrial Internet security,this paper uses multi-state Markov theory to construct Markov security evaluation model and quantitative calculation method according to the characteristics of industrial Internet.Researched the realization technology of the Industrial Internet,analyzed its architecture,and explored the use of polymorphism theory to construct the security random process model of the Industrial Internet from different sides according to the characteristics of the Industrial Internet.Facing the complicated internal and external security situation,the security protection system and strategy of the industrial Internet are proposed with reference to the security level requirements,and finally a polymorphic continuous time Markov security measurement method is proposed.When the Industrial Internet is under attack,failure or accident,there are many factors that cause system service failure.It may be miss operation or attack,it may be software and hardware failures at runtime,or it may be a natural factor.This paper introduces a general generating function to solve the problem of the state explosion of the model,uses Howard differential equations to quantitatively calculate the security of different levels of the system,and proposes the structural equation of the industrial Internet system through the generating function theory to calculate the security of the whole and different levels of the system.Industrial Internet systems are characterized by clear system boundaries,relatively stable network structure,and single network system sovereignty.Aiming at the severe security situation and the essential characteristics of polymorphism,this paper proposes a security attribute perception method for industrial Internet systems.This method can provide theoretical basis for the design of industrial Internet system and the transformation of traditional industrial Internet system.
