Attack And Defense

In a real-world network confrontation process, attack and defense actions change rapidly and continuously. The network environment is complex and dynamically random. Therefore, attack and defense strategies are inevitably subject to random disturbances during their execution, and the transition of the network security state is affected accordingly. In this paper, we construct a network security state transition model by referring to the epidemic evolution process, use Gaussian noise to describe random effects during the strategy execution, and introduce a random disturbance intensity factor to describe the degree of random effects. On this basis, we establish an attack-defense stochastic differential game model, propose a saddle point equilibrium solution method, and provide an algorithm to select the optimal defense strategy. Our method achieves real-time defense decision-making in network attack-defense scenarios with random disturbances and has better real-time performance and practicality than current methods. Results of a simulation experiment show that our model and algorithm are effective and feasible.

This paper studies a new network information security system and its evaluation method based on the security threat situation network security model. This paper expounds the application of active defense system and passive defense system in network security, and uses advanced technical support platform and network security model. In this paper, the active defense system and the passive defense system are organically combined to form a new model of computer network security with characteristics. At the same time, based on the idea of security threat situation evaluation, this paper extends the traditional PDRR security model and proposes a network active defense security model and defense in depth security strategy. On this basis, a hybrid architecture of active and passive defense is proposed. The architecture integrates some new network active defense technologies, and constructs a comprehensive and deep network defense system together with network passive defense means. The experimental results show that the proposed defense model improves the security defense efficiency and effective defense rate of the traditional PDRR security model.

this article from the various security threats facing the computer network, systematically introduces the network security technology. And in view of the campus network security issues, firstly analyzes the hidden dangers to the safety of network system in colleges and universities, and then from the build two aspects of security defense system and strengthen the safety management design of the campus network security policy. This paper study, the first thing I learned the main threat to the network security problem, and use the knowledge of security network security problems are analyzed. Secondly, based on the research of the network technology, campus network will also be faced with the security threat. Finally, the idea of established with P2DR model to establish campus network security defense system. And it is concluded that the building of a set of effective network security defense system is the solution Campus network main threats and hidden trouble of necessary ways and measures.

Aiming at the problem that the current generation method of power network security defense strategy ignores the dependency relationship between nodes, resulting in closed-loop attack graph, which makes the defense strategy not generate attack path, resulting in poor defense effect and long generation response time of power network security defense strategy, a generation method of power network security defense strategy based on Markov decision process is proposed. Based on the generation of network attack and defense diagram, the paper describes the state change of attack network by using Markov decision-making process correlation principle, introduces discount factor, calculates the income value of attack and defense game process, constructs the evolutionary game model of attack and defense, solves the objective function according to the dynamic programming theory, obtains the optimal strategy set and outputs the final results, and generates the power network security defense strategy. The experimental results show that the proposed method has good defense effect and can effectively shorten the generation response time of power network security defense strategy.
