The global information has become the human development trend with the development of network technology. People enjoy the convenience brought by the network technology and confront many network security issues. Because the network attack behavior has concealment, complexity and permeability, the network security issues become increasingly prominent and the network security protection become more difficult. Based on the analysis of the threatening factors to the network security, such as hacking, computer viruses, computer system vulnerabilities, security issues of the network protocol, weak authentication and logic bombs, the firewall technology, intrusion detection technology, access control technology and computer virus protection technology are proposed to ensure safe and stable operation and use of network.

Early network development, people more emphasis on network convenience and availability, and ignore the security of the network. With the development of computer network technology, when people run in the network critical business such as banking, when government activity is increasingly networked, computer network security has become a problem that not allows to ignore. In this paper, the existing network security technology to prevent the analysis and comparison, especially to strengthen security measures should be taken in order to do a more in-depth discussion, and describes the future development trend of this research field.

With the advancement in communication technology, computer network will become important for information exchange. However, the network has the potential therefore the strong security policy is needed for network security ensuring. To prevent the computer network from the virus invasion, the computer network security technology is ensured, having a clear network virus understanding. In this paper, the structural model of network security detection and monitoring system is established in a proactive way, the function of each component is described, and the design model is introduced to conduct comprehensive and effective automatic security detection on the client and each layer of the network, so as to find and avoid the system from being attacked.Result: The observed example shows that the flow rate of information in and out of the network is relatively stable, with few changes, and the rate of change is close to zero per unit time. In the case of network attack, the amount of data flowing into the target network is far more than the amount of data flowing out of the network.Computer security technology is used to improve the security of the network and prevent network virus from attacking the computer network.

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.
