Computer Network Security Defense System Design Based on Artificial Intelligence Technology

In the rapid development of the information age, the construction of computer network security protection system is particularly important. Through the analysis of the challenges faced by computer network security defense, such as the diversification of network attack methods, the wide source of network security threats, the diversification of network attack methods, and the imperfect development of network structure, based on the characteristics of artificial intelligence technology and the requirements of the current network security defense system, the overall structure and function of the computer network security defense system are designed. It realizes defense functions such as data collection, analysis and processing of big data, network security protection and evaluation of security protection effect, aiming to maximize the advantages of artificial intelligence technology, so as to enhance the security protection ability of computer networks. Finally, through the experimental test and analysis, the results show that the effective defense information obtained by this method is more than 400bits, which is better than the control group, and has better security defense effect.
