Research On Computer Virus Defense Strategy Based On Network Transmission

What we are now experiencing is the era of rapid development of information technology.Informatization has brought convenience to human beings,and at the same time has brought Internet viruses.As the greatest security hazard in the information age,Internet viruses have used the rapid development of Internet technology to expand rapidly.Therefore,it is an important issue in this field of information security.We need an efficient way to detect and defend against viruses.At present,whether it is in the field of technology or model,the detection and defense methods of computer network viruses do not have the means to detect and defend some new types of viruses.They are mainly governance,and the hysteresis is very serious.In this paper,the main idea of the model based on defense and supplemented by governance is formed,and a virus detection and defense model is established inside the LAN network to overcome this technical problem.The final effect is to approach zero network infection rates and control network viruses outside the network.Virus defense vendors,servers,and clients are the main aspects of this model.Today's network isolation prevention and control methods have a serious impact on network traffic,such as maintaining specially designated subnets for unchanged network addresses.In this paper,on the basis of not isolating all the nodes,the application of computer nodes is isolated separately,and a kind of isolation method based on application type is established,which can effectively eliminate the negative effects of existing isolation methods.As an active virus,the network virus can infect one node in the network without protection,and the rest of the nodes will be infected one after another.This paper studies a network virus transmission early warning system,which can reach the standard of guarding the entire network.This escort form is divided into three parts.The first part first establishes a control center,and the second part uses this global control center to capture the entire network.The third part carries out agreement of the captured message,and the different agreements adopt different treatment methods.In this paper,an active defense model is studied,and a distributed network virus warning system is established.The method is divided into two steps.The first step is to calculate the weight of the monitored program through real-time monitoring.The programs with different weights have different processing methods to choose.They are:waiting for processing,program shutdown,and program adoption;In the second step,in order to certify the credibility and practicality of this mode,it needs to be experimentally proved.At the end of this paper,in order to further improve the early warning system,listed the Internet virus classification standards.
