Computer Network Security Hazards and Preventive Strategies

Abstract

In people’s application of computer network, the management of computer network security becomes more and more important. At the same time, there are huge hidden dangers. Whether the computer is on the system or on network security, there are more or less vulnerabilities. These loopholes and advantages are gradually being exploited by viruses spread on the network, which not only bring to human life. It has caused great distress and has become a major threat to computer security. In the context of the new era, it is even more important to strengthen solutions to computer network security risks. The purpose of this article is to support the protection of computer network security through research and analysis of this theoretical and practical research. This article uses the DCFW1800 series firewall. Users can customize such firewalls to selectively enter data and filter. Configure the network based on the user’s personal needs and set up what needs to be blocked and allowed. After the firewall is defined, it is filtered based on the configured data flow to meet the needs of various users. Based on these classifications and their definitions, 46 security risks are classified into three categories. The insecure state of the network, the unsafe behavior of personnel, and management flaws. Experimental results show that the degree of network performance degradation after a single network failure also decreases.
