On Computer Network Security and Preventive Measures

With the wide application of computer network in the field of human life, the attacks against computer network are increasing day by day. The Internet has influenced the politics, economy, culture, military affairs, ideology and social life of societies all over the world. At the same time, on a global scale, the number of intrusions and attempted intrusions against important information resources and network infrastructure continues to increase, and cyber attacks and intrusions pose a great threat to national security, economy and social life. Computer viruses are constantly produced and spread through the network, computer networks are constantly illegally invaded, important information and data are stolen, and even the network system is paralyzed. Such incidents have caused great losses to the government and enterprises, and even endangered national security. Network security has become the focus of attention all over the world, and the importance of network security is self-evident. Therefore, it is more important to understand and guard against loopholes. In this paper, I will comprehensively summarize some past and existing network and system vulnerabilities, explain several common and latest vulnerabilities and their characteristics in detail, and further introduce preventive measures against these vulnerabilities, so that everyone can understand and understand the harm of these vulnerabilities and better protect their computers. Computer Network Technology/Computer Network Security/Security Vulnerabilities: On the security vulnerabilities of computer networks and preventive methods Abstract: With the popularization of computer networks in Hu. In the field of human life, attacks against computer networks have also increased. The influence of network on politics, economy, culture, military affairs, ideology and social life is everywhere. At the same time, on a global scale, the number of intrusions and intrusion attempts against important resources and network infrastructure equipment is increasing. Network attacks and intrusions pose a great threat to national security, economy and social life. Computer viruses are constantly produced and spread; The computer network has been illegally invaded; Important information and data are stolen, and even the network system crashes. Such incidents have caused great losses to the government and enterprises, and sometimes even endangered national security. Therefore, network security has become the focus of attention all over the world, and its importance is self-evident. Therefore, it is important to understand computer vulnerabilities and preventive measures. In this paper, some existing network and system vulnerabilities and vulnerabilities that have been used are summarized, some common and emerging vulnerabilities and their characteristics are explained in detail, and the prevention methods of these vulnerabilities are further introduced, in order to let everyone know and understand the harm of these vulnerabilities, so as to better protect their computers.
