Analysis of Computer Network Security and Prevention Technology

Abstract

: This paper mainly studies computer network security and firewall technology, discussing the functions, main technologies, configurations, security measures, and firewall design ideas of network firewall security technology. With the popularization of computer networks, network security issues are receiving increasing attention from people. We can propose corresponding measures to address the shortcomings and vulnerabilities in current network security and firewall settings, in order to expect our network to be more secure. In terms of ensuring network security and data security, there are data encryption technology, smart card technology, firewall technology, etc. We mainly study firewall technology here. Firewalls can be divided into various types based on their different methods, precautions, and priorities. Afterwards, two basic implementation technologies, firewall packet filtering and application proxy, were introduced. Firewall technology is still in the development stage, and there are still many problems that need to be solved.
