Analysis of Computer Network Security and Prevention Technology

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