Network Security Protection System Design And Implementation

With the process of in-depth information and the rapid development of internet, people's work, study and life style is undergoing great changes, greatly improve work efficiency, the information resources are greatly shared. But we must see, followed by information developed from the network security issues have become increasingly serious, if this problem is not solved, it will hinder the process of information development.The complexities, variability of network environment, vulnerability of information system, determine the objective existence of network security threats. China's increasingly open and integrated into the world. But to strengthen security supervision and create a protective barrier is indispensable. Information security is a major issue which is related to China's economic development, social development and national security. In recent years, with the development of the international political situation, and speed up the process of economic globalization, people is becoming increasingly clear, information security problem caused by information time is not only involve country's economic security, financial security, but also involve national security, political security, cultural security. So, it can be said, in the information society, without the protection of information security, there is no barrier to national security. The importance of information security can never emphasize too much.The security system's goal is, relying on the existing WAN covering the center of Sichuan Province, to ensure data transfer and internal network security between the provincial bureau and city (state) bureau,182 counties (districts) stations. In addition, provincial bureau uses network control platform for centralized monitoring, decentralized management of city bureau's servers, business applications and WAN equipment.The security system is closely to the goal of building a secure and available information network. To use advanced networking technology, supported by reliable network information security technology, accelerate the process of bureau's information, ensure system environment and equipment safety, prevention unauthorized access to information resources, resist illegal theft of classified information, protect safety of data assets, increase bureau's systems comprehensive support capabilities in complex application environments.
