Analysis And Implementation. Xx Enterprise Network Security

The society is changing greatly at present with continuous acceleration of global informatization and swift and violent development of computer networking technology. Global informatization has become mega-trend of modern social development. But because of all kinds of disadvantages existing in the network itself and variety and openness of network interconnection form, network security has become focus of attention of the society and become important and popular field of current information science and technology research.Building network security defence system whose entirety is impeccable has become important solution for solving security problem because all kinds of natural and man-made factors which can menace network security such as earthquake and hacker and so on exist. Specifically it is very important for enterprise whose scale is enlarged continuously, network informatization construction is at primary development stage and network security system is not sound. XX enterprise decides to plan and construct security system for enterprise network in order to develop informatization of enterprise quickly and well, upgrade and improve its current network environment, improve security and reliability of enterprise net and guarantee safe, stable and high-efficient operations of production, management and administration businesses of the enterprise in the situations of whole network and information security at now. This thesis submits network security solution which aims at the enterprise after analyzing and evaluating the network of the enterprise.Firstly, the thesis submits network security solution which aims at the XX enterprise under guidance of information security linkage theory, combining whole development trend of enterprise network security, evaluating and analyzing network topology structure and network security risk condition of the XX enterprise, combining special network security requirement of the XX enterprise and at the condition of reducing cost outlay as much as possible. Secondly, at the condition of according to network security universal design principle, it abundantly applies current advanced network security technologies and products such as firewall/water proofing wall, VPN,IDS/IPS, disaster-tolerant backup and security management measures and also plans scientific and trends harmonious XX enterprise network security solution and strategy. The program has obvious effect in network real application of the XX enterprise and has a definite guidance functions to current network security constructions of medium-sized and small enterprises.The construction of network security system is a long and trends variation process; new network security technical artifices continuously appear but new attack and invasion artifices will appear with that at the same time. Any security system design program can not solve all security problems completely. But with propulsions of enterprise networking and informatization processes, recognition to network security problem in informatization systemic construction will be deepened and improved continuously in management system, theory research and technical development so as to submit feasible program which is better for solving network security problem.
