Design And Implementation Of Network Systems Security

The security of network systems includes physical security, network security, application security and the security management system. The design and implementation of network systems security deals with these problems.In this paper the basic theory and basic knowledge is introduced, the design concept of layered security protection described, and the problems about the establishment and implementation of the network security system discussed. Through the description and analysis of the existing system of network within an enterprise, from the point of view of the structure the possible security loopholes and security risk are analyzed in detail at all levels of its internal network and the practical solution for the network security proposed. This solution has the following characteristics: high reliability, high security, optimum effective-cost, high system application capability, advanced system configuration, good expansion and good operability.The author has read many papers about network security, deeply studied the network information system of an enterprise, made the full exchange of views with experts and put forward the general design concept for the network, participated in the system design of the network security system and organized to implement it, and conducted much management work.
