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 discussed. Through the description and analysis of the existing system of network within an secrete enterprise , from the point of view of the structure the possible security loopholes and security risk are analysis 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.
