Design And Implementation Of An Enterprise Computer Network Security System

The idea and method of multi hiberarchy design for security is proposed in thispaper with the basic theory of security for modern network. A detailed analysis onhiberarchy is done to figure out the potential security risk under various internal levelsof an enterprise by deeply study on a dummy enterprise network. According to theprinciple of “integrity, balance, combination of technology and management”, anetwork security target which is fit for the requirement of enterprise is issued. Andbased on it, a total network security solution is proposed. This article focuses on thesetup of firewall, design and setup of inbreak detection system, implementation of VPNand application of access control program. It also discusses the selection, setup andmanagement system of the network hardware. This solution has a lot of advantages,such as high practicability, strong security, good performance-to-price ratio, easilyexercisable, advanced setup and well extensibility.
