Large (medium) Sized Enterprise Network Security System Design And Implementation

This project enterprise is a state-owned large-scale Iron and steel enterprise. Along with the business development, its network platform is already lag, and there have been the serious influence on the company’s long development. The backbone network problems of the company are mainly:The backbone is not divided vlan, the computer can access; it can’t controll Information transferring; it is difficult to trace accident and to locate trouble.The backbone network is no unified Anti-virus solution. It is difficult to timely and effective, acomprehensive statistic and antivirus.For the above problems, we develop the programmes in the project:analysis, research enterprise data flow and flow analysis; design, implementation functions of various (Class) code and value for vlan; design the demand of various vlan ACL control; the connect test vlan with various equipment firms; the cutting test of environmental with main devices and syntaxis equipment; training and submiting a report; eliminating some small problems later.The project implementations are mainly:the overall planning backbone network vlan, separating the vlan into25at least based on the network port, the department of management, network equipment management and video. The solution of the Anti-virus system is center first, division, installing way at the desktop. The centre first is arranging the Anti-virus software for host server in the old room, then arranging a new Anti-virus software for slave servers, finally installing the Anti-virus software on the desktop computer. The solution of safety management is mainly that ensure stability and security of network implementation in the whole project. After the project completed, we will optimize the backbone network management of safety device.The Anti-virus software achieve the management and distribution between the segments, vpn access: achieving focus distribution, virus scanning engine, updating and generating integrate log statements. We have obtained the good results since the project is implemented.
