Today, the modern computer network develop at full speed, let enterprise to be unable to diverge from computer network and security. Already, the online security issue benefit outstanding too, how about be while guaranteeing development of business, fully spend the open network environment especially nearly having new virus that emerges on Internet every day, the junk email overflows, it is impossible to defend that the hacker attacks.

The purpose of this document is hoped to improve and improve the security of the Intranet network through technology and management.In order to reach the above purposes, this document introduces the company's already existing network. Based on this network, make a large number of user's needs analyze, discuss problem that Intranet appear. Then against different problems, put forward viruses prevention, junk mails filtering, Setting firewall, data back up. And visit the detailed solution which control respects such as the authority, etc. separately. Solution include from system person who select, software and hardware content of structure, administrative structure, etc.Also, This document has also explained the concrete implementation course of all solutions in detail. Through the implementation of scheme, have solved the security problems of several respects described above fundamentally. Between these solutions is not each independently, all schemes should merge, complement each other., If we wnt to achieve our purpose only by stopping up all of loopholes.During putting if practice, I also makes a simple analysis on the development trend of online security. And, we hope the security performance of enterprise's Intranet gets further improvement.
