Dedicated Wide Area Network Security Architecture And Design

Since the development of the network, the effectiveness and safety of the network becomes a special problem. Without the way of law and administration, it depends on technical ways in order to protect the safety of the network. Now there are the basic techniques:firewalls techniques, access control techniques,antivirus of the network techniques,network loophole techniques,scanning techniques,IDS techniques,encrpytion techniques of the information,confirmation techniques of the information.In this thesis, the basic modification mechanisms of the professional wide area secure network have been analyzed.After analyzing of the network,we also do some search in the professional wide area secure network.The main results are as follows:Deeply analyzed the safty of the key techniques,such as VLAN techniques,identity attestation techniques,audit techniques,firewalls techniques;It have implemented a detailed system analysis for particular wide area secure network, and finished the design;It has discussed the design and implantation of wide particular secure network in detail.
