The Programming And Design Of Security VPN Of The Business Enterprise

Thesis author is concerned with the project of security VPN engineering that the unit is a design and practice for the group company. Pass to that item need is with the viability assessment, synthesize consider on the cost performance, technique stability, network safety etc., then designed the solution of a security VPN developments for gathering. After the project is choose through public appraisal, this unit have already the scheme apply to the group company in the network engineering, now, the SVPN system already have being stability moved for several month , and come to the design request.The concept that the text set out, analyze and compared to the VPN is with a few protocol, technique and realizes method under the environment of public information net, and the VPN exists to threaten with the network loophole under the public information net environment. This text still analyzed the Ipsec protocols with applied mechanism in the VPN, and the IPSec is at the problem that puts the item into practice. The thesis put great emphasis on to analyze the usage IPSec protocols to set up the method of the security VPN, discussion for technique realizing method about the related function mold that set up the security VPN with encrypt, distinguish encrypt key exchange and management. On the current market, it analyzed the cost performance of the security VPN equipments, the technique's stability, safety...etc. the foundation of the aspect's factor top, recommended the related equipments with the system mold choosing of piece type. Draw lessons from the advantage of the project of related and security VPN developments, and design the safe solution scheme of the system to gather the way of the large business enterprise network of developments of security VPN technique, on the Internet environment...
