With SSL VPN Overhead Construction Enterprise Information System

The development of SSL VPN to the existing SSL application is a supplement, it increased the company to carry out the access control and the safe rank and the ability. SSL VPN also have the help to there enterprise which reduce the company's secure enterprise because of uses the long-distance access application system. In the subordinate says, the digit dialing may guarantee the relative security, because the specific telephone line may confirm the user the status. The C/S system and old edition VPN oneself also has the certain rank the safety control ability, because customer end software is needs to install. But, by such security policy and the attribute, incontestable, the hacker invades, the safe threat, the status cheat assumes the growth tendency. Now, used SSL VPN, the security feature has already had the change, the people may through the browser visit application procedure.SSL VPN's value including many aspects, most main sharpens the access control ability, the security, easy to use and the high investment repayment rate.Access control of SSL VPN is more effective to the access control, because it has implemented the user centralization management. All long-distance access all are control bench carry on through SSL VPN control the tube, so that it can monitor user use authorities more effective, these users possibly be the company interior staff, the partner or the customer. All access are limited in the application level, moreover may subdivide the authorities to URL or a document.But uses IPSec VPN, the authorities of security only limit the network.SSL VPN does not need the complex client software, this is easy to install and the disposition, obviously reduces the cost. IPSec VPN needs in a remote terminal user installment specific equipment, to establish the security pipe, moreover in very many situations (or non-enterprise controls) in the equipment in exterior to establish the pipe to be quite difficult. Moreover, this kind of complex client software are difficulty with promotes. To the new user said faced with the trouble are possibly more, like system support question, time expenses question, and management question and so on. IPSec VPN's solution initial cost lower, but the movement strut cost is high. Now, had the SSL developer to be able to provide the network layer support, carries on the network application access, is similar to the long-distance machine to be in LAN to be same; simultaneously provides application layer turns on, carries on the Web application and many C/S applications access.In brief, it is proven this technical maturation and the reliability in the essential duty environment. SSL VPN will play the role in the enterprise application which will not have may estimate. But to enterprise which does not have the specialized technical personnel, deployed the use regarding is too difficult. And the cost question also is restricts the enterprise a important reason.I designed and realized this kind of soft SSL VPN system in this article. This system is an inexpensive even free system, most importantly moreover this system also is advantageous for the deployment to be advantageous for management SSL VPN system. The administrative personnel only needs to have general SSL VPN knowledge then to carry on the installment (to be similar to general Windows software installation procedure) and the deployment, simultaneously has the standard the Windows graphical interface to use in to manage SSL VPN system.Below this article research content mainly had several aspects: Research at present in world popular SSL VPN concept and content, designs to suit mid- and small-scale enterprise China, specially mid-and small-scale enterprise China which can withstand in the installment deployment maintenance the SSL VPN network system.Research at present international center newest opens source project OpenSSL and OpenVPN, uses these two open source project code, constructs soft SSL VPN system.Finally unifies above two achievements, specifically founds standard Windows software to use in to manage and config SSL VPN system. This is a standard Windows graphical interface software, manages and config SSL VPN system to be extremely simple, it is advantageous for the ordinary system administration personnel to maintain manages SSL VPN system.
