Research And Implementation Of Security Remote Supervision Platform Based On VPN Technology

In order to maintain the security and stability of campus, to ensure the normal teaching order, to create a "safe campus", school leadership attaches great importance to the security guard work, the construction of campus security system has increasingly become an indispensable part of the whole construction in Colleges and universities, has become the whole school to achieve the scientific management of an important measure and means necessary. How to manage the campus security system effectively, so that the whole security system to really play a role, has become a priority need to consider security construction in Colleges and universities. For security reasons to consider, Fujian University of Technology security system using network is a special network mode to the security center. But because many regulatory requirements, school administrators sometimes need to watch the CCTV site monitoring. If directly to the security center to conduct on-site monitoring, low work efficiency. If directly through the campus network stressed at the scene monitoring, will produce the monitoring image return slowly, control failure hand does not guarantee in network bandwidth condition; on the other hand, the security network security will also bring hidden trouble. To effectively solve the above problem, this paper design and implement a VPN based technology of campus security remote monitoring platform, realize the remote supervision of campus security video surveillance system. Has brought great convenience for the management and use, play an important role in enhancing safety campus.The paper describes in detail how to in campus network and security network set up a virtual special net based Linux (VPN) remote dial in system, through the point to point Tunneling Protocol (PPTP) of the tunnel technology, build the virtual private network in the campus network, the realization of safe, quick stressed at the scene monitoring. Connection encrypted tunnel using VPN technology to provide reliable, safe, using 128 bit network communication encryption system to ensure the safety and security center, and to provide Microsoft point to point compression protocol based on data compression problem, improve the network transmission rate to prevent the campus net network bandwidth does not guarantee the situation produces monitoring image back slowly, control failure.Design and Realization of dial in user management system and dial in server status monitoring system based on the VPN dial in server, realize the effective management and monitoring of VPN remote dial in the state of the system on the dial in VPN users, a variety of state administrators only need to open the Webpage can effectively manage, dial in users quickly and easily to view the VPN remote dial in system server, instead of using fussy order.VPN technology is currently the campus security remote monitoring platform based on the function has been achieved, the results show that the designed scheme of the system is reasonable and feasible measures to solve the problem.
