VPN Technology Application In The Two Campus Network

Along with the Internet technology development, the network in various applications, campus network is more and more bundant large branch, as the Internet in school, especially the college ffice, play an increasingly important role. Various network office oftware and management software application more important role in colleges, universities and colleges in office also more and more without the support of campus network. But with the increase of user groups in the Internet, the importance of network security, and much more obvious the phenomenon of the campus network security to bring greater test.VPN to order in is a use of the Internet or other public Internet Virtual Private Network building proprietary Network security technology, through to the Network data encapsulation and encryption, for users in the public Network established on a temporary, safety transmission tunnel, achieves the special Network security level. The user data through the VPN equipment aunched a logical tunnel, data during transmission is completely encapsulated, at the receiving end the corresponding decryption and authentication technology to confirm the legality of the request launched, thus realize network data transmission in the whole process of safety. Based on two campus visits between network as a background, discusses the existing network security technology and development present situation, the thorough research a virtual private network (VPN) technology and public key infrastructure (PKI) technology basic principle and status quo, puts forward the VPN technology and the way of the combination of the PKI technologyy, design based on the campus network security network architecture VPN, combining the current network model of the status quo and future expansion of demand, may be analyzed in various network business network in practical application, discusses the two campus visits between network of possible security problems, through the deployment of a belt in campus network authentication VPN gateway PKI to solve the problems existing in the campus network security. Finally through in at present more popular Windows2003server operating system, and set up model by the experiment test. Finally, in practical applications of the network security architecture, proves that the model is feasible and has certain practical value.
