Network admission control system and method for bypass deployment

Abstract

The invention provides a bypass deployed network access control system. The system comprises terminal equipment, a switch and access control equipment. The terminal equipment and the switch establish a session link, the access control equipment is placed on a mirror port of the switch, an inspection module and a communication module are arranged in the terminal equipment, the inspection module is used for inspecting the safety condition of user information and the terminal equipment to generate a safety signal, the communication module is coupled with the inspection module and used for responding to the safety signal to generate a leading package and establish the session link between the terminal equipment and the switch, and a verification module is arranged in the access control equipment and used for responding to the leading package to allow the terminal equipment generating the leading package to have access to a private network. The bypass deployed network access control system and method are deployed to data exchange through a bypass, network data flow of a protected area is monitored, and the illegally connected terminal equipment is skipped or blocked under the condition of not affecting an original user network structure.

Description

technical field [0001] The present invention relates to the technical field of network admission control, in particular to a network admission control system and method for bypass deployment. Background technique [0002] The rapid development of information technology has vigorously promoted the wide application of computer networks and information systems in governments, enterprises and institutions, and provided a solid guarantee for the electronization, automation and informatization of office and production construction. In the government private network (public security, procuratorate, court, government, finance and taxation, electric power, etc.), the network environment is huge and complex. Whether the network equipment connected to the network is safe and reliable, and whether it is allowed to access the network has become an urgent need for information security. solved problem. [0003] At present, there are mainly the following network access control technologies...
