Abstract: Network access control technology can effectively eliminate the threats posed by the insecure endpoints. This paper describes the relevant work of the network access control technology, and according to its realization, it proposes a model of Trusted Network Connect(TNC) based on 802.1X. The authentication flow of network access and the implementation method of endpoint isolation technology are given. Experiment proves that the model ensures the trusted connection of the endpoint, and achieves isolation and remediation to the insecure endpoint.

Key words: network access control, Trusted Network Connect(TNC), 802.1X technology, isolation
