A Holistic Protection Based on Network Access Control

With the heterogeneous threats of network ongoing, the problems of network security become more and more intractable, besides, the compatibility issues of security protection-equipments are emerging in endlessly. Thus, the unified treat management has been a research hotpot currently. In this paper, based on analyzing the status quo of UTM (unified treat management), as well as the performance detects of related equipments, we present the NAC-UTM, a holistic protection scheme of intranet, which combines UTM with technology of network access control. The emphasis of our research is to illustrate the operating principle of UTM-NAC scheme, and then we verify the superiority of this scheme with a simplified experiment. The test result indicates that our solution could greatly promote performance of UTM equipments.
