Network access control method for comprehensive safety management of inner network

The invention relates to a network access control method for the comprehensive safety management of an inner network. The network access control method is characterized in that the safety control of a network access terminal is realized by the linkage among a comprehensive inner network safety management system, a switch and a Radius server. The network access control method is realized by the following steps: firstly, pointing an 802.1 X authentication server to the Radius server and dividing into three vlans of a working area, an access area and a repairing area by a switch with the 802.1X access authentication function; and then, configuring the access control strategies of the vlans on the Radius server and the linkage configuration with the comprehensive inner network safety management. The invention can manage and control the terminal safety and saves network resources by freeing detection in a continuous scanning mode.
