Abstract

The invention discloses a user security access control method as well as a device and a system thereof, applied to a user network access process. The user security access control method comprises the following steps: a client of a user is authenticated by an authentication server and requests a DHCP server for obtaining an IP address; the DHCP server receives the request sent by the client for obtaining an IP address; the DHCP server obtains an IP address level corresponding to the client from the authentication server according to the request; the DHCP server assigns an IP address of a corresponding network to the client according to the obtained IP address level and sends the assigned IP address to the client. and the IP address level of the client is decided by a security level which is obtained by the client after security detection. The invention is applied to improve the security of the user access network while simplifying the control flows of the user access network and improving the reliability of the access control process.

Description

technical field [0001] The present invention relates to network access technology in the communication field, in particular to a user security access control method and its device and system. Background technique [0002] With the rapid development of broadband networks and the continuous increase in the number of users, hidden dangers of network security have become an increasingly prominent problem. While disseminating information, the network may also disseminate viruses, which is particularly obvious in enterprise networks or campus networks. If there is a problematic terminal in the network, and if there are no necessary protective measures in the network, the consequences will be unpredictable. [0003] How to effectively control the spread of network viruses is a common concern in the industry at present. Every network administrator hopes to have a way to limit the access of terminals with potential safety hazards (such as terminals infected with viruses or susceptib...
