Secure access control method and device for wireless network

Abstract

The invention provides a secure access control method for a wireless network, which comprises the following steps of: confirming the type of a wireless access terminal according to an MAC (Media Access Control) address of the wireless access terminal; confirming the access permission of the wireless access terminal by utilizing a preset firewall policy according to the type of the confirmed wireless access terminal; and allowing the wireless access terminal to access a network with access permission by utilizing the confirmed access permission. The secure access control method for a wireless network can ensure that the client ends carry out access by the wireless network are trusty and can be used for establishing more flexible access permission according to a role of the client end, thereby meeting the legal access requirements of various roles in different environments and filtering and blocking an illegal unauthorized access request.

Description

technical field [0001] The present invention relates to the field of wireless networks, and more specifically, to a wireless network security control method and device. Background technique [0002] With the progress of society and the development of technology, people increasingly use access terminals to access the Internet or an enterprise internal network in a wireless manner to obtain information. In this case, the confidential information on the internal network of the enterprise is likely to be illegally accessed by unauthorized users, causing the confidential information to spread out, thus causing great economic losses to the enterprise. Therefore, in the internal network of the enterprise, wireless access control needs to be adopted. By installing the wireless access client software on the wireless access terminal and using the wireless access account to centrally manage the wireless access terminal, thereby restricting unauthorized users Illegal access to the inte...

AI Technical Summary

Problems solved by technology

If the client software is installed on the access terminal, the cost of the whole set of products usually exceeds RMB 200,000

[0005] Secondly, the wireless access terminals used in the enterprise usually have multiple requirements and often change, and the existing wireless admission control solutions are difficult to balance security and usability, so they cannot Roles define more flexible access rights

[0006] In addition, existing wireless admission control solutions usually require a dedicated hardware platform to support, which also leads to a very high cost of the wireless admission control solution
