Abstract

The embodiment of the invention provides a method, equipment and a system for resisting the wireless network flooding attack. The method for resisting the wireless network flooding attack comprises the following steps of: a first access point (AP) obtains the total target webpage address URL (uniform resource locator) number of access times of a wireless station (STA) in a first period; the ratio of the total number of access times and the period time is recorded; if the ratio is more than a preset threshold value, the first AP refuses STA to access the target URL; an identification comprising STA and a strategy execution request message of target URL is sent to an access controller (AC); therefore the AC sends an access denying message comprising the STA identification and the target URL to at least one second AP; and at least one second AP refuses the STA to access the target URL. According to the embodiment of the invention, the safety and the reliability of the access equipment of the whole network can be improved.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method, device and system for resisting wireless network flooding attacks. Background technique [0002] WLAN (Wireless local area network, wireless local area network) is the product of the combination of computer network and wireless communication technology. Users can access the network anytime and anywhere through WLAN, so as to use network resources conveniently. [0003] In a WLAN, the forwarding of wireless network flood packets will directly affect the performance and security of the wireless network. The detection of flooding attacks in the prior art mainly includes: monitoring and collecting statistics on the traffic of wireless mobile terminals, when the message traffic of wireless mobile terminals exceeds a preset threshold, add wireless mobile terminals to the blacklist, and discard wireless mobile terminals to send message. [0004] In the ...
