Wireless attack defense method and wireless attack defense device applied to wireless access point (AP)

Abstract

The embodiments of the invention relate to the technical field of communications, in particular to a wireless attack defense method and a wireless attack defense device applied to a wireless access point (AP); the method and the device are used for effective wireless attack defense in time. The wireless attack defense method comprises the steps of receiving a plurality of messages within a preset period of time; analyzing each message in the plurality of messages, and determining attribute information of each message in the plurality of messages, wherein the attribute information comprises the message types and source addresses of the messages; for each piece of attribute information in all the attribute information corresponding to the plurality of messages, when the number of messages corresponding to the attribute information is larger than a threshold value of the message types corresponding to the attribute information, determining the messages, corresponding to the attribute information, in the plurality of messages as attack messages; deleting the messages, which are determined as the attack messages, by using a driving module of the wireless AP. Therefore, the effective wireless attack defense is realized in time.

Description

technical field [0001] The embodiment of the present invention relates to the communication field, and in particular to a wireless attack defense method and device applied to a wireless access point AP. Background technique [0002] With the development of wireless networks, people's lives are increasingly dependent on the network. In the current wireless network environment, malicious wireless network attacks often occur, and wireless attack defense mechanisms have become the focus of ensuring wireless network security. [0003] The current wireless attack defense mechanism mainly adopts the combination of wireless access point (AP for short) and wireless centralized controller (Wireless Access Point Controller, AC for short). AC is used for centralized management of wireless AP, wireless The AP accesses multiple network devices; after the kernel module determines the attack packet, the wireless AP confirms the MAC address of the attacker, and uploads the Media Access Cont...

AI Technical Summary

Problems solved by technology

[0004] This wireless attack defense method in the prior art has a high delay. Usually, after the wireless attack is detected and before the AC takes measures, the communication network of the wireless AP is already in a paralyzed state, or even hangs up. Wireless attack defense cannot be carried out in time, and the efficiency of wireless attack defense is low
