Wireless network security control method, device and wireless router

Abstract

A wireless network security control method, a wireless network security control device and a wireless router are provided. The wireless network security control method comprises the steps of receiving a radio-frequency signal sent by a connecting end, detecting the waveform of the radio-frequency signal, and judging that the connecting end is an attack source when the waveform of the radio-frequency signal is matched with a preset flooding attack waveform. Through the wireless network security control method, the wireless network security control device and the wireless router, denial-of-service attack against a wireless local area network can be distinguished effectively.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a wireless network security control method, device and wireless router. Background technique [0002] Among many computer networking technologies, wireless local area network plays an irreplaceable role in many application occasions due to its advantages of no wiring, low cost, and simple maintenance. As wireless LAN usage increases, it will extend wired LANs and perhaps replace them in some cases. It can be predicted that in the era of ubiquitous information in the future, wireless local area network will rely on its incomparable flexibility, mobility and strong scalability to obtain wider applications, so that people can really enjoy simple, convenient and fast connection . [0003] With the wide application of WLAN, its security issues are becoming more and more important. Currently, denial of service attacks, such as ARP attacks and ICMP attacks, are common attac...

AI Technical Summary

Problems solved by technology

For example, an ARP attack is an ARP spoofing by an attacker by forging IP addresses and MAC addresses, and continuously sending out response requests, thereby generating a large amount of ARP traffic in the network and seriously consuming network resources and device resources

For another example, the ICMP command can be used to check whether the network is unobstructed. By continuously sending ICMP packets, the wireless LAN is bombarded, causing the network to be slow or even the equipment to be paralyzed.

[0004] Existing wireless routers can realize wireless signal sending and receiving functions and data forwarding functions, but cannot effectively prevent the above-mentioned denial of service attacks, thus causing hidden dangers to the network security of the LAN
