Method for detecting illegal AP (Assembly Program) under centralized WLAN (Wireless Local Area Network) environment

Abstract

The invention discloses a method for detecting an illegal AP (Assembly Program) under a centralized WLAN (Wireless Local Area Network) environment and relates to a wireless intrusion detection technique. An AP device and an illegal AP device are adopted in the method; an AC (Automatic Control) device is arranged; the AC device is a wireless controller used for managing the AP, establishing a WLAN and detecting the illegal AP; the AC device comprises a WLAN establishing module, a binary recording module, an illegal AP identifying module, a collecting module and a wireless scanning module which are interacted in turn; the binary recording module is interacted with the AP device; and the wireless scanning module is respectively interacted with the AP device and the illegal AP device. The method can be easily realized; a physical position of the illegal AP can be accurately positioned; the illegal AP in a space can be effectively found; same frequency interference or adjacent frequency interference between the illegal AP and legal AP is avoided; and the method is suitable for the WLAN under various complex networking environments, is free from being restricted by space and field as well as time and weather and can be implemented under any environment.

Description

technical field [0001] The invention relates to a wireless intrusion detection technology, in particular to a method for detecting an illegal AP (Access Point wireless access point) in a centralized WLAN (Wireless Local Area Networks) environment. The method is simple and easy to be used in various environments, and detects illegal APs (rogue APs) in complex WLAN environments through a dynamic detection method. Background technique [0002] The modern WLAN environment is becoming more and more common and widely used; it enables people to connect to the Internet through WLAN hotspots anytime and anywhere, making people's lives more and more rich, but there are many Illegal intrusion technology, illegal AP is a kind of illegal intrusion technology. [0003] Rogue AP refers to an unauthenticated access point in a wireless network, which can provide an entry point for unauthorized network access. [0004] Although IEEE802.1x has a relatively complete security mechanism, most o...

Problems solved by technology

[0004] Although IEEE802.1x has a relatively complete security mechanism, most of them resist attacks by improving the system's own immunity. It is still powerless against attacks such as illegal APs. Therefore, a means is needed to help network managers actively discover Hidden dangers in the network, active defense and anti-attack against wireless attackers at the first time
