Problems solved by technology

[0009] When an AP launches an attack, because it scans all channels, the AP no longer provides hotspot access services, but instead becomes a dedicated attack device. If there are always illegal hotspots in the environment, and there are user terminals trying to connect to them, our The AP will always be in the attack state, which will bring two problems: one is to reduce the number of AP devices that provide hotspots on site, and the pressure on other AP hotspots will increase. The originally designed network coverage layout will be affected, and the user experience will be poor.
The other is that if the ssid of the illegal AP device is modified, it needs to be re-scanned to attack. This requires on-site construction personnel to operate in real time, and it is not a cure for the symptoms.

Embodiment 1

[0027] A technology for detecting and suppressing illegal APs based on wireless positioning, comprising the following steps:

[0028] Step a, open the illegal AP scanning function, if there is an illegal AP device, then skip to step b, otherwise end;

[0029] Step b, draw a plan in the detected area, where the position of the legal and normal AP equipment is marked;

[0030] Step c, stepping on the detected area to locate the detected area, the stepping on the detected area is to place the mobile device at various positions in the detected area, the mobile device turns on wireless but does not connect to any AP device, and simultaneously turns on The wireless positioning function of the AP device, when the mobile device is in a certain position, marks the position of the mobile device on the plan and coordinate map, and records the rssi information of the signal message received by the AP devices around the mobile device, And report the marked coordinate map and rssi informat...

Embodiment 2

[0038] A total of 13 devices are deployed in the office area for wireless coverage. Depending on the size of the monitored area, the number of AP devices can be appropriately increased or decreased. Multi-AP device deployment, as long as the installation location is appropriate and the interference between APs is small, it will have a very good effect on the coverage of the entire area, wireless transmission quality, and the positioning and eradication of illegal AP devices.

[0039] Step a, open the illegal AP scanning function, if there is an illegal AP device, then skip to step b, otherwise end;

[0040] Step b. Draw a plan in the office area, where the location of the legal and normal AP equipment is marked;

[0041] Step c. Locate the detected area: we turn on the wireless with the mobile phone but do not connect to any signal, walk slowly in the office area, and at the same time turn on the wireless positioning function of the on-site AP device. When the mobile phone is...

Abstract

The invention discloses an illegal AP detection and suppression technology based on wireless positioning. The technology comprises the following steps of Sa, starting an illegal AP scanning function, if an illegal AP device exists, jumping to a step Sb, otherwise, finishing the steps; Sb, drawing a plane graph in a detection region, and marking a position of a legal normal AP device; Sc, carrying out footprinting positioning on the detection region; and Sd, positioning the illegal AP device, finding the illegal AP device and thoroughly dismantling the illegal AP device. According to the technology, a wireless positioning function is increased, the source of an illegal AP hotspot is directly cut off, the problem that the hotspot is fished is solved fundamentally, the onsite network deployment coverage is not influenced, and the security is greatly improved.

Description

technical field [0001] The invention relates to illegal AP detection and restraint technology. Background technique [0002] With the maturity and popularization of WIFI wireless technology, people's demand for using wireless network to surf the Internet in public places has been fully met. High-speed network and relatively low cost make WIFI network the first choice for people to surf the Internet. But in the same place where there is light, there will be darkness, and the WIFI technology that brings convenience to people also brings threats to people. In public areas, criminals set up phishing hotspots with the same name as normal hotspots to induce users to connect, thereby intercepting user data and information for illegal activities. This vulnerability has attracted the attention of many wireless manufacturers, and illegal AP detection technology has emerged as the times require. [0003] At present, the general implementation steps of illegal AP detection and suppres...
