Detailed Description
The technical solution in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
First, a wireless sharing detection system 10 that may be involved in executing a wireless sharing detection method according to an embodiment of the present application is described, please refer to fig. 1, where fig. 1 is a schematic structural diagram of a wireless sharing detection system according to an embodiment of the present application.
The wireless sharing detection system 10 comprises a wireless access controller 11, a switch 12, a terminal access point 13 and a detection access point 14, wherein the wireless access controller 11 is in communication connection with the terminal access point 13 and the detection access point 14 through the switch 12, and the terminal access point 13 is in communication connection with an access terminal 15.
A wireless Access controller 11, referred to as ac (wireless Access Point controller), is a network device for centralized control of a wireless Access Point (AP), and is generally used for issuing configuration to the AP, modifying related configuration parameters, performing radio frequency intelligent management, performing Access security control, and the like. The terminal access point 13 is a wireless access point to which the terminal is connected, and the detection access point 14 is a wireless access point for detecting whether or not a shared wireless network exists.
Alternatively, the switch 12 in this embodiment may include a core switch 121 and an access switch 122, the main purpose of the core switch 121 is to provide a fast and reliable backbone transport structure through high-speed forwarding communication, and the main purpose of the access switch 122 is to allow end users to connect to the network, so the core switch 121 in this embodiment is also communicatively connected to the internet 17 through the egress gateway 16.
The number of the terminal access points 13 may be one or more, each terminal access point 13 is used for connecting the access terminal 15 through a wireless network, and the access terminal 15 accessed by each terminal access point 13 may be one or more.
Alternatively, the terminal access point 13 in this embodiment may be a routing switching integrated device, a pure access point device, or other access devices with a terminal access function.
It should be understood that the detection access point 14 in this embodiment may be the same type of wireless access point as the terminal access point 13, but the detection access point 14 does not provide access to the access terminal 15, but rather performs data monitoring on the wireless network in the surrounding environment.
For the access terminal 15, there may be a situation that the access terminal 15 of a certain legal access terminal access point 13 shares the wireless network out for other terminals to use through the network sharing tool, and the wireless sharing detection device 10 can complete the detection of wireless sharing through the wireless network system itself without deploying a gateway device with a wireless network sharing detection function.
Referring to fig. 2, fig. 2 is a schematic flow chart of a wireless sharing detection method according to an embodiment of the present application, where the method includes the following specific steps:
the terminal access points 13 are registered to the wireless access controller 11, the management of the terminal access points 13 is carried out through the wireless access controller 11, and the wireless access controller 11 controls one or more terminal access points 13 to release a normally deployed wireless network.
The wireless access controller 11 sends the relevant information of the channel to be monitored to the detection access point 14, and the detection access point 14 monitors the channel to be monitored according to the relevant information of the channel to be monitored.
Optionally, the detecting access point 14 in this embodiment may listen to the channel to be monitored in a polling manner, so as to obtain the first listening data.
Optionally, the first listening data may include one or more types of data capable of indicating identities of the wireless network and the communication device, such as beacon frames, probe requests, probe responses, and terminal data messages.
The detection access point 14 analyzes the wireless network existing in each channel based on the monitoring data, or the detection access point 14 sends the monitoring data to the wireless access controller 11, and the wireless network existing in each channel is analyzed according to the monitoring data through the wireless access controller 11.
Next, the detecting access point 14 determines whether the wireless network is a normally deployed wireless network released by the wireless access controller 11 based on the analyzed name of the wireless network, the wireless network BSSID (Basic Service Set Identity), and the like.
Specifically, when the information such as the name of the wireless network and the wireless network BSSID indicates that the wireless network is not configured by the radio access controller 11, it indicates that the detection access point 14 detects that the wireless network is an abnormally deployed wireless network.
When the detection access point 14 detects that there is an abnormally deployed wireless network, it records the related information (such as the name of the wireless network, the wireless network BSSID, the working channel, etc.) of the abnormally deployed wireless network.
After the polling detection of the channel to be monitored by the detection access point 14 is completed, the detected and recorded related information of the abnormally deployed wireless network is reported to the wireless access controller 11.
Optionally, in this embodiment, the detection access point 14 may directly send related information of the wireless network (for example, a name of the wireless network, a wireless network BSSID, a working channel, and the like) to the wireless access controller 11, and the wireless access controller 11 determines whether the wireless network is a normally deployed wireless network released by the wireless access controller 11 based on the name of the wireless network and the wireless network BSSID without performing abnormal deployment or normal deployment of the wireless network.
After determining that an abnormally deployed wireless network exists, the wireless access controller 11 sends a management message to the terminal access points 13 in the abnormally deployed wireless network area, where the management message includes access point-specific message feature configurations corresponding to each terminal access point 13, so as to notify the terminal access points 13 in the abnormally deployed wireless network area to generate access point detection messages based on the corresponding access point-specific message feature configurations, and send corresponding access point detection messages to the access terminals 15 connected to the terminal access points.
The message lengths and/or message transmission intervals configured for different terminal access points 13 are used as access point specific message characteristics corresponding to the different terminal access points 13, and the access point specific message characteristics of the access point detection messages corresponding to each terminal access point 13 are different.
Alternatively, the terminal access point 13 may send an access point detection message to the respective connected access terminal 15 through a User Datagram Protocol (UDP) communication port in use.
After receiving the access point detection message, the terminal access point 13 will send out the access point detection message through the connected access terminal 15 if it is in the wireless network sharing state, and if the access terminal 15 of the terminal access point 13 has illegal wireless network sharing, the access terminal 15 will send the access point detection message through the abnormally deployed wireless network.
The access point-specific message characteristics may be data having differences in message length, message transmission interval, and the like.
For the message length, the radio access controller 11 needs to locally calculate the actual message length when the shared radio network is not encrypted and when different encryption algorithms are used. Furthermore, the terminal access point 13 needs to record the UDP port being used by the access terminal 15 accessing itself.
Next, the radio access controller 11 issues data configuring a radio network requiring the detection access point 14 to monitor channels and BSSIDs corresponding to the abnormally deployed radio network, and issues a specific message feature of the access point to be detected to the detection access point 14.
For example, when the detection access point 14 detects an abnormally deployed wireless network with BSSID of 1.1.1 and channel of 11, the wireless access controller 11 issues all messages configured to require the detection access point 14 to monitor the channel of 11 and the BSSID of 1.1.1.
By detecting the continuous monitoring of the access point 14, second monitoring data is acquired in the channel to be monitored, the message length and/or the message sending interval of the message in the second monitoring data is analyzed, when the message with the message length and/or the message sending interval identical to the specific message characteristic of the access point exists in the second monitoring data, the message meeting the specific message characteristic of the access point is judged, and the message meeting the specific message characteristic of the access point in the second monitoring data is sent to the wireless access controller 11 as a detection result.
Optionally, in this embodiment, the detection access point 14 may also directly send the second monitoring data to the wireless access controller 11, and the wireless access controller 11 determines whether a packet meeting the access point-specific packet feature exists in the second monitoring data.
After receiving the message satisfying the specific message characteristics of the access point sent by the detection access point 14, the wireless access controller 11 determines that there is a terminal access point 13 of an abnormally deployed wireless network based on the message satisfying the specific message characteristics of the access point, and records a wireless network SSID (Service Set Identifier), a BSSID, a channel, an encryption mode, and the like of the abnormally deployed wireless network.
Optionally, the manner of determining whether the terminal access point 13 of the wireless network is abnormally deployed based on the message meeting the access point specific message feature may be that when the message is not sent by the registered terminal access point 13 in the wireless access controller 11 and has the access point specific message feature, it is determined that the terminal access point 13 corresponding to the message has the abnormally deployed network.
Since the message satisfying the specific message characteristic of the access point is used as the second monitoring data which is the same as the first monitoring data and includes data capable of representing the identities of the wireless network and the communication device, the terminal access point 13 having an abnormally deployed network can be located based on the message.
Thus, the present embodiment completes the positioning of the terminal access point 13 performing the illegal wireless network sharing, and then may also perform the positioning of the access terminal 15 performing the illegal wireless network sharing.
The wireless access controller 11, according to the monitored existence of the terminal access point 13 shared by the wireless network, sends a management message to each access terminal 15 connected to the terminal access point 13, where the management message includes a terminal-specific message feature configuration corresponding to each access terminal 15, so as to notify the terminal access point 13 in the area of the abnormally deployed wireless network to generate a terminal detection message based on the corresponding terminal-specific message feature configuration, and send the corresponding terminal detection message to the respective connected access terminal 15.
The message lengths and/or message transmission intervals configured for different access terminals 15 are used as terminal-specific message characteristics corresponding to the different access terminals 15, and the terminal-specific message characteristics of the message detected by the terminal corresponding to each access terminal 15 are different. It should be understood that, in this embodiment, the step of subsequently positioning the access terminal 15 for performing wireless network sharing by the wireless access controller 11, the terminal access point 13, and the detection access point 14 is similar to the step of determining the terminal access point 13 for performing wireless network sharing, except that the wireless access controller 11 issues configuration to make the access terminal 15 connected to the terminal access point 13 for performing illegal wireless network sharing perform sending of the terminal detection message, and then detects the message with the terminal specific message characteristic through the detection access point 14, and other steps are not described herein again.
It should be understood that, in the present embodiment, the detection and the positioning of the abnormally deployed wireless network are repeated for each terminal access point 13 and the access terminal 15, and the detection of the illegal wireless network sharing can be completed for all the terminal access points 13 and the access terminals 15 controlled by the wireless access controller 11.
Optionally, in this embodiment, the radio access controller 11 may start or execute the above-mentioned wireless sharing detection method according to a manual instruction or according to a cycle, and execute the above-mentioned wireless sharing detection method according to a specified time period, so as to complete detection of illegal wireless network sharing.
In order to cooperate with the wireless sharing detection method, embodiments of the present application provide a wireless sharing detection apparatus for a wireless access controller and a detection access point, respectively.
