A mobile cellular network application layer data flow fuzzy testing method, electronic equipment and storage medium

Abstract

The embodiment of the present invention provides a mobile cellular network application layer data flow fuzzy testing system and method, the system includes: a device under test, a base station radio signal modulation and demodulation device, a control terminal and an accessed target device; a middleman is deployed on the control terminal The proxy server is a transparent proxy; the traffic forwarding module of the control terminal forwards the data flow of the device under test sent by the radio wave signal modem device of the base station to the corresponding port of the intermediary proxy server according to the set firewall traffic forwarding strategy; the fuzziness of the intermediary proxy server The test module is used for fuzzing and forwarding data traffic. The mobile cellular network application layer data traffic fuzzy testing system and method provided by the embodiments of the present invention, by setting the firewall traffic forwarding policy to forward the traffic data and by setting the transparent proxy, can realize that the device under test does not need to access WIFI or set up an Internet proxy server. Fuzz testing of the device under test can be realized.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a mobile cellular network application layer data flow fuzzy testing system and method. Background technique [0002] At present, the network security performance of IoT devices has been paid more and more attention, and its traffic security is an extremely important part of network security performance. The mobile cellular network connection of IoT devices conforms to the traditional OSI seven-layer model from the network layer to the application layer. Therefore, the mainstream traditional computer network traffic analysis software is also suitable for the application layer traffic analysis of IoT devices. These software include: Wireshark, TCPDump , Fiddler, Burp Suite Pro, etc. [0003] ·Wireshark [0004] Wireshark is the most extensive and best-used network packet analysis software in the world, with powerful functions and easy operation. Its predecessor is E...

AI Technical Summary

Problems solved by technology

[0020] However, with the large-scale promotion of 4G / 5G, more and more IoT devices can only use mobile cellular networks and cannot connect to designated WIFI

Therefore, the method of deploying a hotspot network cannot meet the needs of IoT device fuzz testing

In addition, because the method of configuring the LAN proxy needs to set up an Internet proxy server on the IoT device, but currently most custom-developed IoT devices cannot set the Internet proxy server, therefore, the method of configuring the LAN proxy cannot meet the fuzzing test of the IoT device. needs
