Information leakage monitoring method and system, and electronic device

A system for monitoring key information leakage of an Internet of Things (IoT) terminal based on a traffic proxy, comprising:

• a dynamic domain access unit and one or more proxy services, wherein
• the dynamic domain access unit is configured to receive a proxy request sent by the IoT terminal, wherein the proxy request comprises protocol-related information of the IoT terminal, and the protocol-related information comprises part or all of device model information, service type information and data packet information;
• the dynamic domain access unit is further configured to determine a target protocol corresponding to the IoT terminal according to the protocol-related information of the IoT terminal;
• and
• the dynamic domain access unit is further configured to allocate a target proxy service to the IoT terminal according to the target protocol and a usage state and an online state of one or more proxy services in a full traffic proxy pool, send relevant information of the target proxy service to the IoT terminal, so that the IoT terminal accesses the target proxy service;
• wherein the full traffic proxy pool comprises a plurality of proxy services corresponding to different protocols, and the target proxy service is a proxy service corresponding to the target protocol and having a usage state of being idle and an online state of being online in the plurality of proxy services,
• wherein the proxy service is further configured to, in response to the proxy service serving as the target proxy service, forward traffic of the IoT terminal and perform key information monitoring on the traffic of the IoT terminal;
• wherein the proxy request further comprises device identification information of the IoT terminal,
• the dynamic domain access unit is further configured to generate a uniqueness verification identifier according to the device identification information of the IoT terminal and identification information of the target proxy service;
• the proxy service is further configured to, in response to the proxy service serving as the target proxy service and receiving the traffic sent by the IoT terminal, perform service-bound uniqueness verification according to the device identification information of the IoT terminal the identification information of the target proxy service and the uniqueness verification identifier, and perform key information monitoring on the traffic in response to a successful verification.
