Fuzz testing method and system suitable for 376.1 protocol safety defect detection

Abstract

The invention discloses a fuzz testing method and system suitable for 376.1 protocol safety defect detection. The method comprises the following steps: setting bidirectional proxy between a power-using information acquisition terminal and a Peach server, wherein the Peach server generates a testing data packet and sends to the power-using information acquisition terminal through the bidirectionalproxy to perform the testing; monitoring an abnormal situation of the power-using information acquisition terminal; sending the monitored abnormal distortion data packet to the power-using informationacquisition terminal to perform the reproduction, recording the reproducible data packet for the subsequent analysis; the system comprises the Peach server and a bidirectional proxy module, wherein the bidirectional proxy module sends the data packet received from the Peach server to the power-using information acquisition terminal from a fixed port; the Peach server comprises a data generation unit, a monitoring unit and a Publisher unit, and is used for generating the testing data and sending the testing data to the power-using information acquisition terminal through the bidirectional proxy module, and performing the monitoring.

Description

technical field [0001] The present invention relates to the technical field of information security, and more specifically, relates to a fuzzy testing method and system applicable to 376.1 protocol security defect detection. Background technique [0002] The electricity consumption information collection system is a key business system in the electricity consumption infrastructure of residents and enterprises. It is a system that collects, processes and monitors electricity consumption information of power users in real time. Functions such as quality monitoring, power consumption analysis and management, related information release, distributed energy monitoring, and information interaction of intelligent power consumption equipment. The system can realize the collection and analysis of power consumption data of distribution transformers and end users through the operation of the master station on concentrator parameter setting and data collection, and realize power consump...
