Link topology generation and source tracing for network attacks in power systems

Recent years, network attacks have become an urgent problem to be solved in the power system. When abnormal network traffic occurs and it is determined that a network attack has occurred, necessary countermeasures need to be taken. Due to the fact that network attacks often have issues such as unknown sources, unclear intentions, and difficulty in assessing security levels, it is necessary to reconstruct the network attack scenario. This article studies the generation of link topology for tracing network attacks in the power system. Based on network topology inference algorithms, the transmission path of the attack on the network topology is reconstructed to achieve the reconstruction of network attacks. The process of abnormal traffic communication is intuitively reconstructed, high-risk nodes that may cause network vulnerabilities are analyzed, the source of network attacks is located, and network attack tracing is completed.
