Industrial control network topological graph generation method based on active and passive detection

Abstract

The invention discloses an industrial control network topological graph generation method based on active and passive detection, and the method comprises the steps: S1, capturing network flow data in a passive detection mode, carrying out analysis and formatting of traffic data, and storing traffic data in a database; S2, providing an IP in the traffic data for active detection; S3, performing active detection, firstly performing survival scanning, and recording a current survival IP and port; S4, scanning the currently survived IP and port through an industrial control protocol script, performing route tracking, analyzing and formatting a scanning result and route information, and storing the scanning result and the route information in a database; S5, extracting data from the database according to the filtering condition of the user to draw a topological graph and the like; The network topological graph of the detailed route can be generated for the network environment, the fault node can be found through the topological graph, the network problem can be rapidly and accurately solved, and a path can be provided for better managing and optimizing the network.

Problems solved by technology

[0004] Existing technologies for generating topology diagrams of industrial control networks basically present end-to-end links, without marking the specific routing paths of end-to-end connections. In a huge network system environment, network segment devices are diverse. , in the absence of detailed routing information, it takes a lot of time and energy to troubleshoot which network segment the fault occurs, which is always half the effort
