A vulnerability scanning and verification system for power information systems

Some of the power information system vulnerability scanning and verification system in the process of putting into use, there is a time-consuming defects, in order to design a new power information system vulnerability scanning and verification system. Hardware component: The FLASH chip is chosen as the tool for loading and guiding the main program in the system, expanding the addressing space range on the basis of the original chip capacity. Software part: Identifying security hazards in electric power information system logs, timely process alert information with homologous features, adopt the way of extracting the expected value of anomalous variables, update the maximum value of the lower bound of the initial distribution likelihood function, construct an alert mapping space using a Gaussian mixture clustering model, and optimize the system vulnerability scanning and verification mode with the help of a leakage scanning tool with integrated features. Test results: The time consumption of the power information system vulnerability scanning and verification system in this paper is 5.048min, 8.204min, 8.441min and 8.325min respectively compared to the other two power information system vulnerability scanning and verification systems, indicating that the power information system vulnerability scanning and verification system designed in this paper is more advantageous in terms of time consumption.
