Embodiment Construction
[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0045]A power station automation system data network security monitoring method, which uses the Snort detection engine to monitor the power station automation system data network on the existing computer network system of the power system. The protocols embedded in the engine include CDT, IEC-60870-101 and The communication protocol including IEC-61850 uses the frame format of the protocol itself to establish engine matching conditions. The operating platform of the monitoring device used in the present invention adopts Sis550CPU as the processor, selects Vortex6082 of ICOP Company as the integrated main board, the memory configuration is 128MB onboard, and the hard disk selects 32MB DOM electronic disk for use. The device uses a streamlined Linux operating system and uses the Snort intrusion detection system (IDS) to complete the det...

The invention relates to a power station automation system data network security monitoring method. An Snort detecting engine is utilized to realize the monitoring for a power station automation system data network on a traditional electric power system computer network system, an inserted rule of the engine comprises communication rules including CDT, IEC-60870-101 and IEC-61850, and the frame format of the rule is utilized to establish an engine matched condition; the monitoring for network security is realized through the following two modes: a. monitoring the data frame content transmitted on the work, using a rule format transmitted by power station data as a reference, permitting the information satisfying the rule format to continuously circulate, and isolating the information unsatisfying the rule format; b. monitoring the real-time flow of a power station data acquisition network, and if finding abnormal network flows, then indicating that abnormal data is transferred, and giving warning information by a power station automation system data network security monitoring device.
Description
technical field [0001] The invention belongs to the technical field of power electronics, and in particular relates to a data network security monitoring method for a power station automation system. technical background [0002] With the development of computer technology, communication technology and network technology, there are more and more data exchanges between substations, power plants, power grid dispatching centers, users, etc. Modern power systems consider the safety and reliability of basic power facilities. , it is increasingly necessary to strengthen the consideration of information security. The improvement of the automation level of electric power production has led to a large number of event communications such as remote control and monitoring, which poses new severe challenges to the security, reliability, and real-time performance of power control systems and data networks. [0003] The power system computer network system is divided into four safe work a...
