Embodiment Construction

[0028] Such as figure 1 As shown, the present invention provides a method for evaluating network security alarms of a power monitoring system based on a probability graph model, comprising the following steps:

[0029] S1. Analyze the original warning of the network security management platform of the power monitoring system;

[0030] Including the merging and screening of the original alarm data of the power monitoring system network security;

[0031] S2, forming a characteristic alarm sequence of the power monitoring system;

[0032] Use the clustering algorithm to classify the source IP address, destination IP address, destination port, transport layer protocol and alarm level of the alarm information, and combine the network security management platform of the power monitoring system and the asset account of the cloud platform to obtain the IP corresponding Device name, and further obtain the alarm sequence of the operating characteristics of the power monitoring system...

Abstract

The invention discloses an electric power monitoring system network security alarm evaluation method based on a probabilistic graph model, which belongs to the technical field of electric power monitoring system network security, and comprises the steps of merging and screening original alarm data, forming an electric power monitoring system feature alarm sequence, extracting a feature vector, making a probability model; and judging a power monitoring system network security alarm threat. According to the method, alarms with high threats can be quickly identified from massive network security alarms of the power monitoring system, and the method has very important significance for next emergency response and quick recovery of a service system.

Description

technical field [0001] The invention relates to the technical field of network security of a power monitoring system, in particular to a method for evaluating network security alarms of a power monitoring system based on a probability graph model. Background technique [0002] With the development of power grid technology, automation systems are used more and more widely in the power production environment, and power monitoring systems play an increasingly important role in actual production. Once a network security incident occurs in the power monitoring system, it may cause immeasurable losses. , the Stuxnet incident that attacked Iran's nuclear facilities, the large-scale power outage incidents in the western part of Ukraine, and the multiple large-scale power outages caused by network security incidents in Venezuela's power system, etc., all remind us that the power monitoring system is facing Serious cybersecurity risk. Therefore, each electric power enterprise gradual...
