Embodiment 1

[0035] figure 1 Schematic diagram of the overall framework of the security analysis model for user operation and maintenance operations. On the basis of the theoretical basis and the scene of equipment operation and maintenance operations, a security analysis model for user operation and maintenance operation instructions is constructed. An operation and maintenance operation instruction security analysis method of the present invention includes Follow the steps below:

[0036] Step 1, read the historical operation instruction data, and perform character vectorization processing on the character set of the historical operation instruction data;

[0037] 1) Read the historical data from the specified database, respectively SSH (Secure Shell abbreviation, formulated by the Network Working Group of IETF, SSH is a security protocol based on the application layer and transport layer.) Remote Operation instruction set (133142 groups of instruction data) and Local local operation in...

Embodiment 2

[0057] In step three, the dimensionality reduction method is t-distribution domain embedding algorithm (t-SNE). Compared with the principal component analysis (PCA) method, the two dimensionality reduction methods have their own advantages and disadvantages. However, for the current For the actual data in the scene, the two methods can compare the output data respectively.

[0058] Other technical characteristics are identical with embodiment 1.

Embodiment 3

[0060] In Step 4, the clustering method can also choose K-medoid algorithm, CURE, Chameleon and BIRCH algorithms, etc.

[0061] Other technical characteristics are identical with embodiment 1.

Abstract

The invention discloses an operation and maintenance operation instruction security analysis method and system and a storage medium, and the method comprises the following steps: 1) reading historicaloperation instruction data, and carrying out character vectorization of a character set of the historical operation instruction data; 2) taking the vectorized operation instruction data as input, establishing a neural network model, and forming a mesh relation graph of the operation instruction data; 3) performing data dimension reduction processing on the operation instruction character data inthe mesh relation graph; 4) performing data clustering processing after the data dimension reduction processing is finished; and 5) performing definition and arrangement of black and white grey listson the operation and maintenance instruction data set clustered in the step 4) according to an actual service scene to form output data, and writing all black and white grey list output data into a specified database. According to the method, the problems of difficulty in manually labeling categories, excessively complicated labeling and the like in the operation and maintenance operation instruction security analysis process are solved, and the automation degree of operation and maintenance operation instruction security analysis is improved.

Description

technical field [0001] The invention relates to a safety analysis method for operation and maintenance operation instructions, which belongs to the technical field of safety analysis of operation instructions during the operation and maintenance operation of electric power systems. Background technique [0002] In recent years, with the "smart manufacturing" proposed by the new national strategic transformation of Made in China 2025, the intelligence and intelligent processing of data information has become the current mainstream research direction. In the actual operation process of the power system of the State Grid Corporation of China, and under the background that its marketing strategy is more systematic, scientific and operable. Enterprise operations have strengthened the research on big data in terms of e-commerce and actual operation information collection. The big data research on user behaviors of major online platforms and e-commerce is particularly significant. ...
