Threat processing system based on smart grid information security detection

Abstract

The invention requests for protecting a threat processing system based on smart grid information security detection, mainly relating to the following three parts: smart grid framework abstract design,SGN-based data flow diagram design and analysis on a data flow diagram. In combination with a bidirectional communication characteristic result of an intelligent electric meter, the data flow diagramabout a smart grid is obtained; and finally, the data flow diagram is analyzed, so that a threat on data storage and data flow identifiers is obtained. The method is mainly combined with 5 entity objects, 6 data storages, 9 processing programs and 39 data flows in the data flow diagram; due to analysis on the flow diagram, potential threats in the smart grid can be analyzed; applications and essential assets associated with prime assets in a power grid system are determined; and furthermore, the essential assets are protected through a layered attribute encryption method, so that the assets are protected.

Description

technical field [0001] The invention belongs to the intersection field of smart grid and information technology security, and in particular relates to a threat processing system based on smart grid information security detection. Background technique [0002] At present, with the development of economy, social progress, improvement of scientific and technological level, and the increasingly prominent global energy and environmental problems, the power grid is an important infrastructure for social and economic development, an important content of energy strategic layout, and an important link in the energy industry chain. Development is facing new opportunities and challenges. In order to solve the persistent and terrible threat of global warming to the environment, the application of smart grid can improve the management efficiency of energy resources and reduce CO 2 emissions play a vital role in mitigating global warming. [0003] However, due to the interactive charact...

AI Technical Summary

Problems solved by technology

[0004] In the existing smart grid information security monitoring, the following models are mainly applied: one is ISO7498-2, which describes functional services and technical mechanisms, and the other is P2DR and PDRR, which explain the important links of information security. Security technology, although P2DR and PDRR put the strategy of security management at the core, but these technologies do not reflect many aspects of information security construction in addition to technology management in each functional link, so they lack three-dimensionality

There is no or less consideration of factors other than technology, and at the same time, there is a lack of linkage in all aspects, so that it cannot provide comprehensive guidance for the construction of the security system of the smart grid.
