Abstract

The invention discloses a security protection method, device and system for a power information network. The method comprises the steps of: dividing the power information network into at least one network security domain, wherein the network security domains are sub networks having the same security protection demand in the power information network; and deploying network isolation equipment between the network security domains, wherein the network isolation equipment is used for executing at least one of the following functions: network access control, data transmission limitation, security detection, virus blockade, flow cleaning and network recovery. The method, the device and the system solve the technical problem that the existing power information network has security risk in the absence of a perfect network security guarantee architecture.

Description

technical field [0001] The present invention relates to the field of power grids, in particular to a safety protection method, device and system for a power information network. Background technique [0002] With the rapid development of information technology in our country, computers and information networks are playing an increasingly important role in promoting national economic and social development. Strengthening the supervision and management of the security protection of computer information systems in important fields and cracking down on various computer illegal and criminal activities are important guarantees for the smooth development of my country's informatization. [0003] At present, the existing information system of the provincial power company mainly faces two problems: one is the illegal intrusion into the information system of the provincial power company from the outside, the deliberate destruction of the information system, theft, and tampering of inf...
