Abstract

The invention discloses a security early warning method and device based on protocol identification in a scheduling data network. The method comprises the following steps: preprocessing data coming from a network traffic entrance; performing protocol identification on the preprocessed data; performing deep analysis and early warning on the data subjected to protocol identification; the method hasthe advantages that data in the whole scheduling data network is monitored and subjected to safety protection, and safety early warning is carried out on malicious invasion and other risk behaviors existing in the scheduling data network.

Description

technical field [0001] The present invention relates to the monitoring of dispatching data network, and more specifically relates to a security early warning method and device based on protocol identification in dispatching data network. Background technique [0002] The industrial control system in the dispatching data network mainly relies on forward and reverse isolation devices and vertical encryption machines for horizontal and vertical access control, but there is a lack of effective monitoring and protection methods in each area. In order to improve the reliability, availability and controllability of the network, it is necessary to analyze the protocol identification characteristics of the network communication protocol, that is, the communication fingerprint of the network protocol, so as to be able to analyze the information flow, behavior mode, information dissemination and content on the network. Take control. Research on the characteristics of network protocol ...
