Abstract

The invention provides an industrial control security protection method and device. The method comprises the following steps: acquiring a to-be-identified message which is sent by a to-be-identified host and at least carries a host identifier; determining whether the to-be-identified host is a trusted host according to the host identifier and a trusted host list; when the to-be-identified host is not the trusted host, analyzing the to-be-identified message and determining to-be-identified operation according to an analysis result; if the to-be-identified operation is any preset key operation, intercepting the to-be-identified message; when the to-be-identified host is the trusted host, if the trust value of the to-be-identified host is greater than or equal to a trust value threshold value, sending the to-be-identified message to the target industrial control equipment; and if the trust value of the to-be-identified host is smaller than the trust value threshold, determining to send the to-be-identified message to the target industrial control equipment or intercept the to-be-identified message according to the control authority. When security protection is carried out, the to-be-identified host, the trust value of the to-be-identified host and the operation corresponding to the to-be-identified message are detected, the range of detection objects is enriched, and the security of the industrial control equipment is improved.

Description

technical field [0001] The invention relates to the technical field of network security protection, in particular to an industrial control security protection method and device. Background technique [0002] In the "Public Safety Industry Standards of the People's Republic of China", there are specific safety protection requirements for industrial control equipment. [0003] The current security protection method for industrial control equipment is to use conventional firewalls (or security protection products) to identify and block operation instructions for accessing and controlling industrial control equipment. However, conventional firewalls only detect and block data packets based on IP or MAC, and the detection objects are limited to transport layer quintuples. The range of detection objects is relatively limited, resulting in poor security of industrial control equipment. Contents of the invention [0004] In view of this, the embodiments of the present invention p...
