Method for identifying industrial control protocol dangerous communication data based on Ethernet

The invention provides a method for identifying industrial control protocol dangerous communication data based on Ethernet, which is a method for identifying the danger of the industrial control protocol communication data by using an operation mechanism described by the technical scheme in an industrial control network environment, wherein the dangerous data refer to data transmitted by one end of the two communication ends or data of which one part exceeds a normal use range of an industrial control field or an equipment capability range. Communication of dangerous data usually causes safetyaccidents of an industrial control site. By identifying the dangerous data, safety accidents can be predicted and avoided in advance. The technical problem to be solved by the invention is to providea method for identifying dangerous communication data of an Ethernet-based industrial control protocol in order to overcome the defects in the prior art, and mainly solve the problem of how to reasonably and efficiently ident
