摘要
A method for detecting and combating an attack in an industrial control system includes sending a command stream from a protection network of an industrial control system to at least one zone, the command stream comprising at least one command; concatenating the at least one command into at least one sequential command package comprising units or work; passing the at least one sequential command package to a crypto hash generator; generating at least one of unit of work hash codes or sequence hash codes; comparing the generated hash codes against a database of existing valid unit of work hash codes and sequence hash codes; and if a command stream fault is detected, generating an alert and accessing a database comprising emergency procedures.
