Abstract
Systems and methods for performing access control in an industrial control system are described. A first component of an industrial control system may be connected to a second component of the industrial control system. A digital certificate may be generated for the first component that includes both authentication information and authorization information associated with the first component. The first component may transmit the digital certificate to the second component, and the second component may extract the authorization information from the digital certificate. The second component may identify a set of access rights based on the authorization information extracted and authorize the first component to access the second component based on the set of access rights identified.
