ISA-95 and the Purdue Model

ISA-95 is a standards framework for integrating enterprise and manufacturing operations, including terminology and information exchanged between business and control functions. The Purdue Model is a reference architecture that groups industrial systems into levels from physical processes to enterprise networks. They are related ways to discuss manufacturing architecture, but they are not interchangeable standards or a substitute for a site-specific security design.
