INTECH NOVEMBER/DECEMBER 2017 15 their networks and operations. ISA's Communications Division and Test & Measurement Division currently have a joint working group focused on IIoT with the associated examination of functional and operational security when IoT devices are deployed into a control system. Although the term "cyber" is overused, it truly applies in the world of IIoT; however, new sen - sor and control capabilities bring en hanced attack surfaces in the world of cyber. The central question—and theme of this article—remains. Is it time for a change in cybersecurity for resilient automation systems? In part 2 of this series, the authors will present a more detailed descrip - tion of topological changes and cyber- physical security implications for ex isting automation systems to up- hold cybersecurity assurance. This will include comparing traditional compo - nents and processes associated with COVER STORY defense-in-depth cybersecurity strat- egies and architectures, such as anti- virus software, firewalls, anti-spyware programs, hierarchical passwords, in- trusion detection, and biometric veri- fication; a review of DarkNet's comple- mentary protective measures, which extend beyond a traditional layered approach—focusing on the intelli - gence and protection of each compo- nent in the operational architecture; and describing how DarkNet intro - duces intrinsic, embedded security features in nearly all elements of the end-to-end grid architecture. There is one thing that we can all agree on. Our collective overarching goal is simple: a resilient automation system architec - ture and operating process. n ABOUT THE AUTHORS Peter Fuhr, PhD (fuhrpl@ornl.gov), a dis- tinguished scientist at Oak Ridge National Laboratory, is the director of grid security and also the technology director for the Unmanned Aerial Systems (UAS) Research Laboratory. In addition, he is a professor of electrical engineering and computer science at the University of Tennessee. Fuhr received a PhD in electrical engineering from the Johns Hopkins University. He is the director of the ISA Test & Measurement Division. Sterling Rooke, PhD (ssr@brixon.io), is the founder of Brixon, a technology company focused on industrial sensors with an eye toward cybersecurity and energy security. On a part-time basis, Rooke serves as the director of training within a Cyber Opera- tions Squadron in the U.S. Air Force. He leads airmen through training exercises to prepare for future conflicts in cyberspace. Sterling received a PhD in civil and envi- ronmental engineering from the Univer- sity of Maryland. He is the incoming direc- tor of the ISA Communication Division. View the online version at www.isa.org/intech/20171201.
