Emerging Consensus on ICS Security

Whitepaper on Expert Recommendations for OT Security Best Practice

An increasing body of experience OT security, as well as the emerging Industrial Internet of Things (IIoT) are driving a new consensus as to the difference between information technology (IT) and operations technology (OT) security programs. NIST, ANSSI, the ARC, the Gartner Group and others all recognize that preventing mis-operation of industrial control systems (ICS) in order to protect safe and reliable operations is a fundamental priority for industrial sites, while the priority on IT networks is “data protection.”

In this whitepaper we break it down to the following chapters:

  • What is OT Security
  • How OT security is different from IT security
  • Perimeter security – preventing vs. detecting attacks
  • Controlling information flows
  • Industrial Internet of Things (IIoT)


A wide variety of experts, standards and guidance are going on the record regarding firewalled connectivity for OT networks, recommending that Unidirectional Security Gateways and related technology be used instead of firewalls in many industrial contexts. In particular, Unidirectional Gateways are seen as important enablers of IIoT deployments. Unlike firewalls, Unidirectional Gateways can connect industrial networks directly to IT, Internet and cloud systems with 100% hardware-enforced protection from remote cyber threats.
