5 Crucial Steps to Secure Industrial Networks

Nov 7, 2018

Industrial Control Systems (ICS) are the backbone of the global economy. ICS solutions control the operational technology (OT) networks that run large-scale manufacturing facilities, critical infrastructure sites, and many more of the building blocks of modern society.

The OT networks running manufacturing facilities are highly complex and dynamic organisms. They include a broad range of processes, policies, services, and protocols. They also include many assets from multiple vendors – some of which may date back 20-30 years and run old, proprietary protocols which are not even IP-based.

Because of this diverse ecosystem, the legacy solutions that control large-scale OT networks are challenged to provide visibility into exact network structure – or even discover exactly which assets from which vendors are implemented. This security blind spot leaves OT networks highly-vulnerable to targeted attacks, malware and other cyberthreats. And OT networks are in the crosshairs of both nation-state and private players – as is evidenced by the string of OT-specific attack vectors in recent years (Stuxnet, Black Energy, Industroyer, and more).

Legacy ICS solutions were simply not designed to handle today’s volatile and incredibly complex threatscape. This is why OT network stakeholders are actively seeking solutions to help them identify and assess problems and vulnerabilities in mission-critical OT network assets, while at the same time optimizing connectivity and integration between IT and OT networks. Tighter IT/OT integration not only maximizes efficiency and productivity while enhancing competitiveness – it also markedly improves overall enterprise network security.

To meet the challenges of transitioning to a more secure, more efficient OT network, this whitepaper outlines the five crucial steps you should be taking.
