What is operational technology (OT) security?

Industrial automation assets, including process management, SCADA and industrial control systems, drive processes across critical infrastructure in healthcare, manufacturing, and energy and utilities sectors. As these systems increasingly connect to broader corporate networks, the convergence of operational technology (OT) with traditional IT introduces a new world of cyber threats and vulnerabilities with serious implications for both business and public safety. OT security requires a holistic view of how these environments integrate and a digitization strategy that promotes standardization, operational resiliency and security of industrial assets.

The Storm Threatening Global Manufacturers

We find it in our homes, our cars, at grocery stores and of course work, but it is also rampant in the plants and factories that make the things we use in our lives. The proliferation of technology on the factory floor, coupled with devices having the capability to be 'online' and the extension of the Internet to nearly every nook and cranny, has created the perfect storm. We can see it coming -- it's on the horizon, we are starting to feel the wind blow and small drops of rain are trickling in. The only question left is, when and where will the storm hit next?
