Modern-day industrial and critical infrastructure organizations rely heavily on the operational technology (OT) environment to produce their goods and services. Beyond traditional IT operations that utilize servers, routers, PCs and switches, these organizations also rely on OT, such as programmable logic controllers (PLCs), distributed control systems (DCSs) and human machine interfaces (HMIs) to run their physical plants and factories. While OT devices have been in commercial use since the late 1960s, a complete transformation has occurred, changing the way we operate, interact with and secure the OT environment.
As noted earlier, the lineage and approach of the legacy IT and OT teams could not be greater opposites. And this polarity goes far beyond far product life cycle timelines.
