Secure IT/OT Convergence: Defending OT Operations with Zero Trust
The convergence of IT and OT networks has increased the attack surface for hackers targeting critical industrial operations. This brief from Zentera Systems explores securing IT/OT convergence through zero trust security segmentation and controls.
Key points:
- Hackers are increasingly targeting OT networks, with a 2,204% increase in reconnaissance activity from 2020 to 2021
- The traditional Purdue Model for OT segmentation is difficult to implement, leading to flat and mixed IT/OT environments
- Traditional network segmentation using firewalls and VPNs creates challenges
Zentera's CoIP Platform offers a software-defined solution to apply zero trust security policies across IT, OT, and cloud environments without expensive network changes. The platform provides a "zero trust DMZ" for protected assets, integrated zero trust network access (ZTNA), and visibility and control.
