From Connectivity to Control: Building Vendor‑Resilient OT
Summary
This article discusses the increasing third-party risk in Operational Technology (OT) environments due to integrations with vendors and cloud platforms. It proposes a framework for building secure, resilient, and vendor-independent OT architectures, emphasizing zero-trust principles, network segmentation, and secure remote access to protect critical industrial assets.
IFF Assessment
The article provides strategies and principles for defenders to build more resilient OT systems and mitigate third-party risks.
Defender Context
As organizations increasingly connect operational technology to external systems, understanding and mitigating third-party risk is paramount. Defenders should focus on implementing robust network segmentation, zero-trust architectures, and stringent access controls to maintain visibility and control over critical industrial assets, even when partners are compromised.
