The Control Tower Model: A New Architecture for Secure OT Modernization
A Control Tower Model architecture proposes centralizing access governance for operational technology (OT) environments through secure bastion hosts and zero-persistence workspaces rather than direct connections to critical assets. The approach uses multifactor authentication (MFA), session isolation, and browser-based access to manage the expanding attack surface created by OT modernization and cloud integration. This framework can also serve as a foundation for deploying artificial intelligence (AI) analytics within the security perimeter while maintaining data sovereignty.
Why it matters: OT teams modernizing systems face growing attack surface from remote access, cloud services, and third-party connectivity; the Control Tower Model offers a centralized governance architecture to enforce least-privilege access, audit user activity, and contain lateral movement without sacrificing operational efficiency.
