Summary
The NCSC has published a new fictional worked example demonstrating how organisations can apply the Secure Connectivity Principles for Operational Technology (OT). The example explores how a regional water utility might approach the challenge of standardising digital connectivity across its OT environment while maintaining safety, reliability and cyber The aim of the example is not to prescribe a single architecture or implementation. Instead, it demonstrates how organisations can use the NCSC’s Secure connectivity principles as a target state, while making risk‑informed decisions that reflect their own operational context, regulatory obligations and threat landscape. The example highlights how architectural choices, governance processes and operational practices all play a role in achieving resilient OT connectivity. In practice, organisations must balance security, safety, reliability and operational requirements, particularly where legacy infrastructure is involved.
