NCSC Issues New Principles for Secure Connectivity in OT Environments

The UK National Cyber Security Centre (NCSC), together with international partner organisations, has published a set of secure connectivity principles to help organisations design, review and secure connections both within and to operational technology (OT) systems.
As OT environments become increasingly interconnected, poorly secured connections can leave critical infrastructure vulnerable to cyber threats. The guidance promotes a principles-based approach that emphasises understanding the purpose and risks of each connection, minimising exposure, and building security into connectivity decisions from the start.
It also stresses the importance of managing supply chain risks and establishing clear objectives to limit the potential impact of any compromise, thereby supporting improved resilience and protection for OT systems.
