CISA and the UK National Cyber Security Centre (NCSC-UK), in collaboration with federal and international partners, have released Secure Connectivity Principles for Operational Technology (OT) guidance to help asset owners address increasing business and regulatory pressures for connectivity into operational technology (OT) networks.

This guidance outlines eight principles to use as a framework to design, secure, and manage connectivity into OT environments. These principles are particularly critical for operators of essential services.
