Essential systems and services whose disruption would significantly impact national security and public welfare.
Critical National Infrastructure (CNI) comprises the systems, networks, and assets essential for a functioning society—energy, water, transport, communications, health, finance, and emergency services. CNI disruption would significantly impact national security, economic stability, or public health and safety. CNI organisations face elevated cyber threats from nation-states and sophisticated criminals. UK CNI is regulated under NIS Regulations with requirements for risk management, incident reporting, and security measures.
Why It Matters
The DSC Perspective:
CNI organisations face elevated threats and regulatory requirements. If you're in or supplying to CNI sectors, expect heightened security obligations. CNI security failures can affect entire populations.
