Course overview
Critical national infrastructure (CNI) operators must protect services whose disruption can affect public safety, economic activity, government functions and essential supply chains. Energy, water, transport, healthcare, telecommunications, financial services and digital infrastructure face combined physical, cyber, insider, environmental and supply-chain threats. Security managers need a defensible basis for deciding which assets and dependencies matter most, selecting proportionate controls, coordinating partners and sustaining services during disruption.
This course examines protection of critical infrastructure as a security management discipline. Participants learn to identify critical functions, map dependencies, assess threats and vulnerabilities, set risk treatment priorities and specify physical, personnel, information and operational technology security measures. The course connects security risk management with business continuity, emergency response, crisis communications and recovery. It uses ISO 31000, ISO 22301, IEC 62443 and the NIST Cybersecurity Framework to structure decisions, evidence and assurance.
Teaching combines short instructor briefings with sector-based cases, facilitated group analysis, incident simulations and structured application planning. Cases reflect realistic issues such as substation intrusion, ransomware affecting hospital systems, water treatment disruption, transport control-room failure and supplier compromise. Participants leave with a completed Critical Infrastructure Protection Plan, including an asset criticality model, dependency map, risk register, control improvement roadmap and incident coordination checklist. The five-day format provides approximately 32.5 contact hours, delivered in the classroom or live online.
The course suits security, resilience, facilities, risk, continuity and operational leaders responsible for essential services or major supporting suppliers. It is particularly relevant where security decisions require coordination between technical teams, public authorities, emergency services, regulators and senior management.
