Critical infrastructure
• Critical infrastructure assets include
– Structures and buildings
– Networks
– Computer-based systems
– Organisations

Critical assets
• Not all components of the national infrastructure are critical elements
• Criticality does not just depend on the type of facility but also on the number of people affected or other consequences if the facility is damaged or unavailable and cannot easily be replaced.

Critical infrastructure systems
• Our infrastructure is controlled and managed by a wide range of interacting, computer-based systems
• Businesses and essential services to citizens are completely dependent on our ‘digital infrastructure’
• Therefore, all of the systems involved in critical infrastructure management are critical software-intensive systems
Critical national infrastructure introduction video Slide 16
Summary
• National infrastructure is a set of services such as energy, communications and medical services on which society depends.
• Critical national infrastructure are those assets which are needed to deliver these services whose unavailability has serious social consequences.
• Software-intensive systems are used to manage, organize and control our critical national infrastructure so these are critical systems.
