Secure and Resilient A Strategic Framework for Critical National Infrastructure In Scotland

Listen

DEFINING CRITICAL NATIONAL INFRASTRUCTURE ( CNI)

When approaching infrastructure security and resilience work, it is important to have clarity of terminology. This section sets out what is meant by the terms 'national infrastructure' and 'critical national infrastructure' ( CNI) and describes in more detail the different national infrastructure 'sectors'.

National Infrastructure

The national infrastructure includes those facilities, systems, sites and networks necessary for the functioning of the country and the delivery of the essential services upon which daily life in the UK depends. Essential services are the fundamental services that underpin daily life and ensure the country continues to function socially and economically. They include: The supply of Energy, Food, Water, Transportation Services and Communications services, Emergency Services, Health Care, Financial services and Government Services. There are nine national infrastructure sectors which deliver essential services. The UK's infrastructure protection effort is organised into these nine sector streams. Activity may also be driven forward on cross-cutting themes such as 'space' wherein there may be infrastructure which supports the delivery of essential services across a number of sectors, or 'personnel security' which will be important to improving security across all of the sectors, but these are not recognised as national infrastructure sectors in their own right.

Critical National Infrastructure

Not everything within a national infrastructure sector is 'critical'. Within the sectors there are certain 'critical' elements of infrastructure, the loss or compromise of which would have a major detrimental impact on the availability or integrity of essential services, leading to severe economic or social consequences or to loss of life. These 'critical' assets make up the nation's Critical National Infrastructure ( CNI)10 and are referred to individually as 'infrastructure assets'. Infrastructure assets may be physical (e.g. sites, installations, pieces of equipment) or logical (e.g. information networks, systems).
