Critical infrastructure

Critical infrastructure, or critical national infrastructure (CNI) in the UK, describes infrastructure considered essential by governments for the functioning of a society and economy and deserving of special protection for national security. Critical infrastructure has traditionally been viewed as under the scope of government due to its strategic importance, yet there is an observable trend towards its privatization, raising discussions about how the private sector can contribute to these essential services. It is important to distinct between critical maritime infrastructure (CMI) and critical terrestrial infrastructure (CTI) because CMI reflects the maritime dimension of critical infrastructure while CRI reflects the land-based dimension.
