critical infrastructure
Vital societal foundations
Critical infrastructure refers to the essential systems and assets a society depends on to function—power grids, water treatment, transportation networks, telecommunications, financial systems, hospitals.
The term appears frequently in discussions of national security and cyberwarfare, where attacks on critical infrastructure threaten widespread disruption: Hackers targeted the nation's critical infrastructure.
What counts as critical expands over time; the internet itself is now considered critical infrastructure in most developed nations.
