What are Critical Infrastructure and Key Resources that terrorists target?

Critical Infrastructure and Key Resources (CIKR) refer to the essential systems and assets that are vital for the functioning of a society and economy, including transportation, energy, water supply, and communication networks. Terrorists often target these systems to cause widespread disruption, instill fear, and undermine public confidence. By attacking CIKR, they aim to achieve political, ideological, or social objectives through the resulting chaos and vulnerability. Protecting these assets is crucial for national security and public safety.
