Critical Infrastructure and Key Resources (CIKR)

Critical Infrastructure and Key Resources (CIKR) are essential assets and systems that support the nation's safety, economy, and well-being. This includes vital sectors such as energy (power plants), transportation (roads, airports), water supply, healthcare, finance, and communications. These resources are crucial for everyday functions and national security. Protecting CIKR ensures that disruptions—whether from natural disasters, cyberattacks, or other threats—are minimized, helping communities stay resilient and maintain essential services during crises.
