What does critical infrastructure refer to?

Critical infrastructure refers to the systems and assets that are essential for the functioning of a society and economy. The correct answer highlights that these systems, if incapacitated or destroyed, would significantly impair the economic security of an organization, community, or nation. This includes vital services such as power grids, transportation systems, water supplies, and communication networks, among others. The focus on the impact of the loss of these systems underscores their importance to maintaining safety, commerce, and overall stability within a society.

The other choices do not accurately capture the comprehensive nature of critical infrastructure. While physical structures may play a role in defense, they represent only a small segment of what critical infrastructure encompasses. Information networks sharing intelligence are also important but are specific to communication rather than a broad systemic view. Programs for economic development, while beneficial, do not refer to the necessary systems that underpin a society’s operation and security.
