Roads, waterways, railroads, airports, power grids, and digital networks power modern economies and build connections between countries. These infrastructure components, however, can be vulnerable weak points in national defense, which if infiltrated or destroyed by malicious actors could disrupt or crash economies and threaten stability. The digital interconnectivity of these assets makes them only more vulnerable to cyberattacks. By focusing on fortifying the defenses of these vital assets, governments can ensure that this infrastructure remains functioning in emergencies and safe from manipulation or attack.
