Critical Infrastructure Protection is a way to keep important places safe from danger. It is like a strong shield that can stop burglars and other bad people from entering or damaging the places or things that are important to our country. Critical Infrastructure includes places like power plants, airports, financial centers and water systems. To protect these places, special security systems and guards are put in place. They make sure that the places stay safe, so that we can keep the things that are important to us running smoothly.
