Protecting Critical Infrastructure from Cyber Threats

Published, October 30, 2017

The Nation's critical infrastructure provides essential services that underpin American society and sustain the American way of life. We know critical infrastructure as the power we use in our homes and businesses, the water we drink, the transportation systems that get us from place to place, the first responders and hospitals in our communities, the farms that grow and raise our food, and the stores we shop in. In addition to relying on the Internet to stay in touch with friends and family, the essential services that support our daily lives are also dependent upon the Internet.

We play an important role in helping to secure critical infrastructure, not only by practicing good cyber hygiene, but also by becoming well-informed about whether the companies and organizations we do business with adhere to high cybersecurity standards.

On an individual basis, we can:

  • Read the privacy policy of a company or vendor before purchasing a product or service from them.
  • Beware of requests to update or confirm personal information online. Most organizations do not ask for personal information over email.
  • Make sure websites or smartphone apps that ask for personal information (e.g., to pay a utility bill) use encryption to secure their sites.
By working together, we can protect the critical infrastructure on which we all rely, keeping ourselves, our families, our workplaces, and our communities safer and more secure from cyber threats.
