Critical infrastructure protection is the framework that designates certain assets — energy grids, water systems, financial networks, communications, elections, hospitals — as essential to national survival and assigns federal lead agencies to assess risk, share threat information, and respond to incidents. Presidential Policy Directive 21 organizes U.S. infrastructure into 16 sectors, each with a Sector Risk Management Agency.
DHS designated election infrastructure as a critical sector on January 6, 2017, putting voter registration databases and election-management systems under the same protective umbrella as power plants. After Colonial Pipeline in 2021, TSA used the framework to issue the first binding pipeline cybersecurity directives.
The framework is mostly voluntary outside a few regulated sectors. Most operators are private companies, and federal protection usually means information sharing, advisories, and incident help rather than mandatory standards — a gap critics argue invites exactly the failures it is meant to prevent.
When the framework weakens, attackers exploit the seams between federal warnings and private operations — and ordinary people lose power, gasoline, water, or trust in their ballots.
People often think critical infrastructure is government-owned. In practice, roughly 85 percent of U.S. critical infrastructure is owned and operated by the private sector.
