The US government agency called the Cybersecurity and Infrastructure Security Agency (CISA) oversees the protection of critical national infrastructure from cyber threats. The mission of this organization is to develop security standards for infrastructure, share information on potential dangers, protect civil liberties when performing surveillance tasks, and coordinate with private companies to better defend against hacks.

Functions of the CISA include:

  1. Protecting the nation’s infrastructure from terrorist attacks.
  2. Increase global cybersecurity by developing voluntary standards and best practices with other countries.
  3. Working with small businesses, nonprofits, and federal/state/local governments to protect critical infrastructure networks.
  4. Supporting significant events in the US through planning, coordination, information sharing, and incident management.
  5. Improve the United States cybersecurity posture by identifying risks and mitigation strategies, both short-term and long-term.
  6. Work to reduce cybersecurity risks associated with the nation’s critical infrastructure at home, including special events that attract large crowds, such as political conventions or concerts.


The Cybersecurity and Infrastructure Security Agency (CISA) is responsible for working with the private sector to develop best practices for protecting critical infrastructure from cyber threats. CISA also provides cybersecurity assistance to major events in the United States, such as political conventions or concerts.
