Cyber security is the practice of protecting internet-connected systems, including hardware, software, and data, from digital attacks and unauthorized access. It encompasses a range of technologies, processes, and controls designed to safeguard against cyber threats and ensure the confidentiality, integrity, and availability of information. Effective cyber security is crucial for organizations and individuals alike, as it helps prevent data breaches, financial losses, and reputational damage.

The Cybersecurity and Infrastructure Security Agency (CISA) is a component of the United States Department of Homeland Security (DHS) responsible for cybersecurity and infrastructure protection across all levels of government, coordinating cybersecurity programs with U.S. states, and improving the government’s cybersecurity protections against private and nation-state hackers.
