Cybersecurity and Homeland Security

Cybersecurity in homeland security is the protection of government and private computer networks from hackers, criminals, and hostile governments. It covers defending federal systems, guarding sensitive information, and helping businesses and local governments respond to attacks. The Department of Homeland Security, the Defense Department, the White House, and the intelligence community all take part.

People usually ask who coordinates the country's cyber defense, how the military's role differs from that of civilian agencies, and how sensitive but unclassified information is protected. They also ask how companies that work for the government safeguard data and how these efforts connect to wider national security.
