Since World War II, the National Security Agency (NSA) and its predecessors have protected the United States’ most sensitive information. As technological advancements have created a more interconnected world with ever-increasing threats, NSA’s mission has expanded. NSA has embraced new responsibilities and operational authorities to ensure our networks remain secure.
Today, NSA’s cybersecurity mission integrates cryptographic expertise, foreign signals intelligence, vulnerability analysis, defensive operations, and more to prevent and eradicate cyber threats to three key areas.
NSA Cybersecurity protects and defends:
- National Security Systems (NSS): Networks that contain classified information or are otherwise critical to United States military and intelligence activities. It is vital that these networks remain secure to ensure U.S. warfighting capabilities are mission-ready and to protect the nation’s most sensitive information.
- The Department of Defense (DoD): U.S. Military services and combatant commands as well as U.S. government agencies and departments related to national security.
- The Defense Industrial Base (DIB): The ever-growing group of companies that design, develop, operate, and maintain the Department of Defense’s critical systems, platforms, and technologies required to defend the nation. Their products, services, and capabilities are vital to the security of the U.S. and our allies.
In an effort to be more transparent, NSA publishes an annual year in review sharing information regarding cybersecurity efforts that better equipped U.S. defenses against high priority cyber threats. NSA’s efforts to help secure the nation’s most sensitive systems also help your cybersecurity because NSA cascades these solutions through public guidance and engages with key technology providers to help them bolster the security of their products and services.
