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.

Cybersecurity or information technology security (IT security) is the protection of computer systems and networks from information disclosure, theft of or damage to their hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide.

Top cybersecurity challenges include evolving ransomware, AI-powered attacks, advanced social engineering, and securing multi-cloud environments. The increasing use of AI by both attackers and defenders is rapidly shaping the threat landscape, while the expansion of remote work has broadened the attack surface for vulnerabilities in areas like IoT devices and supply chains.

The cybersecurity color wheel categorizes cyber teams by their roles:

• Red Team are ethical hackers,
• Blue Team are defenders,
• Yellow Team are developers who build secure applications.
• Purple Team facilitates collaboration between Red and Blue
• Green Team works with Yellow and Blue to implement secure coding practices
• Orange Team trains Yellow developers
• White Team manages the overall strategy, compliance, and coordination.

The Cybersecurity and Infrastructure Security Agency (CISA)  works with partners to defend against today’s threats and collaborate to build a more secure and resilient infrastructure for the future.

As the National Coordinator for Critical Infrastructure Security and Resilience, CISA works with partners at every level to identify and manage risk to the cyber and physical infrastructure that Americans rely on every hour of every day. CISA works with partners to defend against today’s threats and collaborate to build a more secure and resilient infrastructure for the future. Read CISA’s Fact Sheet to learn more.

The National Institute of Standards and Technology (NIST) was founded in 1901 and is now part of the U.S. Department of Commerce. NIST is one of the nation’s oldest physical science laboratories. Congress established the agency to remove a major challenge to U.S. industrial competitiveness at the time—a second-rate measurement infrastructure that lagged behind the capabilities of the United Kingdom, Germany, and other economic rivals.

From the smart electric power grid and electronic health records to atomic clocks, advanced nanomaterials, and computer chips, innumerable products and services rely in some way on technology, measurement, and standards provided by the National Institute of Standards and Technology.

Today, NIST measurements support the smallest of technologies to the largest and most complex of human-made creations—from nanoscale devices so tiny that tens of thousands can fit on the end of a single human hair up to earthquake-resistant skyscrapers and global communication networks.

The United States Department of Defense (DoD, USDOD or DOD) is an executive branch department of the federal government charged with coordinating and supervising all agencies and functions of the government directly related to national security and the United States Armed Forces.

The DOD is the largest employer in the world, with over 1.4 million active-duty service members (soldiers, Marines, sailors, airmen, and Guardians) as of 2021. More employees include over 826,000 National Guard and reservists from the armed forces, and over 732,000 civilians bringing the total to over 2.8 million employees. Headquartered at the Pentagon in Arlington, Virginia, just outside Washington, D.C., the DoD’s stated mission is to provide “the military forces needed to deter war and ensure our nation’s security”.

The Central Intelligence Agency (CIA ), known informally as the Agency and historically as the Company, is a civilian foreign intelligence service of the federal government of the United States, officially tasked with gathering, processing, and analyzing national security information from around the world, primarily through the use of human intelligence (HUMINT) and conducting covert action through its Directorate of Operations.

As a principal member of the United States Intelligence Community (IC), the CIA reports to the Director of National Intelligence and is primarily focused on providing intelligence for the President and Cabinet of the United States. Following the dissolution of the Office of Strategic Services (OSS) at the end of World War II, President Harry S. Truman created the Central Intelligence Group under the direction of a Director of Central Intelligence by presidential directive on January 22, 1946, and this group was transformed into the Central Intelligence Agency by implementation of the National Security Act of 1947.

The United States Department of Homeland Security (DHS) is the U.S. federal executive department responsible for public security, roughly comparable to the interior or home ministries of other countries.

Its stated missions involve anti-terrorism, border security, immigration and customs, cyber security, and disaster prevention and management.

The National Science Foundation (NSF) is an independent agency of the United States federal government that supports fundamental research and education in all the non-medical fields of science and engineering. Its medical counterpart is the National Institutes of Health. With an annual budget of about $8.3 billion (fiscal year 2020), the

NSF funds approximately 25% of all federally supported basic research conducted by the United States’ colleges and universities. In some fields, such as mathematics, computer science, economics, and the social sciences, the NSF is the major source of federal backing.
