There are several government agencies that are responsible for cyber security at various levels of government. Here are a few examples:
-
Federal Bureau of Investigation (FBI): The FBI is a federal law enforcement agency that is responsible for investigating cyber crimes, such as cyber terrorism, cyber espionage, and cyber fraud.
-
Department of Homeland Security (DHS): The DHS is a federal agency that is responsible for protecting the United States from a variety of threats, including cyber threats. The DHS works to prevent, detect, and respond to cyber attacks on government and critical infrastructure systems.
-
National Institute of Standards and Technology (NIST): NIST is a federal agency that develops and promotes standards, guidelines, and best practices for cyber security. NIST works with private industry, academia, and other government agencies to improve the security of information systems.
-
Cybersecurity and Infrastructure Security Agency (CISA): CISA is a federal agency that is responsible for protecting the nation's critical infrastructure from cyber threats. CISA works with other government agencies, industry partners, and international partners to enhance cyber security and resilience.
In addition to these agencies, there are also many state and local agencies that have a role in cyber security. It is important for the government to have a coordinated approach to cyber security in order to effectively protect against threats and ensure the resilience of critical systems and infrastructure.
