Cybersecurity & Infrastructure Security Agency LogoCybersecurity & Infrastructure Security Agency: CISA is the Nation’s risk advisor, working with partners to defend against today’s threats and collaborating to build more secure and resilient infrastructure for the future. The threats we face—digital and physical, man-made, technological, and natural—are more complex, and the threat actors more diverse, than at any point in our history. CISA is at the heart of mobilizing a collective defense as we lead the Nation’s efforts to understand and manage risk to our critical infrastructure.

Cybersecurity: Cyberspace and its underlying infrastructure are vulnerable to a wide range of risks stemming from both physical and cyber threats and hazards. Sophisticated cyber actors and nation-states exploit vulnerabilities to steal information and money and are developing capabilities to disrupt, destroy, or threaten the delivery of essential services. Cyberspace is particularly difficult to secure due to a number of factors: the ability of malicious actors to operate from anywhere in the world, the linkages between cyberspace and physical systems, and the difficulty of reducing vulnerabilities and consequences in complex cyber networks. Of growing concern is the cyber threat to critical infrastructure, which is increasingly subject to sophisticated cyber intrusions that pose new risks. As information technology becomes increasingly integrated with physical infrastructure operations, there is increased risk for wide scale or high-consequence events that could cause harm or disrupt services upon which our economy and the daily lives of millions of Americans depend. In light of the risk and potential consequences of cyber events, strengthening the security and resilience of cyberspace has become an important homeland security mission.

Infrastructure Security: Critical infrastructure describes the physical and cyber systems and assets that are so vital to the United States that their incapacity or destruction would have a debilitating impact on our physical or economic security or public health or safety. The Nation's critical infrastructure provides the essential services that underpin American society.

Emergency Communications: CISA enhances public safety interoperable communications at all levels of government and conducts extensive, nationwide outreach to support and promote the ability of emergency response providers and relevant government officials to communicate in the event of natural disasters, acts of terrorism, and other hazards.

National Risk Management: Critical infrastructure are those assets, systems, and networks that provide functions necessary for our way of life. From generating electricity to supplying clean water, there are 16 critical infrastructure sectors that are part of a complex, interconnected ecosystem including communications, energy, transportation, emergency services, and water. Any threat to these sectors could have potentially debilitating national security, economic, and public health or safety consequences. As the nation’s risk advisor, CISA's mission is to ensure the security and resiliency of our critical infrastructure.


Federal Emergency Management Agency: Mission: To lead America to prepare for, prevent, respond to and recover from disasters with a vision of "A Nation Prepared." FEMA coordinates the federal government's role in preparing for, preventing, mitigating the effects of, responding to, and recovering from all domestic disasters, whether natural or man-made, including acts of terror.
