Which agency is responsible for risk analysis and assessment?

The Cybersecurity and Infrastructure Security Agency (CISA) is the correct answer because it is specifically tasked with protecting the nation's critical infrastructure from physical and cyber threats, which involves comprehensive risk analysis and assessment. CISA conducts various assessments to identify vulnerabilities in infrastructure and helps organizations understand and mitigate risks. The agency also develops guidelines and best practices for risk management and shares these resources with various sectors to enhance overall security.

While other agencies like the Department of Homeland Security (DHS) oversee broad national security issues and the Federal Emergency Management Agency (FEMA) focuses on disaster response and recovery, it is CISA's primary role to analyze and assess cybersecurity risks and threats, making it the most relevant agency in this context. The Department of Commerce engages in areas like economic growth and trade, but it does not specifically focus on risk analysis in the same way that CISA does.
