Homeland Security is a vital aspect of a nation's efforts to protect its citizens from threats, both domestic and foreign. Established in response to events like the September 11 attacks, the Department of Homeland Security (DHS) coordinates various agencies to ensure safety and security across the country. The DHS focuses on multiple areas, including border security, cybersecurity, and disaster response. By working with local, state, and federal partners, Homeland Security aims to prevent terrorist attacks, manage emergencies, and safeguard critical infrastructure, ensuring a resilient and secure nation.
