The Department of Homeland Security is a part of the Executive Branch of the United States government. Its purpose is to evaluate and neutralize threats to national security. Agencies under the Department of Homeland Security include Secret Service and Coast Guard.
Day 2
Ralph Burton, a private investigator hired by Kate Warner, reported to Homeland Security that Reza Naiyeer was possibly involved with Syed Ali and the Second Wave terrorist cell. They alerted CTU and Tony Almeida investigated his background.
Day 3
David Palmer was advised on how to handle the Cordilla Virus by Joseph O'Laughlin, who was the head of the Department.
Day 4
Homeland Security monitored phone calls after the attack on James Heller and picked up a call between Dina Araz and her son.
Day 5
Homeland Security in Los Angeles
The department plays a pivotal role in Day 5, when Karen Hayes and Miles Papazian from the DHS take over CTU Los Angeles following a Sentox VX nerve gas attack that killed nearly 40% of the staff. Their staffers, including Jim Hill, took over CTU despite the survival of most of CTU's own staff. Many of the people at CTU for the rest of the day were from the DHS, giving Hayes and Papazian more control.
Day 6
Via a bulletin issued by White House Chief of Staff Tom Lennox, Homeland Security was to flag any Government employees with a Muslim background and have their duties restricted. This included CTU Agent Nadia Yassir, who brought her complaint to Bill Buchanan.

Background information and notes
- The United States Department of Homeland Security was created after September 11, 2001 to further counterterrorism goals, as CTU does on 24.
- The fact that there is a DHS on the series would set "24" post-2001, as it appears in both the David Palmer and Charles Logan administrations.
