From Federal News Radio:

The Homeland Security Department will channel its efforts into battling terrorism, cyber threats and natural disasters, according to a quadrennial review the agency released Wednesday. DHS released its first quadrennial review in 2010, where it outlined five basic homeland security missions. In the second review, the agency said it will still adhere to the principles, but the “missions must be refined to reflect the evolving landscape of homeland security threats and hazards.”
