Information Sharing & Analysis

The Department of Homeland Security takes the lead in evaluating vulnerabilities and coordinating with other federal, state, local and private entities to ensure the most effective response. Much of this task involves assessing critical infrastructure, the physical and virtual assets, systems, and networks so vital that their incapacitation or destruction would have a debilitating effect on security, national economic security, public health or safety.

Central to this task is collecting, protecting, evaluating and disseminating information to the American public, to state and local governments and to the private sector.
