Securing Soft Targets and Crowded Places Resources

Soft Targets and Crowded Places (ST-CPs), such as sports venues, shopping venues, schools, and transportation systems, are locations that are easily accessible to large numbers of people and that have limited security or protective measures in place making them vulnerable to attack. DHS has been working for many years to address ST-CP security and preparedness, with recent shifts in the threat landscape calling for renewed departmental focus on leveraging and maximizing its ST-CP security authorities, capabilities, and resources in an integrated and coordinated manner. 

The resources provided below represent the Department’s unified effort to provide public and private sector partners with updated and relevant information to enhance their preparedness and security.
