Maritime Security Operations Program

The Maritime Security Operations program encompasses activities required by executive and policy mandates to detect, deter, prevent, disrupt, and recover from terrorist attacks and other criminal acts in the maritime domain. It includes the execution of antiterrorism, counterterrorism, and security response operations. This program conducts and oversees the operational element of Ports, Waterways, and Coastal Security, which complements the other two elements: maritime security regimes and maritime domain awareness.
