What is a Magnuson Act security zone designed to do?

A Magnuson Act security zone is designed to safeguard against subversive activities. The Magnuson Act, officially known as the Magnuson-Stevens Fishery Conservation and Management Act, provides the framework for managing marine resources but also incorporates provisions to regulate security zones in certain areas for national security purposes. These zones are established to limit access and prevent unauthorized entry around sensitive locations, which could be at risk of subversive activities or threats to national security.

In contrast, options that suggest preventing fishing activities, regulating vessel speed, or promoting recreational boating do not align with the primary objective of a security zone as outlined in the Magnuson Act. While fishing and boating can be regulated under various provisions, the specific purpose of a Magnuson Act security zone is to maintain safety and security around critical infrastructures and resources.
