The first layer of homeland defense is the National Security Strategy (NSS). The NSS provides a framework for how the United States pursues security in an increasingly uncertain world. It sets out the nation’s strategic priorities and guides how the government works to achieve those objectives. Some of its core goals include protecting U.S. citizens and interests, promoting global peace and stability, and strengthening international partnerships (U.S Department of State, 2021).

The second layer is known as an Integrated Homeland Defense System (IHDS). This system integrates all federal, state, local and tribal entities that are responsible for protecting the homeland from threats or disasters. IHDS coordinates resources across agencies to ensure an effective response when threats arise; it also serves as a tool to identify areas where improvements can be made in order to prevent disaster or attack (Department of Homeland Security, 2021).
