It is intended to be the primary resource for any introductory course in homeland security studies or an invaluable desk reference for the security practitioner. This text reference is divided into two parts. The first section focuses on the foundations of homeland security. The "what", "why", and "how" of homeland security are all examined in great detail. The second section concentrates on the functions of homeland security. Administration, mission, adversaries, and preventative measures are all included in the second half of this resource. In its entirety, the concept of homeland security is explicitly investigated. Presenting critical materials in this format allows the reader to gain a broad understanding of the general concepts involved in homeland security, while focusing on department or agency-specific models. In addition, the theories, practices, and terminology examined throughout this reference, while specific to United States homeland security efforts, are rapidly becoming industry and world standards.
