ABSTRACT
This chapter discusses the various concepts and definitions of private security, and outlines the various areas of private security involvement in international terrorism, homegrown terrorism, and homeland security in general. It identifies the various laws, regulations, and executive orders that enable private security to carry out its aim and purpose, and valuates how specialized homeland security laws impact how security services are provided. The chapter recalls the training and academic programs in homeland security sponsored by the Department of Homeland Security (DHS) as well as various colleges and universities, describing the interplay between private security and homeland security in the twenty-first century. It explains how private sector security firms and personnel are central and integral in the defense of the nation and summarizes how DHS formally encourages the interplay and cooperation between private sector justice entities and public law enforcement.
