This new book gives readers a unique approach to the study of security issues, useful for either those already in the field or before they actually find themselves employed in a specific security-related job. Written in a clear, easy-to-understand style, this book gives readers the opportunity to look at security from various perspectives; it grounds them firmly in the history and fundamentals of the field, as well as prepares them for today's most difficult security challenges. Topics comprehensively covered in this book include: the use of technology in physical security; understanding security in the context of setting; security scenarios; public and private police relations; legal liability; internal resource identification; external community connections; and more. Homeland security means security issues are not just for security practitioners anymore. Everyone should be actively educating themselves about security-related subjects, and become familiar with security needs in various target environments. As such, this book is not only for those in the security field, but for others such as school principals, hospital workers, office managers and business executives, and owners and managers of all types of businesses.
