Reflecting the diverse and specialized nature of the security industry, this volume provides an up-to-date treatment of a topic that has become increasingly complex as more vulnerabilities arise. Topics discussed include the history of security and the role of security professionals, terrorism and national strategies for homeland security, crime prevention through environmental design, workplace crime, insider threats and pre-employment screening, and executive and personnel protection. The book also examines the security of physical structures, threats to information security, security law and liabilities, risk management, and the future of security technology.
