Today, threats to the security of an organization can come from a variety of sources — from outside espionage to disgruntled employees and internet risks to utility failure. Reflecting the diverse and specialized nature of the security industry, Security: An Introduction provides an up-to-date treatment of a topic that has become increasingly complex as more vulnerabilities arise.

Philip P. Purpura, recently selected by Security Magazine as one of the Top 25 Most Influential People in the Security Industry, shares his 30-plus years of professional experience in the industry to provide basic theory and real-world methodologies that security practitioners can apply to scenarios they encounter.

Topics discussed in this broad-based text include:

  • The history of security and the role of security professionals
  • Terrorism and national strategies for homeland security
  • Crime prevention through environmental design
  • Violence, theft, and drugs in the workplace
  • Insider threats, pre-employment screening, and executive and personnel protection
  • The security of physical structures
  • Threats to information security, including malware and botnets; and risks to proprietary information and communication
  • Security law and liabilities
  • Investigations, interrogations, and surveillance
  • Risk management, threats from natural disasters, and business continuity/enterprise resilience
  • Critical infrastructures and key national resources
  • The future of security technology

Utilizing real-world examples, each chapter begins with learning objectives and a list of key terms and ends with discussion questions, role-playing exercises, and links to relevant websites. The book offers readers a foundation for understanding and implementing best practices for security to more effectively protect people, assets, and organizations.


For a long time, the security profession has lacked a comprehensive text addressing the fundamentals of protecting people, assets, and organizations. Security: An Introduction by Philip Purpura, CPP, is that book. Purpura has written a work that can be used as a text for the student studying security or in a criminal justice program, as a reference book for security specialists, and as a guide for organizations. He draws on his vast experience as a security professional to provide an exhaustive security curriculum for students, instructors, seasoned security professionals, and administrators alike. … Purpura has provided the security community with a thorough and well-organized text that addresses every aspect of security in a definitive way. This book, likely to become an influential one, could be a useful resource for both students and security practitioners.
