Converged Security: A Physical Security Manager's Guide to Cybersecurity, Operational Technology, and Enterprise Risk

Physical security is no longer confined to guards, gates, cameras, and access control. The systems protecting today's organizations increasingly depend on networks, identities, cloud services, operational technology, vendors, and enterprise infrastructure. Converged Security is a practical guide for physical security managers navigating that changing environment without trying to become cybersecurity engineers. Drawing on nearly three decades of security experience and graduate research into cyber-physical resilience, George D. Latsos examines how physical security, cybersecurity, IT, operational technology, business continuity, supply-chain security, and enterprise risk increasingly intersect. At the center of the book is Balanced Convergence, a practitioner-oriented approach that preserves specialized expertise while integrating governance, situational awareness, decision-making, and incident response. Readers will learn how to recognize cyber-physical dependencies, govern connected security technology, work effectively with technical partners, manage third-party risk, coordinate converged incidents, assess organizational maturity, and build a practical roadmap toward greater resilience. The book also includes scenarios, assessment tools, governance templates, decision aids, maturity guidance, and a practitioner toolkit designed for real-world application.
