Reseña del libro "THE PERIMETER HAS CHANGED (en Inglés)"
The Perimeter Has Changed: Building and Leading the 3D Physical Security Enterprise is an executive, leader, and practitioner handbook for those responsible for protecting modern organizations whose missions now depend on interconnected physical, cyber, and low-altitude aerial environments. William Edwards, COL (R), CPP, PSP, PCI, presents 3D Physical Security as a new implementation approach to a legacy enterprise-security problem: organizations often possess capable people, technologies, and specialized security functions, yet still struggle when information, authority, and decision time intersect across organizational boundaries. The book organizes the operating environment into three analytical domains-Ground, Cyber, and Aerial- and connects them through mission-based governance, a Decision Perimeter, a governed Common Operating Picture, and Decision Advantage. The Decision Perimeter helps leaders determine which conditions truly matter to a bounded mission decision, while Decision Advantage focuses on whether an organization can establish sufficient understanding, reach the correct authority, preserve lawful and feasible options, and act while the decision can still affect the outcome. Through documented cases, executive actions, failure modes, original illustrations, and a ten-phase transformation methodology, the handbook guides organizations from operating-environment baseline and governance through Ground, Cyber, and Aerial architecture, Common Operating Picture design, decision performance, enterprise integration, evidence-based maturity, and long-term sustainment. Written for executives, boards, security leaders, technology professionals, facilities and operations teams, aviation and UAS practitioners, emergency managers, risk professionals, and transformation teams, The Perimeter Has Changed provides a practical framework for building a security enterprise centered on mission consequence, lawful authority, evidence, resilient decision-making, and measurable performance.
