The Invisible Airborne Perimeter: The Complete Enterprise Wireless Security Programme — Evil Twin Defence, Zero Trust Architecture, NIS2 Compliance, and Board Governance

Your firewall is on. Your endpoint protection is current. Your wireless network is wide open. Most organisations secure their buildings, their servers, and their endpoints — then leave the airspace completely undefended. An attacker with a laptop and a wireless adapter, sitting in a car park, a coffee shop, or a hotel lobby, can impersonate your corporate network, harvest credentials from your employees' devices, and be gone before your SIEM logs a single alert. No malware. No perimeter breach. No trace. This is the invisible airborne perimeter. And this book is the complete field manual for defending it. What this book covers: How wireless attacks work — evil twins, rogue access points, deauthentication floods, SSID spoofing, and credential harvesting — explained at the level of detail a security architect needs The complete S.I.G.N.A.L. framework: See, Identify, Govern, Neutralise, Authenticate, Log — six pillars for building a wireless security programme that runs itself The Airborne Zero-Trust Model (AZT-7): a seven-phase assessment and improvement cycle that replaces point-in-time audits with continuous hardening The Invisible Airborne Perimeter Model (IAP-8): an eight-layer architecture framework that maps every control from physical signal containment to board governance Sector-specific guidance for healthcare, retail, financial services, OT/ICS, data centres, and remote working environments Regulatory alignment across NIS2, PCI DSS v4.0, ISO/IEC 27001:2022, the UK Cyber Security and Resilience Bill, NIST CSF 2.0, and GDPR 12 operational playbooks: step-by-step response protocols for evil twin incidents, rogue AP discovery, nation-state-level wireless threats, IoT compromise, executive travel, and more Board governance language: how to present wireless risk, secure investment, and respond to the five most common board objections Who this book is for: Written for CISOs, security managers, IT architects, compliance officers, and governance professionals who need to build and defend a wireless security programme — and for the board-level executives who need to understand why it matters. Every chapter includes board-ready one-pagers, learning objectives, and regulatory anchors so the book works as a reference across the entire organisation. Why this edition: The Seventh Edition incorporates the 2024–2026 threat landscape: Salt Typhoon and carrier-scale wireless targeting by nation-state actors, the UK Cyber Security and Resilience Bill, NIS2 implementation across EU member states, Wi-Fi 7 security implications, and post-quantum cryptography planning for wireless infrastructure. Every chapter has been updated. Every learning objective is chapter-specific. Every regulatory anchor maps to the frameworks your auditors are using right now. The airspace above your organisation is transmitting right now. The question is whether you are listening.
