The Invisible Airborne Perimeter by Kai London
Your firewall is on. Your endpoint protection is current. Your wireless network is wide open. An attacker with a laptop in a car park can impersonate your corporate network, harvest credentials, and be gone before your SIEM logs a single alert. This is the invisible airborne perimeter — and this is the complete field manual for defending it.
Available on Amazon in Kindle, paperback and hardcover editions.
What this book covers.
How wireless attacks work
Evil twins, rogue access points, deauthentication floods, SSID spoofing and credential harvesting — at the level of detail a security architect needs.
The S.I.G.N.A.L. framework
See, Identify, Govern, Neutralise, Authenticate, Log — six pillars for a wireless security programme that runs itself.
The Airborne Zero-Trust Model (AZT-7)
A seven-phase assessment cycle that replaces point-in-time audits with continuous hardening.
The IAP-8 architecture
An eight-layer framework mapping every control from physical signal containment to board governance.
Sector-specific guidance
Healthcare, retail, financial services, OT/ICS, data centres and remote-working environments.
12 operational playbooks
Step-by-step response for evil-twin incidents, rogue-AP discovery, nation-state wireless threats, IoT compromise and executive travel.
Updated for the 2024–2026 threat landscape: Salt Typhoon and carrier-scale wireless targeting, the UK Cyber Security and Resilience Bill, NIS2 implementation, Wi-Fi 7 security implications, and post-quantum cryptography planning for wireless infrastructure.
The airspace above your organisation is transmitting right now. The question is whether you are listening.
