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.
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.
