The practical engineer's guide to 5G security — authentication, key management, SUCI privacy, SBA, SEPP roaming, network slicing, RAN, core, and cloud-native protection. 35 chapters · 397 hand-drawn diagrams · labs · checklists · interview prep.
From the long-term key on a SIM card to the SEPP guarding the roaming border — every layer of 5G security.
Built by a telecom engineer for telecom engineers — and the SOC teams who defend the network.

“Every security mechanism in 5G exists because somebody, somewhere, successfully attacked an earlier generation.”
A 5G network carries your payments, your hospital's telemetry, your country's power-grid signaling, and two billion private conversations — across an air interface that anyone with a $300 software radio can listen to. That is the problem 3GPP security was built to solve.
Think of mobile security as a door that gained one more lock with every generation — and every lock was added after a break-in. 2G authenticated you to the network but never the network to you. 3G fixed that with mutual AKA. 4G built the key hierarchy. And 5G finally closed identity privacy, user-plane integrity, core trust, and roaming…
Telecom engineer with deep RAN, core, optimization and standards expertise. Author of the CafeTele engineering book series and founder of cafetele.com. This book distills 3GPP security into something you can actually deploy, monitor, and audit.
Instant online access. After payment via Razorpay the full 35-chapter reader unlocks immediately in your browser — like Kindle, with a chapter sidebar — with lifetime access. No subscription, no recurring fees.
Yes. Chapters 1 to 3 are completely free, no signup required. Read them and confirm the depth before you buy.
Yes. It is built on TS 33.501 (verified v18.11.0, Rel-18) and the wider 33-series, with TS 23.501/502 for architecture. Each chapter cites exact spec numbers; Rel-19 content is flagged to verify against the latest version.
Basic telecom/4G familiarity helps, but Part 1 builds the foundations. RAN, core, security and SOC engineers, students, and trainers all get value.
INR 999 if you pay from India, USD 9.99 internationally. Pick your currency on the buy panel. One-time payment.
Yes. Every lab uses free open-source tools — Open5GS, UERANSIM, Wireshark — on an isolated test setup. Chapter 33 has full instructions.
