Whether you're deploying your first reverse proxy or managing high traffic production infrastructure, this book gives you the practical knowledge to use NGINX with confidence. Learn not just what each feature does but why it matters, how to avoid common mistakes and how to build fast, secure, reliable systems that scale.

Learn Python as a network engineer, not as a computer science student. 632 pages, every example built on real device output. Cisco-first, with Juniper and Fortinet.

Adversaries are recording encrypted traffic today to read it once a quantum computer arrives. NIST published the replacements in 2024, and OpenSSL ships them now. This is the migration: measured on one laptop with stock OpenSSL 3.5.5, with every claim labeled verified, reported, or proposed.

Build fast, reliable networked applications with Go by mastering socket programming from the ground up. Through practical examples and production-focused techniques, you will learn how to design scalable servers, implement modern network protocols, secure connections and optimize performance using idiomatic Go and the standard library.

Master Kong API Gateway with a practical guide that takes you from core architecture to advanced AI-powered API management. Learn to build secure, scalable platforms with production-ready examples, explore Kubernetes, decK and Terraform workflows, and discover how Kong AI Gateway enables intelligent LLM routing, semantic caching, guardrails and cost optimization across modern AI applications.

Apache APISIX is redefining what an API gateway can do in the age of AI. This hands-on guide takes you from the fundamentals to production-ready deployments, showing you how to build secure, scalable, and intelligent gateways for APIs, microservices and AI applications. With practical examples, you will gain the skills to confidently deploy, manage and optimize modern API infrastructure.

It's a practical book. We're going to build something real together, a University API, and we're going to grow it chapter by chapter until it looks like a system you'd be proud to deploy. We'll start with a few endpoints, give it databases, make it concurrent, lock it down with authentication, wrap it in containers, and finally split it into cooperating services that talk over the network.

Here's a shorter version:Go beyond DNS lookups and build a high-performance recursive DNS resolver in Zig from the ground up. Through a hands-on implementation, you will master the protocols, algorithms, and systems programming techniques that power one of the internet's most essential services.

Offensive Security with Kali Linux is a practical guide to ethical hacking and penetration testing, taking you from foundational Linux and networking concepts to advanced exploitation techniques. With a strong emphasis on ethical practice and real-world methodology, you'll learn to identify vulnerabilities, assess systems responsibly, and strengthen security using Kali Linux.

Design, build, and operate a Cisco SD-Access campus fabric — greenfield and brownfield — through one realistic, end-to-end project.

Stop memorizing networking concepts—start understanding how real networks work. This book takes you from network architecture and TCP/IP fundamentals to routing, switching, wireless security, common cyber attacks, and defense-in-depth strategies. Perfect for students, IT professionals, and anyone beginning a career in cybersecurity.

Build your own 24/7 internet radio in a single weekend — on a €5 server, understood down to the last line. Ten chapters from bare server to on-air: the tower (Icecast), the robot (Liquidsoap), the door (nginx). Every step tested live, every trap marked. Friday it's a napkin sketch; Sunday night a stranger presses play, and it plays.

Everything you need to pass the 300-215 DFIR exam — all five domains, 18 original diagrams, and 159 practice questions — in one clear, unofficial study guide.
