Attackers can hide in your network for months before anyone notices. This practical guide shows you how to uncover hidden threats, develop effective hunting strategies and use the right tools to stay ahead of adversaries. Packed with real-world examples and step-by-step guidance, it helps you turn threat hunting into a proactive part of your security strategy.

Learn to build, send, capture and analyze network packets with Scapy, one of Python’s most versatile networking tools. Through practical examples and runnable code, you’ll explore protocols, traffic analysis, PCAP files, custom packet creation and security testing. Whether you’re troubleshooting networks or sharpening your security skills, this book gives you the tools to get hands-on.

The internet depends on a routing system that was never built with security in mind. This book explores how BGP works, how routing attacks happen and how RPKI helps defend global networks. From protocol fundamentals to real-world deployment, it offers a practical look at the threats, tools and decisions that shape Internet routing security.

You can build software with an AI coding agent. A shop owner saw your app and asked: "Can you make one for me? I will pay." You said yes — and then the quiet worry arrived. What if the scope grows? What if the code breaks? What if the client asks something you cannot answer? This book is the answer to that worry: a professional, repeatable way to deliver AI-built software to paying clients. Not hype about getting rich. Not a prototype tutorial. The real work — finding suitable jobs honestly, scoping them clearly, building in small checked steps, verifying quality and security, handing over cleanly, and supporting the result for years.

What does it really take to build a web application from the ground up, without relying on layers of frameworks to do the heavy lifting? Building Modern Web Applications in C takes you from a handful of sockets to a fully functioning, secure and production-ready web service, revealing the inner workings of HTTP, databases, sessions, TLS and everything in between. Through hands-on examples and the evolution of Taskforge, you’ll learn not just how to make a web server work but how to build one you can trust, deploy and keep running in the real world.

Build a practical gRPC foundation through visual explanations of service contracts, remote calls, streaming, reliability, security, and operations.

Understand DNS through clear visual explanations of name resolution, zones, records, caching, security, and practical operations.

A hands-on guide to mitmproxy 12: trust the CA, filter, modify and replay traffic, write Python addons, choose the right proxy mode, intercept mobile apps past certificate pinning, and automate API security tests. Every output shown is a real run against a lab API.

This book is not just a Python course with a networking flavour or a networking course with a few scripts attached. You already know how routing converges, why VLANs leak, and what a half-open TCP session looks like on the wire. What this book adds is the ability to transform that knowledge into code that runs across hundreds of devices, reports accurately on its findings and never makes changes that cannot be undone.

Ingress-NGINX is retired and about half of all clusters still run it. This is the step-by-step playbook for moving production traffic to Kubernetes Gateway API: a verified annotation-by-annotation map (including every no-equivalent case and its workaround), a decision matrix for nine implementations, inventory scripts, zero-downtime cutover and rollback runbooks, and twelve before/after manifests validated against the real CRD schemas.

A capture that's too big, a complaint that's too vague: this book teaches you to get from there to the packets that explain it. Twenty chapters and 80 exercises on real captures take you from your first capture to TLS decryption, scan detection and your own Lua dissector, with the output of commands run in the lab cited on the page so you can check it yourself.

HAProxy Essentials is a practical guide to building, running and troubleshooting HAProxy in production. From core concepts to advanced architecture, it explains how the pieces fit together and what can go wrong. Based on HAProxy 3.4 LTS, with clear notes on 2.8 and Enterprise-specific features.

Self-hosting from home sounds simple until CGNAT, changing IPv6 prefixes and double NAT get in the way. This book shows you how to build Linux infrastructure that actually works on the real Internet, with practical architectures, working configurations and troubleshooting techniques that help you understand what is really happening to your packets.
