Mastering eBPF for Linux Observability and Security

A Hands-On Guide for Beginners, DevOps, SREs, and Security Engineers to Build High-Performance eBPF Programs for Tracing, Monitoring, and Firewalls
Unlock the full power of eBPF (Extended Berkeley Packet Filter) and take control of your Linux system's observability, tracing, and runtime security-all without modifying the kernel. Whether you're a DevOps engineer, SRE, beginner system programmer, or a cybersecurity professional, this book delivers the real-world eBPF skills you need to build high-performance tools for network monitoring, system tracing, intrusion detection, and firewall enforcement.
Written in 2025 to reflect the most up-to-date trends, kernel features, and development tools, this practical guide walks you through working eBPF programs-from writing your first tracepoint hook to deploying advanced XDP-based packet filters and Grafana-powered dashboards. You'll learn how to write efficient, safe, and portable eBPF code using both BCC and libbpf, while understanding CO-RE, perf, bpftool, BPF maps, verifier errors, and more.
This isn't a theoretical overview. It's a deeply practical, beginner-friendly book with complete and executable code for custom syscall tracers, TCP connection monitors, file integrity checkers, and runtime firewall logic-all built from the ground up. Whether you're optimizing performance or securing cloud-native infrastructure, this book ensures you understand why and how each piece works.
What makes this book different?
✔ Complete, well-explained, production-grade code examples
✔ Up-to-date coverage of modern eBPF tools, XDP, CO-RE, and bpftool
✔ Designed to accelerate learning for both newcomers and working engineers
✔ Written with clarity, precision, and purpose-every line adds value
