Securing the Linux Kernel with eBPF

eBPF (extended Berkeley Packet Filter) is revolutionizing Linux kernel security and network observability by enabling dynamic, programmable kernel-level introspection without sacrificing performance or stability. Leveraging eBPF, security teams and system administrators can deploy advanced packet filtering, runtime security enforcement, and detailed telemetry all directly inside the Linux kernel. This modern technology is at the forefront of cloud-native security, microservices observability, and zero-trust network architectures, making it an essential tool for today’s Linux security landscape.

Written by a seasoned Linux kernel developer and security expert, this book dives deep into the practical application of eBPF for securing modern Linux environments. Backed by years of experience working on real-world security projects, the author demystifies complex kernel concepts with clear, actionable guidance. Trusted by professionals and organizations focused on elevating their Linux security posture, this resource is both authoritative and accessible.

This comprehensive guide explores how eBPF empowers you to build next-generation Linux kernel security solutions. From understanding core eBPF principles and writing efficient eBPF programs in C, to deploying tools like Cilium for Kubernetes security, the book covers the entire security stack. You'll gain mastery over real-time packet filtering, network flow analysis, performance profiling, and proactive threat detection—all within the Linux kernel itself.
