Build a Lightning Fast Firewall with Java and eBPF

Learn how to build a high-performance firewall by combining eBPF and Java in this conference talk from Copenhagen Developers Festival. Explore the revolutionary potential of eBPF in cloud native environments for enhancing kernel-level performance, security, and observability, while leveraging Java's modern capabilities through Project Panama. Discover practical techniques for implementing kernel-level packet manipulation, deploying eBPF programs using the hello-ebpf library, and creating efficient firewall rules. Master the integration of low-level kernel operations with high-level Java programming to achieve optimal performance in real-time packet processing and network security implementations. Gain hands-on experience in building a simple yet powerful firewall system that demonstrates the seamless interaction between eBPF's kernel-space capabilities and Java's advanced programming features.
