Understanding eBPF for Real-Time Linux Security Monitoring

Technical deep-dive on Extended Berkeley Packet Filter (eBPF) tracing, kprobes, tracepoints, bpftrace, and zero-overhead kernel runtime security monitoring.

Executive Summary & Key Takeaways

Kernel-Level Visibility: eBPF enables non-intrusive tracing of system calls, process executions, network packets, and file I/O directly within kernel space.

Zero Context-Switch Overhead: In-kernel JIT-compiled execution avoids costly user-to-kernel space context switches.
