A comprehensive guide detailing how to implement portable Kubernetes NetworkPolicies to enforce zero-trust microsegmentation. Learn to apply default-deny rules, control ingress and egress traffic, and restrict lateral movement between pods and namespaces across various CNI platforms (Calico, Cilium). Ideal for establishing robust security posture and meeting compliance requirements.

A comprehensive guide on implementing advanced security observability using eBPF and Cilium Tetragon. This skill covers real-time tracking of process execution, network connections, and file system access directly in the kernel. Learn how to author TracingPolicy CRDs, utilize kprobe/tracepoint hooks for in-kernel filtering, and enforce runtime security policies (e.g., process killing) on Linux hosts or Kubernetes clusters.

Use eBPF for deep kernel-level observability: trace syscalls, network flows, and application behavior without code changes using Cilium, Tetragon, and bpftrace.
