This guide walks you through a ten‑step zero‑trust framework for hardening container security—from supply‑chain image signing and SBOM generation to runtime threat detection, network policies, secret encryption, and continuous monitoring—targeted at production Kubernetes clusters of any scale.
This guide explains how to enhance container image security by installing Cosign, generating key pairs, signing images, and configuring Harbor to trust the signatures, including step‑by‑step commands and parameter details for seamless integration of Cosign into Harbor's registry.
This guide explains how Kubernetes signs container images, how to verify those signatures manually or with sigstore policy‑controller, and how CRI‑O in v1.28 can enforce signature policies natively, including configuration, command‑line usage, and handling of error cases.
This article explains Docker's built‑in security mechanisms—including Linux kernel capabilities, image signing, AppArmor MAC, Seccomp syscall filtering, user namespaces, SELinux, PID limits and additional kernel hardening tools—provides configuration examples, command‑line demonstrations, and guidance on using them safely.
