Every CI/CD pipeline is a supply chain, and every step between source code and production is an attack surface. This guide applies the SLSA framework to harden build pipelines with provenance generation, hermetic builds, and verifiable attestations so your team can prove what ran in production and how it got there.

Most production clusters still run with over-privileged service accounts. Here is a repeatable approach to auditing RBAC, designing scoped roles, and automating enforcement so your permissions stop drifting.

Every GKE cluster that accesses GCP APIs faces the same question: how does a pod prove its identity without embedding a long-lived service account key? Workload Identity replaces static keys with federated IAM, giving pods short-lived, automatically rotated credentials scoped to a specific namespace and service account.

A production Kubernetes outage is not the time to start writing runbooks. Platform teams need pre-built detection signals, triage commands, forensic collection procedures, and communication templates ready before the first alert fires.

Kubernetes Network Policies are the built-in firewall for pod-to-pod communication. This guide covers default-deny rules, namespace isolation, policy testing, and a practical checklist for enforcing zero-trust networking in production clusters.
