That is the starting point for adopting the OpenShift Zero Trust Maturity Model. In modern container platforms, threats are not theoretical. They move fast, exploit misconfigurations, and bypass perimeter defenses. Zero Trust replaces blind faith with continuous verification, forcing every user, service, and workload to prove its identity before gaining access.
The OpenShift Zero Trust Maturity Model offers a framework for evolving security posture step by step. It aligns with Kubernetes best practices while addressing OpenShift-specific needs like service mesh integration, cluster operators, and secure multitenancy. The model moves from basic controls to advanced automation and policy enforcement. Each phase establishes stronger identity assurance, tighter segmentation, and more precise monitoring.
Phase 1: Identify and Isolate
Start by mapping application components, APIs, and data flows. Enforce authentication for all cluster endpoints. Apply namespace-level RBAC to limit resource access. Integrate with an identity provider that supports OIDC.
Phase 2: Enforce Access Policies
Deploy network policies to restrict pod-to-pod communication. Use service mesh mTLS to encrypt traffic between workloads. Harden cluster nodes with SELinux and secure boot. Shift from static secrets to centralized secret management.
