This sheet presents a structured security maturity model for OpenShift environments. It outlines basic, intermediate, and advanced stages covering hardening, RBAC, compliance automation, runtime monitoring, and software supply chain protection. Built-in tools such as Advanced Cluster Security and compliance operators support continuous enforcement and reporting aligned with CIS and NIST frameworks. The maturity journey helps organizations move from reactive security to proactive, automated governance. By embedding controls into platform operations, teams strengthen resilience, reduce risk, and maintain compliance across Kubernetes deployments.
