Kubernetes RBAC Security Hardening
Default Kubernetes clusters are wide open. We harden RBAC with least-privilege roles, pod security standards, admission controllers, and audit policies so every user and service has exactly the permissions they need — nothing more.
Need this done for your project?
We implement, you ship. Async, documented, done in days.
Role Design
We design ClusterRoles and Roles based on your team structure: developers get read access and deployment rights to their namespaces, CI/CD pipelines get scoped service accounts, and cluster-admin access gets restricted to ops leads.
Service Account Hardening
Default service accounts get disabled. Each workload gets a dedicated service account with minimal RBAC bindings. Token auto-mounting is disabled unless explicitly needed. Pod security standards enforce baseline or restricted profiles.
Audit & Compliance
Kubernetes audit logging captures who did what and when. We set up OPA Gatekeeper or Kyverno policies to enforce security constraints at admission time — preventing misconfigurations before they're applied.
