The door to your cluster should never be left ajar.

Kubernetes access is the most critical part of infrastructure access. It decides who can run workloads, read secrets, or change configurations. Strong controls mean predictable operations and fewer security surprises. Weak controls mean risk spreads fast.

To manage infrastructure access, you must understand how Kubernetes handles authentication and authorization. Access starts at the API server. Every request must be authenticated — often through service accounts, client certificates, or identity providers tied to OIDC. Once a user or service is known, Kubernetes checks RBAC rules. These roles and bindings map actions to resources. The smallest viable permission set is the safest.

Centralized infrastructure access controls help keep Kubernetes security consistent with the rest of your systems. If you run multiple clusters, syncing RBAC and policies by hand is error-prone. Use automation. Integrate Kubernetes access into your company’s identity provider. Apply the same MFA and session rules across clusters and other infrastructure.

Granular Kubernetes access matters for compliance. Audit logs must show who did what, when, and on which resource. Without unified access management, audit data is scattered and incomplete. With strong infrastructure access integration, every cluster event ties back to a trusted identity.

Infrastructure access for Kubernetes is more than a one-time setup. Rotate credentials. Expire tokens quickly. Monitor live permissions and remove idle accounts. Build a repeatable process so onboarding and offboarding are clean and controlled.
