Kubernetes Security Fundamentals for Busy Teams

Cloud Native Security

Start with the Basics

Use namespaces to isolate workloads and apply Role-Based Access Control (RBAC) so that developers and services only get the permissions they need.

Enforce Least Privilege

Run containers as non‑root and restrict capabilities. Admission controllers like Gatekeeper or Kyverno can enforce these policies automatically.

Monitor and Patch

Enable audit logging, aggregate it centrally, and keep your images and nodes patched. Vulnerability scanners should be part of your CI pipeline.

Automate Policy

Define security policies as code and test them like any other component. Automation keeps guardrails consistent across environments.

Conclusion

A secure cluster doesn’t require a massive team. With a few focused practices, your Kubernetes platform can stay resilient while your engineers keep shipping features.
