Under-documented Kubernetes Security Tips

Securing a Kubernetes cluster is a complex task that goes beyond just patching CVEs and following security guides. In addition to technical measures, organizations need to establish and enforce policies, implement segregation of duties, provide security training, and periodically review everything.

Access to the Kubernetes API is sensitive and using wildcards in roles can lead to unintended consequences. It's important to remember that Kubernetes is essentially remote-code-execution-as-a-service and to take authentication seriously, have an intrusion detection system, and consider running multiple clusters to reduce the blast radius.

Ultimately, organizations need to take Kubernetes security seriously and not rely solely on flashy security tools.
