RBAC and Access Control

Role-Based Access Control (RBAC) manages permissions in Kubernetes.

Secure storage and management of sensitive data.

Frequently asked questions

What is runtime security?

Runtime security monitors and protects containers while they're running. It detects anomalous behavior, enforces security policies, monitors system calls, detects intrusions, and provides threat detection. Tools like Falco, Aqua, and Twistlock provide runtime security for Kubernetes environments.

How can network policies enhance container security?

Network policies allow you to control pod-to-pod communication, implement service mesh with mTLS for encryption, restrict external access, and use private networks. Applying zero-trust networking principles is crucial for a robust defense.

What does the principle of least privilege entail in Kubernetes?

The principle of least privilege means granting only the minimum permissions necessary for a task. In Kubernetes, this involves using RBAC to limit access, running containers as non-root users, and restricting network access with policies.

How should Kubernetes Secrets be managed securely?

Kubernetes Secrets (base64 encoded, not encrypted) should integrate with external secret managers like HashiCorp Vault or AWS Secrets Manager. Regular rotation and restricted RBAC access are also vital to prevent unauthorized exposure.
