  • Use minimal base images
  • Scan images with tools like Trivy
  • Avoid running containers as root
  • Use Docker Bench for security checks

13. What is Kubernetes Role-Based Access Control (RBAC)?

Answer:
DevSecOps Interview Questions RBAC in Kubernetes controls access to resources by assigning roles to users. It’s critical to restrict what users or services can do in a cluster.

14. How do you implement network policies in Kubernetes?

Answer:
Kubernetes network policies control traffic between pods. Using tools like Calico, you can restrict communications to enforce zero-trust networking.

These DevSecOps Interview Questions around containers are vital for cloud-native roles.
