Least Privilege Principle

Updated Mar 11, 2022 ·

The "Least Privilege" principle in Kubernetes, like in other security contexts, focuses on giving only the minimum required access for tasks or roles.

  • Limit access to nodes
  • Use RBAC for access control
  • Isolate resources with Kubernetes namespaces
  • Remove unused packages and services
  • Restrict network access
  • Disable unnecessary kernel modules
  • Close open ports
  • Implement pod security policies
  • Prevent resource exhaustion and abuse
  • Enable audit logging
  • Perform regular security reviews

Following the least privilege principle helps reduce unauthorized access, privilege escalation, and security risks in Kubernetes environments.
