beginners guide to Kubernetes Security

Kubernetes, known for its orchestration capabilities, requires a security-first approach to ensure data integrity and system resilience. Let’s explore the fundamental principles of Kubernetes security to lay a solid foundation for your cybersecurity journey

Understanding the Fundamentals

Establish a solid foundation by exploring the core tenets of Kubernetes security:

1. Cluster Security

  • Segregation: Segment clusters to restrict access based on roles and responsibilities.
  • Network Policies: Define network policies for secure communication within clusters.
