Amazon Elastic Kubernetes Service (EKS) is a managed Kubernetes service that makes it easy to run Kubernetes on AWS without needing to install, operate, and maintain your own Kubernetes control 1 plane. Essentially, AWS handles the heavy lifting of managing the core Kubernetes components, allowing you to focus on deploying and securing your applications.
Key Cybersecurity Considerations:
- Managed Control Plane: AWS manages the control plane, including security patches and updates. This reduces your attack surface but also means you have less direct control.
- Worker Nodes: You manage the worker nodes, which are the VMs where your applications run. Securing these nodes is crucial. This includes patching, hardening, and access control.
- IAM Integration: EKS integrates with AWS Identity and Access Management (IAM), enabling granular control over who can access your cluster and resources. Proper IAM configuration is paramount for least privilege.
- Network Security: EKS leverages AWS VPC networking, allowing you to isolate your cluster and control network traffic. Security groups and network ACLs are essential tools.
- Secrets Management: Sensitive data, like passwords and API keys, should be managed securely using AWS Secrets Manager or similar tools.
- Audit Logging: Enabling Kubernetes audit logs and AWS CloudTrail logs provides essential visibility into cluster activity, aiding in threat detection and incident response.
In simpler terms
Think of EKS as a pre-built, secure platform for running your containerized applications. AWS takes care of the critical infrastructure, and you focus on building and securing your applications within that environment. You are still responsible for the security of your nodes, and the applications that run on them.
