Revealed: Sophisticated ‘Watering Hole’ Attack – But By Whom? What to do: After installing the Calico CNI, create a GlobalNetworkPolicy to prevent all pods from connection to the kubelet’s port 10250/TCP. Securing your Elastic Kubernetes Service (EKS) cluster’s network traffic and access is crucial for the entire cluster’s security and operation. What to do: EKS provides a couple options for protecting a cluster’s API endpoint. Amazon Elastic Container Service for Kubernetes, Amazon EKS, provides Kubernetes as a managed service on AWS. If you need Windows nodes, you may want to place them on dedicated VPC subnets and use VPC network ACLs to limit traffic to and from the nodes. You can change your ad preferences anytime. KAREN BRUNER | 2019-09-13. Because of the potential for vulnerabilities like that bug and in general for the Kubernetes API server, the endpoint should be protected by limiting network access to the API service only to trusted IP addresses. Understanding the Kubernetes networking framework, and applying network protections to your cluster’s components and workloads provides another piece of the EKS security puzzle. What to do: If only sources inside the cluster’s VPC need to access the service’s endpoint, add the following annotation to the Kubernetes Service manifest to create an internal load balancer: service.beta.kubernetes.io/aws-load-balancer-internal: 0.0.0.0/0. Why: By default, EKS leaves the Kubernetes API endpoint, the management interface to the control plane, fully open to the Internet.

Best practice rules for Amazon Elastic Kubernetes Service (EKS) Ensure that AWS EKS security groups are configured to allow incoming traffic only on TCP port 443. Why: By default, when creating a Kubernetes Service of type LoadBalancer in an EKS cluster, the cluster’s AWS controller creates an Internet-facing ELB with no firewall restrictions other than those of the subnet’s VPC network ACL. In an EKS cluster, by extension, because pods share their node’s EC2 security groups, the pods can make any network connection that the nodes can, unless the user has customized the VPC CNI, as discussed in the Cluster Design section. Different pod attributes, like labels or namespaces, can be used in addition to standard IP CIDR blocks to define the rules. Ensure that EKS control plane logging is enabled for your Amazon EKS clusters. 1. Our goal is to position you to kickstart your Kubernetes journey, as well as reinforce the long-term security, reliability, and efficiency of your systems. kube-bench is a Go application that checks whether Kubernetes is deployed securely by running the checks documented in the CIS Kubernetes Benchmark. AWS Security Group Best Practices. It also changes the way the you secure your environment in significant ways. If you think there are missing best practices or they are not right, consider submitting … EKS supports having both a public and private endpoint enabled for a cluster, so even if you still require the public endpoint, you can still keep your cluster traffic inside the VPC by using a private endpoint. Why: By default, network traffic in a Kubernetes cluster can flow freely between pods and also leave the cluster network altogether. You will learn various security best practices based on CIS Benchmarks for Amazon EKS v1.0.0. EKS Security Best Practices: Running and Securing AWS Kubernetes Containers .

This method provides the best protection but access to the endpoint from outside the VPC, if needed, would require going through a bastion host. This course is completely focused on Amazon EKS Security. Opening all kind of ports inside your Amazon EKS security groups is not a best practice because it will allow attackers to use port scanners and other probing techniques to identify applications and services running on your EKS clusters and exploit their vulnerabilities. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.

If the load balancer needs to be Internet-facing but should not be open to all IP addresses, you can add the field loadBalancerSourceRanges to the Service specification. Follow the below recommendations and best practices to protect your Kubernetes network on EKS. Set up Amazon CloudWatch Container Insights for your cluster. Creating restrictions to allow only necessary service-to-service and cluster egress connections decreases the number of potential targets for malicious or misconfigured pods and limits their ability to exploit the cluster resources. With the launch of an instance in a VPC, users can assign a maximum of five security groups to the specific instance. Why: As mentioned above, by default, all EKS clusters have only an endpoint publicly available on the Internet. We have already seen at least one major security bug around allowing anonymous connections, last year’s Billion Laughs Attack. A multi-tenant SaaS application on EKS provides you with multiple possibilities for compute, network, storage isolations, while keeping the workflow secured. Disable the public endpoint and only use a private endpoint in the cluster’s VPC. What to do: Install Calico and create network policies to limit pod traffic only to what is required. In addition to protecting the API service from Internet traffic, use network policies to block traffic from pods in the cluster to the API endpoint, only allowing workloads which require access. Secure Container Images. Download our 41-page ebook for a deep dive into EKS security, including building secure images and clusters, securing your cluster add-ons, protecting running workloads, and more.
