Running Amazon EKS Benchmark Assessments

Problem

The CIS Amazon Elastic Kubernetes Service (EKS) Benchmark requires certain Linux environment variables to be in place before CIS-CAT Pro Assessor can conduct a scan successfully. If these are not set correctly, Recommendations in the report may contain unexpected Fail or Unknown results.

Solution

Ensure that all other prerequisites (such as kubectl and the AWS CLI) are in place and properly configured as outlined in the CIS-CAT Pro Assessor Configuration Guide:
https://ciscat-assessor.docs.cisecurity.org/en/latest/Configuration%20Guide/#amazon-elastic-kubernetes-service-eks-assessment

Then set the following environment variables on the system hosting Assessor:

• export NODE_NAME=(node name)

  • Example: export NODE_NAME=ip-172-31-125-147.ec2.internal

• export CLUSTER_NAME=(cluster name)

  • Example: export CLUSTER_NAME=eks-cluster-test-a1

• export REGION_CODE=(region code)

  • Example: export REGION_CODE=us-east-1

When invoking Assessor, add the -E (or --preserve-env) parameter to sudo to retain the set values.
The below example will use the “Level 1 - Cluster / Control Plane” Profile:
