AWS eks medium security documentation change

Service: eks · 2026-07-01 · Security-related medium

File: eks/latest/userguide/ack-create-eksctl.md

Summary

Removed documentation about --ack-service-controllers flag optionality and security recommendation to enable only necessary controllers.

Security assessment

Deletion of security best practice advice ('For better performance and security, consider enabling only the controllers you need') reduces guidance for secure configurations. This could lead to over-provisioned permissions if users enable unnecessary controllers.

-The `--ack-service-controllers` flag is optional. If omitted, ACK enables all available controllers. For better performance and security, consider enabling only the controllers you need. You can specify multiple controllers: `--ack-service-controllers s3,rds,dynamodb`
