CloudFormation stacks should be tagged
Description
Flags AWS CloudFormation stacks that have no user-defined tags. Stack tags propagate to provisioned resources and are the primary way to associate the stack with its owning team, environment, and cost centre; untagged stacks are operationally opaque.
Remediation
Apply at least one user-defined tag to every CloudFormation stack.
Steps
- Open the CloudFormation console and select the stack.
- Choose Update, Use current template, then Next.
- On the Configure stack options page, add tags with non-aws: prefixed keys.
- Continue through Review and submit the update.
