AWS now allows you to validate and enforce required tags in CloudFormation, Terraform, and Pulumi using Tag Policies. By defining mandatory tags like "Environment," "Owner," and "Application," you can ensure consistent tagging across your infrastructure-as-code projects. This feature helps maintain compliance and governance for your AWS resources.

Identifying ownership of non-human identities (NHIs) created through Infrastructure as Code (IaC) poses significant challenges, particularly when automated processes are involved. A tag-based approach is proposed to help determine the human responsible for IaC-generated identities by linking code commits to the resources created, although this requires careful analysis of various components within the IaC framework.
