Yor is an open-source tool from Palo Alto Networks that automatically tags cloud resources within infrastructure as code (IaC) frameworks such as Terraform, Cloudformation, Kubernetes, and Serverless Framework. Yor’s use cases also extend beyond security by making it easier to tag resources to allocate costs from a finance and budgeting perspective. Yor can also be built into the CI/CD lifecycle for improved traceability as infrastructure is modified and created. Having consistent tagging will make it simple to trace any misconfigurations back to the original code owners and editors, reducing the time to patch.
