IBM Cloud and Terraform: How to use a REST API

Recently, I looked into how to analyze the access management setup of my IBM Cloud account. I wanted to better understand what kind of access policies exist, what service instances are covered by rules and policies, etc. In the past, I have shared with you how to get insights into IBM Cloud account privileges or how to improve security by identifying inactive identities. This time, I looked across the existing APIs to obtain identity and access management (IAM) and resource data. I retrieved, then analyzed that security data. With these insights, it is possible to improve security for your IBM Cloud account and its resources.
