The Principle of Least Privilege is a key concept in information security, emphasizing that team members should only have access to privileges required for their tasks. As organizations using Terraform grow, implementing this principle becomes increasingly important and can be challenging. To address this, Terraform Cloud has introduced Custom Workspace Permissions, allowing organization owners to specify granular permissions for each workspace using a new UI. This feature enables mixing and matching of existing permissions, restricting access to State Versions, and setting customized permissions for teams. It's essential to note that while this feature enhances security, it should be part of a larger defense-in-depth approach and complemented with strong oversight and CI/CD processes.
