Procurement Ticket AWS S3 Read-Only Roles are a common but sensitive requirement. They give authorized users the ability to list and download objects from S3 buckets without write, delete, or modify permissions. This minimizes risk while still enabling access to necessary data.
The workflow is straightforward if you know the steps. First, verify the procurement ticket has approval from the correct compliance and budget owners. Attach this ticket ID to all related changes in your infrastructure as code (IaC) repository. This ensures traceability and aligns with internal audit requirements.
Second, create an AWS IAM policy scoped for S3 read-only access. Use the s3:GetObject and s3:ListBucket actions, and specify the exact bucket ARN. Avoid wildcards if the bucket list is known; over-scoping is a common failure point in security reviews.
Third, bind the policy to a dedicated IAM role. This role should have no other permissions and a tight trust policy. Limit who can assume it. Add role tags that reference the procurement ticket number for automated inventory and review.
