The offshore team had full network access. You needed them to read data, not change it. One wrong permission on AWS S3, and the line between safety and disaster vanished.
Offshore Developer Access Compliance is not theory—it is about hard controls. When developers are outside your primary jurisdiction, you must enforce strict boundaries. AWS S3 Read-Only Roles are the simplest and most effective layer to prevent write or delete actions.
Start with IAM.
Create a role with permissions limited to s3:GetObject and s3:ListBucket. Avoid wildcards when scoping resources. Use explicit bucket names to keep offshore access precise. Attach the role only to the offshore developer accounts or federated logins you control.
Enable bucket policies that reinforce read-only rules. Even if IAM misconfigures, the bucket policy should hard-stop unwanted writes. Use AWS condition keys for source IP to ensure offshore traffic originates from approved networks. This meets compliance for data sovereignty and privacy regulations.
