allowing a third party application to write to your aws bucket

Question

I'm not sure I know the solution to a minor issue I'm having. I want to grant access to a third-party developer (who is creating the web application) so they can upload files to my staging bucket.

What is the proper procedure for doing this? I mustn't be divulging my aws secrets, right?

If someone could send me on the right path for this, that would be amazing.

To grant access to a third-party developer to upload files to your staging bucket in AWS without divulging your AWS secrets, you can follow these steps:

1. Create an IAM User: In the AWS Identity and Access Management (IAM) console, create a new IAM user specifically for the third-party developer. This user will have limited access only to the necessary resources.
2. Assign IAM Permissions: Attach an appropriate IAM policy to the IAM user you created. The policy should grant the necessary permissions to upload files to the staging bucket, while restricting access to other resources and services. It's essential to ensure that the policy allows only the minimum required permissions for the user to perform their tasks.
3. Generate Access Keys: In the IAM console, generate access keys (Access Key ID and Secret Access Key) for the IAM user. These access keys will be used by the developer to authenticate their API requests to the AWS services.
4. Share Access Keys Securely: Safely transmit the access keys to the third-party developer. You can use secure methods like encrypted messaging or password-protected files to share the access keys. Make sure to emphasize the importance of keeping the access keys confidential and not sharing them with unauthorized individuals.
5. Configure AWS SDK or API Integration: The third-party developer will need to configure the AWS Software Development Kit (SDK) or API integration within their web application using the access keys provided. This will enable them to authenticate their requests to the staging bucket and perform file uploads securely.
6. Implement Bucket Policies (Optional): For an extra layer of security, you can implement bucket policies on the staging bucket. Bucket policies allow you to define granular permissions and access control rules for specific actions on the bucket, further restricting access if necessary.

By following these steps, you can grant the third-party developer access to upload files to your staging bucket without exposing your AWS secrets. This approach ensures secure collaboration while maintaining control over your AWS resources.
