Best Practices for Managing Access to Cloud Storage Buckets

A.

The best answer for this scenario would be option D, which is to set up Uniform bucket-level access on the Cloud Storage bucket and manage access for users using IAM.

Uniform bucket-level access (UBLA) is a Cloud Storage feature that provides a uniform access control model across all the objects in a bucket. This means that you can manage access to all the objects in your bucket with a single set of IAM policies, rather than having to manage access to each object individually.

With UBLA, you can define IAM policies that specify who has access to your bucket and what actions they can perform on the objects in the bucket. You can grant users permissions to create, read, update, or delete objects in the bucket, or to perform other actions such as listing the objects in the bucket or changing the bucket's metadata.

Additionally, UBLA allows you to enforce fine-grained access control over your bucket by requiring that users authenticate with a Google Cloud identity before accessing the bucket or its objects. This means that the uploader of an object will not automatically have full control over the object unless they have been explicitly granted those permissions through an IAM policy.

Finally, UBLA works seamlessly with Cloud Audit Logs, which provide detailed logs of all the actions taken on your bucket and its objects. This allows you to monitor and audit access to your bucket in real-time, so you can quickly identify and respond to any security threats or policy violations.

In summary, by setting up Uniform bucket-level access on your Cloud Storage bucket and managing access for users using IAM, you can provide a uniform and secure access control model for all the objects in your bucket, while also leveraging the power of Cloud Audit Logs to monitor and manage access to your bucket.
