To ensure only authorized users can access an organization's Cloud Storage, what is a relevant policy to implement?

1. Domain-restricted sharing

2. Standard public access permissions

3. Permit all service accounts

4. Open buckets for public access to test settings

The correct answer is: Domain-restricted sharing

Implementing domain-restricted sharing is a relevant policy for ensuring that only authorized users can access an organization's Cloud Storage. This approach allows the organization to control who can view or use their data by restricting access to users within a specified domain, typically the organization's domain. This restrictiveness is essential for maintaining security and compliance, as it ensures that only employees or trusted partners who are part of the organization can access sensitive data stored in Cloud Storage. In contrast, using standard public access permissions would allow anyone on the internet to access the data, which poses significant security risks. Similarly, permitting all service accounts to access the storage would not provide the necessary control over who can access the data since service accounts may belong to various applications or projects that could be outside the organization's scope. Lastly, opening buckets for public access as a testing measure can lead to unintended exposure of sensitive data and is not a secure practice for maintaining data confidentiality and integrity. Thus, domain-restricted sharing stands out as the most effective means to protect access to Cloud Storage by ensuring that only authorized users are granted permissions.
