VisokaNivo 1Ručni pregledgcp

Opis

It is recommended that IAM policy on Cloud Storage bucket does not allows anonymous or public access. Allowing anonymous or public access grants permissions to anyone to access bucket content. Such access might not be desired if you are storing any sensitive data. Hence, ensure that anonymous or public access to a bucket is not allowed.
