Ensure IAM Does Not Allow Public Access to Cloud Services
Opis
IBM Cloud features the capability for users with specific access roles to create access policies that allow all users (authenticated and non-authenticated) to access resources in the account. This “all users” access in turn ends up in public (including non- authenticated) access to resources. Determine if this capability is required by your organization and disable if not required. Some customer use cases require that certain files or data are made available for all users to access, both authenticated and non-authenticated. Even if the public access setting is enabled, resources in your account are not publicly accessible unless an administrator level user has explicitly created a policy to create public access for a resource. As a best practice, if this capability is not required by your organization, it must be disabled to prevent unintentional misuse.
