What is the recommended method for configuring permissions on a public cloud object storage bucket?

• A. Role-based access control
• B. Access control list authorization
• C. Federation model
• D. Identity management system

Answer: (B)

The most effective method for configuring permissions on a public cloud object storage bucket is role-based access control (RBAC). This approach allows organizations to assign permissions based on roles within the organization, rather than assigning permissions to individual users directly. RBAC streamlines management by enabling users to inherit permissions aligned with their roles, ensuring that access is granted based on job functions and responsibilities. Moreover, it enhances security and governance by adhering to the principle of least privilege, meaning that users can only access resources necessary for their tasks. Access control lists (ACLs) do provide granular permissions for cloud storage and could allow individual management of access; however, they can become unwieldy with larger teams and more complex access structures. This makes RBAC a preferable option for scalability and manageability. The federation model primarily refers to the establishment of identity associations across different systems, and while it is important for single sign-on (SSO) and external identity management, it does not directly address permission configuration within a cloud storage context. An identity management system, though crucial for managing user identity and access across services, does not specifically configure permissions on an object storage service like a bucket. Therefore, the most appropriate and recommended method for configuring permissions on a public cloud object storage bucket is
