Which of the following is the BEST approach for data owners to use when defining access privileges for users?

Implementing an IDM tool is an *enabling technology* for managing access, not an approach for *defining* the privileges themselves.

Adopting vendor-recommended settings might not align with an organization's specific security policies or least privilege requirements.

While a risk assessment of access privileges is important for continuous review, it's a verification step, not the primary method for initial definition of privileges for new users or roles.

Defining access privileges based on user roles (Role-Based Access Control or RBAC) is the best approach because it ensures that users only receive the access necessary to perform their job functions, adhering to the principle of least privilege. This method allows for scalable and consistent privilege management, as access can be granted or revoked simply by assigning or unassigning roles.
