Pros and cons of MAC Pros High level of data protection An administrator defines access to objects, and users can't alter that access. Fortunately, there are diverse systems that can handle just about any access-related security task. Traditional identity and access management (IAM) implementation methods cant provide enough flexibility, responsiveness, and efficiency. (A cynic might point to the market saturation for RBAC solutions and the resulting need for a 'newer' and 'better' access control solution, but that's another discussion.). Privacy and Security compliance in Cloud Access Control.
