What is a correct access control measure for a user managing certifications?

Assigning the Governance Admin role is a correct access control measure for a user managing certifications because this role is specifically designed to provide the necessary permissions and authority for overseeing governance-related tasks. Governance Admin roles typically encompass the ability to manage and execute certification campaigns, as well as access to sensitive information necessary for compliance and auditing purposes.

This role ensures that the individual has a comprehensive understanding of both the technical and strategic aspects of identity governance, allowing them to enforce policies effectively. Moreover, it aligns with best practices in identity and access management by ensuring that only qualified users have elevated permissions, particularly in areas that influence security and compliance.

In contrast, assigning a 'Viewer' role does not provide sufficient access for a user tasked with managing certifications, as it typically limits the user to seeing information without the capability to make necessary changes or manage campaigns. Granting permissions merely to view and edit campaigns may also lack the broader context needed for governance tasks and could lead to confusion around roles and responsibilities. Lastly, removing all roles before assignment is counterproductive, as it would strip the user of any relevant access, making them unable to perform their responsibilities effectively. Hence, the Governance Admin role is the most appropriate choice for someone managing certifications.
