How does IdentityNow limit the impact of identity data on a certification campaign?

The correct answer highlights the mechanism IdentityNow employs to ensure that individuals do not certify their own access, which could lead to potential conflicts of interest or security risks. When an identity must certify their own access, the system assigns the certification task to their manager. This ensures an additional layer of oversight, as the manager typically has a broader view of the employee's role, responsibilities, and the access they should possess. By doing so, the certification process remains effective and trustworthy, reinforcing accountability within the organization.

In this context, other options do not appropriately address how IdentityNow mitigates risks associated with identity data during certification campaigns. For instance, restricting access completely to managerless identities would not integrate well with organizational hierarchies, where some identities may naturally fall outside of direct managerial oversight. Similarly, the idea of assigning unapproved identities to system administrators presents a security vulnerability rather than a solution, undermining the integrity of the certification process. Lastly, preventing any changes to manager roles could hinder adaptability and responsiveness to organizational changes, negatively impacting the ability to manage identities effectively. Thus, assigning the certification to the manager emerges as the most logical and secure approach in the certification campaign process.
