What does an identity management system ensure?

An identity management system is designed to manage user identities and their access to resources securely and efficiently. The primary goal of such a system is to ensure that the right individuals receive access to the right resources based on their roles, responsibilities, and needs. This involves verifying user identities, assigning appropriate access rights, and monitoring usage to prevent unauthorized access.

In this context, the correct answer emphasizes ensuring access is appropriately allocated, which reflects the foundational principle of identity management—granting permission based on established policies and justifications. This not only enhances security by limiting access to sensitive information and systems but also ensures compliance with regulations and organizational standards.

The other choices do not accurately describe the purpose of an identity management system. They either imply unrestricted access or lack the necessary checks and balances to maintain security and governance over user privileges.
