The term emphasizes the role of the subject in the access management process, as it is the entity that initiates requests and therefore is subject to access controls and policies enforced by the system.

Understanding the role of the subject is crucial for implementing effective access controls because it informs how permissions and authorizations are assigned and managed. For example, identifying who or what the subjects are helps organizations establish role-based access control (RBAC) systems that align permissions with the needs and privileges of different users or applications.
