What is the role of a Security Principal in Azure RBAC?

In Azure Role-Based Access Control (RBAC), a Security Principal is fundamentally an object that represents a user, group, service principal, or managed identity that requests access to Azure resources. This means that the Security Principal is the entity that can be granted permissions to perform actions on resources within Azure.

By understanding that the Security Principal symbolizes the individual or group seeking entry to a resource, it is also important to recognize how this fits within the broader Azure RBAC framework. For instance, after identifying who the Security Principal is, Azure policies can dictate what resources they can interact with and what operations they can perform based on assigned roles.

The other choices, while related to Azure RBAC concepts, refer to distinct components. Objects representing resources or defining levels of access pertain to what a Security Principal interacts with, while the object managing access permissions relates more to how those permissions are structured and enforced within Azure’s RBAC model. Hence, the correct understanding of a Security Principal focuses on it being the entity making access requests within this system.
