Which access control mechanism identifies users based on their identity and assigns resource ownership accordingly?

The chosen answer is Identity-based Access Control, which focuses on identifying users based on their specific identities and granting them access to resources according to predefined rules and policies. In this model, access rights are assigned to individual users or groups based on their identity, allowing for a tailored approach to resource management. This mechanism ensures that only authenticated and authorized users can access certain resources, thereby enhancing security.

Identity-based Access Control is pivotal in environments where user responsibilities and access needs can change frequently, as it provides a clear and direct method to manage permissions. In addition to supporting the principle of least privilege, it also allows administrators to efficiently manage and audit user access, ensuring compliance with organizational policies.

Other options have different focuses that do not align specifically with the identification of users and the assignment of resource ownership based on their identity. For example, Implicit Deny is a security principle that states any access not explicitly granted is denied, but it does not address how users are identified or access is assigned. An Access Control Matrix provides a structured way to define access rights for various users across different resources but does not inherently identify users based on their individual identities. Discretionary Access Control allows owners of resources to decide who has access to their resources, which is a different concept that
