What characterizes Attribute-based access control (ABAC)?

Attribute-based access control (ABAC) is characterized by the fact that access rights are determined based on various attributes of the user, the resource, and the environment, and governed by specific policies. This model allows for a more granular level of control compared to traditional access control methods.

In ABAC, attributes can include user characteristics such as job title, department, or clearance level, as well as environmental attributes such as the time of access or the location from which a request is made. The access decision is made through policies that evaluate these attributes against predefined rules, allowing organizations to tailor access controls to their specific needs and contexts.

The use of policies in ABAC enables dynamic access control decisions that can change based on the combination of attributes. This flexibility makes ABAC particularly suitable for complex environments where users may need access based on various situational factors rather than a one-size-fits-all role-based approach.

Other options suggest limitations or alternative methods of assigning access rights. For instance, restricting access rights solely based on user roles does not reflect the adaptability of ABAC, which incorporates multiple attributes. Claims that access decisions are made only by administrators or on a first-come, first-served basis do not align with the principles of ABAC, which
