If you need to decide who can access a file based on its owner, its sensitivity, and the time of day, which access control method offers this kind of detailed, dynamic decision-making?

The access control method that offers detailed, dynamic decision-making based on factors like file owner, sensitivity, and time of day is Attribute-Based Access Control (ABAC). ABAC is a system that grants or denies access to resources by evaluating a set of attributes associated with the requesting entity (subject), the resource (object) being accessed, and the context (environment) of the access attempt. Instead of pre-assigning fixed permissions, ABAC defines policies that combine these attributes to make real-time decisions. Here’s how it works and why it fits: Attributes are simply characteristics or pieces of information. In ABAC, decisions are based on three main types of attributes: 1.
