What does Rule-Based Access Control (Rule-BAC) use to determine access on a system?

Rule-Based Access Control (Rule-BAC) utilizes a set of rules, restrictions, or filters to determine access to resources within a system. This model evaluates the conditions specified in these rules whenever a user attempts to access a resource, allowing for a dynamic and flexible approach to access management.

The rules can take various factors into account, such as time of day, location, and other attributes related to the user and the requested resource. This level of granularity enables organizations to enforce access policies that adapt to specific circumstances or security requirements, making it a more versatile method compared to static models.

In contrast to models that rely on predefined roles, a central authority, or static permissions, Rule-BAC's rule-driven approach ensures that access can be tailored to reflect an organization’s current policies and threat landscape, creating a more secure environment.
