What is the focus of Attribute-Based Access Control?

The focus of Attribute-Based Access Control (ABAC) is on user attributes and contextual factors. This model evaluates a wide range of characteristics associated with users and their environments before granting access to resources. It uses various attributes such as the user's role, their location, the time of access, and other relevant contextual information to make decisions about whether access should be permitted.

This flexibility allows ABAC to adapt to dynamic situations and complex environments, providing a more nuanced and granular approach to security compared to other models. For example, a user might have the role of a manager but may only have access to sensitive information when working remotely during business hours. By focusing on attributes rather than fixed roles or predefined rules, ABAC enables organizations to implement more precise and context-aware access control policies.

In contrast, other approaches like role-based access control focus strictly on the roles individuals play within an organization, which can be limiting in environments that require more personalized access criteria. Similarly, predefined rules may not take contextual factors into account, potentially leading to insufficient or excessive access.
