By setting attributes with different combinations, you can efficiently limit access to particular resources. For example, by setting role = manager, IP = your corporate network, and department = marketing, you can ensure that only managers from the marketing department can access certain resources if only they log in from your corporate network.

Role-Based Access Control

Role-Based Access (RBAC) is an authorization mechanism that determines which resource actions users can take. By assigning users to different roles, RBAC makes handling user access simple for you. In turn, these roles describe a collection of permissions that can be executed by users in that category, such as reading ...
... access to a given file.

You will ensure everyone has access to what they need, and nothing more, by allocating members of each team to their respective groups based on their roles. This model works for monitoring very well, where you need to manage which groups in your monitoring tool have access to certain resources.

ABAC vs. RBAC: Advantages & Disadvantages

One key difference when it comes to ABAC vs. RBAC is their static versus dynamic nature. RBAC allows access based on roles that are typically fairly static within an entity. In contrast, ABAC relies on attributes that can be dynamic, changing when a user makes an attempt to access a resource from an unrecognized computer or IP address.

This takes us to each model's advantages and downsides: ABAC can be automated to change permissions, and less overall administration is needed once it is set up. When set up correctly, it's also stable. ABAC can be very nuanced and environment-specific in terms of downsides, and it can be difficult to scale complicated attribute sets. For compliance purposes, it is also difficult to audit; you have to verify each object against your access policy instead of simply testing what access a single user has.

On the other hand, RBAC is highly effective and can streamline the process of compliance. Although a degree of complexity comes with any sort of access control, RBAC is straightforward enough that you can see how people communicate with resources based on their roles. You can more easily monitor how sensitive data is accessed because its configuration is reasonably simple, which can lead to less breaches.
One big drawback of RBAC is that it can make management difficult if your organization has many different roles, each with its own complicated set of permissions. RBAC cannot be automated, unlike ABAC, so the more complicated your environment, the more manual the control of access management becomes and, thus, more prone to errors.

Conclusion

As with any security measure, when it comes to access control, it is necessary to analyze your organization's needs, selecting the model that allows you to better satisfy the concept of least privilege without hindering business operations. Concerning the ABAC vs. RBAC debate, it is advisable that enterprises should adopt an RBAC-ABAC hybrid approach, leveraging the strengths of both the mechanisms for efficient access management.
