Attribute-Based Access Control

SECURITY & COMPLIANCE

Attribute-Based Access Control (ABAC) is a dynamic access management model that grants or revokes permissions based on user attributes from Microsoft Entra ID and Active Directory.

Unlike traditional role-based models, ABAC does not rely on predefined roles. Instead, access is determined in real time by evaluating multiple attributes such as job title, department, and location. This ensures that users always have access to the right resources while reducing the risk of excessive permissions.

How It Works

ABAC dynamically applies attribute-driven rules to grant or revoke access without requiring manual group assignments. These rules are automatically managed in the backend of ServiceChanger, so you only need to decide which group is linked to each attribute.

The system synchronizes user attributes from Microsoft Entra ID, including:

• Job Title

• Department

• Location

These attributes are used to create dynamic access policies that automatically control user permissions across applications, files, and services.

Example: Access Without Static Groups

A finance analyst needs access to budget reports. Instead of adding them to a finance role or group manually, an ABAC rule grants access if:

• Job Title = Finance Analyst

• Department = Finance

If the user moves to another department, their finance access is revoked automatically.

Benefits of ABAC

✅ Access is granted dynamically based on a user’s real-time attributes, reducing manual updates. ✅ Prevents excessive access by ensuring users only get exactly what they need. ✅ Eliminates the complexity of managing multiple roles and groups. ✅ If a user’s attributes change (promotion, department transfer, relocation), their access is updated immediately.

Final Thoughts

ABAC offers a more flexible and scalable alternative to traditional role-based or group-based access control. By leveraging user attributes, ServiceChanger.com ensures that access control is automated, secure, and always up to date.

This approach minimizes IT workload, enhances security, and ensures compliance without manual intervention.
