Summary
This solution brief outlines the Thales Policy-Based Authorization Manager (PBAM), which is part of the OneWelcome Identity Platform. It focuses on the implementation of Policy-Based Access Control (PBAC) to deliver dynamic authorization for enterprises. The document describes the challenges organizations face with traditional role-based access control (RBAC) models, particularly in cloud-native environments where authorization complexity increases. It details how PBAM enables fine-grained, auditable access control by defining access policies that are evaluated in real-time against identity and attribute sources. The brief also highlights key business benefits such as policy agility, consistent enforcement, audit readiness, reduced development overhead, and the implementation of Zero Standing Privileges. Furthermore, it explains the centralized management and distributed enforcement capabilities of PBAM, allowing organizations to enforce access policies across various layers of their technology stack without embedding authorization logic in application code. The document concludes by discussing target use cases for PBAM, including API authorization and data access control.
