Building secure applications: Key insights on authentication and authorization from Cerbos and Microsoft Entra

At the heart of this piece is the differentiation between authentication and authorization - two terms often intertwined but fundamentally different in their roles within cybersecurity. Authentication verifies user identity, acting as the first line of defense against unauthorized access. Authorization, on the other hand, determines what an authenticated user is allowed to do, thereby controlling access to resources and data. This blog post, the first in a series of three, delves into the intricacies of choosing the right authorization approach, exploring both coupled and decoupled AuthN and AuthZ models. It provides a foundational understanding for developers and IT professionals on structuring their security protocols effectively.

Importance of navigating authentication and authorization

Understanding the nuances of authentication and authorization is paramount for anyone involved in software development and cybersecurity. The collaboration between Cerbos and Microsoft illustrates not only the theoretical underpinnings but also practical considerations in selecting and implementing these security measures. The blog offers a comprehensive guide to navigating the complexities of AuthN and AuthZ, making it an essential read for developers looking to bolster their applications' security.
