Authorization and access control are critical aspects of software systems. In a recent demo, our very own [Alex Olivier](https://www.linkedin.com/in/alexolivier/) sits down with [Alex Williams](https://www.linkedin.com/in/alexhwilliams4) to share valuable insights on these topics, and demonstrates the Cerbos access control decision engine.

### Key Takeaways:

* Exploring types of authorization: Alex delves into role-based access control (RBAC) and attribute-based access control (ABAC), explaining their differences and use cases.
* Addressing common challenges: He highlights complexity, scalability, and security as common challenges faced by developers when implementing authorization.
* Introducing a dedicated authorization service or layer: Alex advocates for using a dedicated authorization service or layer to tackle these challenges effectively.
