Exploring Cerbos: A Deep Dive into Scalable Authorization Solutions

In the realm of software development, the issue of access control and permissions management stands as a critical pillar of security and functionality. As applications grow in complexity and scale, ensuring that the right users have access to the right resources becomes increasingly challenging. Enter Cerbos, an open-core, language-agnostic, and scalable authorization solution that simplifies the implementation and management of user permissions through context-aware access control policies. In this comprehensive exploration, we delve into the intricacies of Cerbos, understanding its core concepts, how it works, its key features, real-world applications, and much more.

Understanding Cerbos: A Primer

Cerbos serves as an authorization layer that seamlessly evolves with your product, empowering developers to define powerful, context-aware access control rules for application resources. At its heart, Cerbos enables the management of user permissions through intuitive YAML policies, facilitating straightforward deployment and management via Git-ops infrastructure. This approach ensures that access control policies can be versioned, reviewed, and audited alongside the application source code, fostering a holistic approach to security and compliance.

Key Concepts

Before delving deeper into Cerbos, it's crucial to grasp its fundamental concepts:

Principal: The entity seeking access, which could be a user, application, service, bot, or any other entity within the system.

Action: A specific task or operation that a principal can perform, ranging from basic CRUD operations to more specialized actions.

Resource: The entity or object that access is being controlled for, such as files, database records, or any other application-specific resource.

Policies: YAML files where access rules for each resource are defined, specifying which principals can perform which actions on specific resources under various conditions.

Cerbos PDP (Policy Decision Point): The stateless service responsible for executing policies and making access control decisions. It provides highly available APIs for evaluating policies and making dynamic access decisions in real-time.

How Cerbos Works

Cerbos operates seamlessly within your application architecture, offering APIs for evaluating access control policies and making access decisions. By integrating Cerbos PDP into your application infrastructure, you enable dynamic, context-aware authorization tailored to your specific use cases.
