Taking our authorization system to the next level! In this third part of our series, we're enhancing our Amazon Verified Permissions (AVP) solution with Attribute-Based Access Control (ABAC). By combining RBAC and ABAC, we get a powerful authorization system that can enforce fine-grained access based on user attributes and context - perfect for multi-tenant applications where access control needs to account for more than just roles.

As authorization needs evolve, managing access efficiently becomes even more crucial. In this follow-up post, we extend our Policy Decision Point (PDP) and Policy Enforcement Point (PEP) solution by introducing Amazon Verified Permissions (AVP) for fine-grained authorization. Instead of storing permissions in DynamoDB, we leverage AVP’s centralized policy engine and Cedar policy language to define and enforce access control dynamically.

Authorization is a critical part of securing cloud applications, and understanding the best practices for implementing it can make all the difference. In this post, we dig deep on the concepts of Policy Decision Points (PDPs) and Policy Enforcement Points (PEPs), and how they work together to manage user access efficiently. We dive into a serverless solution using AWS Lambda and API Gateway, implementing Role-Based Access Control (RBAC) for fine-grained access control based on Cognito User Groups. This solution ensures scalability, low latency, and efficient authorization in serverless environments.
