Migrating from Role to Attribute-based Access Control


Grab has always regarded security as one of our top priorities; this is especially important for data platform teams. We need to control access to data and resources in order to protect our consumers and ensure compliance with various, continuously evolving security standards.

Additionally, we want to keep the process convenient, simple, and easily scalable for teams. However, as Grab continues to grow, we have more services and resources to manage and it becomes increasingly difficult to keep the process frictionless. That’s why we decided to move from Role-Based Access Control (RBAC) to Attribute-Based Access Control (ABAC) for our Kafka Control Plane (KCP).

In this article, you will learn how Grab’s streaming data platform team (Coban) deleted manual role and permission management of hundreds of roles and resources, and reduced operational overhead of requesting or approving permissions to zero by moving from RBAC to ABAC.
