QuestDB Enterprise: Role-based Access Control Walkthrough

QuestDB Enterprise now offers Role-based Access Control (RBAC) to manage data access through a SQL-based syntax, addressing the growing need for secure data management in expanding datasets. This system allows administrators to efficiently assign and revoke permissions, ensuring users only have access to data relevant to their roles, such as allowing analysts like Alex to perform SELECT operations without risking data integrity. The tutorial illustrates the setup of RBAC with examples using Postgres Wire and InfluxDB Line Protocol, emphasizing the importance of security by recommending against default passwords and showcasing the flexibility of Access Control Lists (ACLs) in managing user groups and permissions. Various authentication methods, including password, JSON Web Keys (JWK), and REST API tokens, are supported, catering to different access scenarios and enhancing the security framework. Through this approach, QuestDB facilitates scalable and secure data management, allowing precise control over access permissions at multiple levels within the database system.
