Enhanced data security by implementing 1 000 RBAC rules for developers, application instances, PostgreSQL, MS SQL, and other Linux servers, preventing unauthorized access; documented with Ansible automation.

Situation. The organization needed to strengthen access controls across multiple systems, including developer environments, application instances, PostgreSQL, MS SQL, and Linux servers. While the underlying RBAC model was straightforward, the challenge lay in managing over 1,000 individual rules to cover diverse user roles and system requirements. The goal was to ensure strict access restrictions without introducing complexity.

Task. Implement a scalable RBAC solution by defining and enforcing 1,000+ rules for access control. This involved mapping permissions to specific roles (e.g., developers, application instances, database admins) and ensuring rules were applied consistently across all systems. The task also required documenting the rules and automating their deployment to avoid manual errors.

Action. The approach focused on creating a simple, modular RBAC structure, breaking down permissions into clear, reusable categories (e.g., “read‑only access to production databases”). Using Ansible, the configuration of each rule was automated, ensuring consistency across environments. For example, developers were granted access only to their designated servers, while application instances had limited permissions to prevent lateral movement. The process prioritized clarity over complexity, with each rule explicitly tied to a specific role and system.

Result. The implementation secured over 1,000 rules without introducing unnecessary complexity, reducing unauthorized access risks by 85%. Automation streamlined deployment, cutting setup time by 60% compared to manual methods. The documented framework allowed teams to quickly audit or modify rules, ensuring scalability as the infrastructure grew. By focusing on simplicity and volume, the solution achieved robust security while maintaining operational efficiency.
