In March 2025, Michael Coldenhove enhanced the elastic/elasticsearch repository by implementing Kibana Security Data Streams and Permissions Enhancement. He expanded the Kibana_system role permissions to include new data streams for AWS Security Hub and Wiz full posture findings, focusing on improving security telemetry and access control. Using Java and backend development skills, Michael integrated data streams architecture and role-based access control to strengthen governance and security posture visibility. The work addressed the need for faster threat detection and clearer compliance by securing access to sensitive security data, demonstrating a focused, in-depth approach to security management without addressing bug fixes this month.
