Month: 2025-07 — Key platform improvements unlocked measurable business value across OpenBAS by delivering feature-rich dashboards, enhanced visualizations, foundational data indexing, and stronger observability, while tightening stability for developer and operator workflows. Key features delivered include: Custom Dashboards Enhancements (association with exercises/scenarios, improved simulation parameter display, and richer filtering/pagination); Attack Visualization Enhancements (structural-mode results limit, inclusion of external IDs with attack patterns, and a legend for the horizontal bar chart); Simulation Indexing Backend (initial Elasticsearch type, repository fetch, and data mapping handler); Telemetry/Observability Configuration (OpenTelemetry with toggle support and non-global registration); and Stability and Reliability improvements (frontend library rollback to stable versions, enhanced Tanium client logging and executor error handling, and transactional lifecycle fixes). Additionally, a collection-level improvement was implemented to remove a default type in the CrowdStrike collector configuration to improve flexibility in OpenBAS projects.
