A company with regional offices wants to identify unusual trends and hidden anomalies in event records from multiple locations. Which design choice best supports this objective?
Maintain logs in separate offices and let each team review its own data independently
Remove certain entries to lower storage costs and keep only minimal records
Send logs to a hosted service but avoid performing correlated reviews
Aggregate event data from all regions into a unified repository for collective review
Centralizing event data in one shared environment promotes correlation and analysis across all offices. Storing data locally in separate locations prevents recognition of patterns that span multiple regions. Removing valuable entries eliminates critical information used for analysis, and sending records to an outside provider without thorough review limits detection capabilities.
