Security leaders want to understand their current detection posture so they can proactively identify high-priority gaps and remediate them in a prioritized manner. Gaining a federated or aggregated view across multiple SIEMs is essential for having an accurate understanding of your overall detection posture. But in a multi-SIEM environment consisting of Splunk + Microsoft Sentinel, for example, Microsoft security logs and alerts are sent to Sentinel (Defender for Endpoint, etc.) and all non-Microsoft telemetry (Proofpoint, Okta, CyberArk, Zscaler, Vectra, etc.) is sent to Splunk. Each of these log sources requires its own detections, which cover different TTPs in the MITRE ATT&CK framework.
Read this complimentary security research summary to learn how to:
- Gain a federated view of MITRE coverage and rule health across multiple SIEMs- Ensure consistent detections and log sources across multiple SIEM instances
- Automate SIEM migrations
- Reduce ingestion costs by migrating log sources to the most appropriate SIEM
