SIEMs cover less than 20 percent of attack techniques
Security information and event management (SIEM) systems used by enterprises only have detections for 38 (19 percent) of the 201 techniques covered in the MITRE ATT&CK v14 framework according to a new report.
CardinalOps analyzed more than 3,000 detection rules, 1.2 million log sources and hundreds of unique log source types from real-world SIEM instances across Splunk, Microsoft Sentinel, IBM QRadar, and Sumo Logic.
