Third Annual Report on State of SIEM Detection Risk

This report is the third annual analysis focusing on the current state of detection coverage and use case management in enterprise Security Information and Event Management (SIEM) systems. It quantifies gaps in detection capabilities using the MITRE ATT&CK framework as a baseline. The findings indicate that enterprise SIEMs, on average, cover only 24% of the techniques outlined in MITRE ATT&CK v13, despite ingesting enough data to potentially cover 94%. The report highlights that 12% of detection rules are broken and will not trigger alerts due to issues such as misconfigured data sources. It emphasizes the need for organizations to improve their detection engineering processes rather than simply collecting more data. The report also discusses the challenges faced by security operations centers (SOCs) in maintaining effective detection capabilities amidst increasing complexity and constant changes in the threat landscape. Recommendations for best practices in detection posture management are provided to help organizations enhance their security monitoring efforts.
