“SIEM rules encode not only syntax, but also detection intent,” Ming Xu, lead author of the paper, told CSO. Different SIEM platforms implement distinct field schemas, query operators, aggregation behavior, and correlation logic, meaning rules rarely translate cleanly between vendors, he said.
Practitioners say the issue is becoming more common as enterprises adopt hybrid cloud environments and multi-vendor security stacks.
Why is SIEM rule translation difficult
“In large enterprises, the need to port or reuse detection rules across platforms is becoming increasingly common,” said Prashant Chaudhary, area vice president at Splunk India. Hybrid cloud adoption, mergers, compliance requirements, and multi-vendor environments are forcing SOC teams to work across disparate telemetry formats and detection frameworks, he said.
