Testing With Production Data
The ability to maintain a test SIEM has been a challenge for most SOCs. Test environments are typically inadequate as SOC teams cannot rely on a limited dataset to develop and test new rules and automation. At the same time, organizations maintaining a sizeable up-to-date dataset for a development SIEM instance usually means duplicating logs, […]

Log Ingestion Lag in Cloud-Based SIEMs
Lag in log ingestion is a topic that comes up now and then in our Azure Sentinel design discussions with our customers. We even had concerns around the speed of light being a constrain for certain critical log sources. These would be valid for security controls designed to protect strategic infrastructure but one has to […]
