Therefore, the Azure Sentinel version avoids the state machine and is much simpler to build and maintain. In this post, I will describe implicit correlation rules and implementing them using the KQL operator join.Note. find operator is substantially less efficient than column-specific text filtering. Whenever the columns are known, we recommend using the where operator. find will not function well when the workspace contains large number of tables and columns and the data volume that is being scanned is high and the time range of the query is high.
