What operator should be used to create a query linking AlertInfo, AlertEvidence, and DeviceLogonEvents tables in Microsoft 365 E5?

The correct operator for linking the AlertInfo, AlertEvidence, and DeviceLogonEvents tables in Microsoft 365 E5 is the join kind = inner. An inner join is used to combine rows from these tables based on a related column between them. When using an inner join, only the records that have matching values in both tables will be included in the result set.

In the context of security operations, this is particularly useful as it allows analysts to correlate alerts and evidence with logon events, providing a comprehensive view of security incidents. Utilizing the inner join helps ensure that your analysis only includes relevant data where a relationship exists, which enhances the accuracy of the investigation.

The union kind operator is used to combine the results of two or more queries and include all records from each query, which may not necessarily link the tables in the same way an inner join would. The evaluate hint.remote and search * options do not provide the means to appropriately connect the two tables for correlated analysis; rather, they serve different functions in querying data. Thus, the inner join is the appropriate choice for effectively linking the specified tables in this context.
