One I find useful that is not in the list above is an alteration of your filters in one simple thing - a Source or Destination address = (addr.src in x.x.x.x) or (addr.dst in x.x.x.x), Traffic for a specific security policy rule = (rule eq 'Rule name'). This article will discuss the use case of detecting network beaconing via intra-request time delta patterns using KQL (Kusto query language) in Azure Sentinel. Hi Glenn, sorry about that - I did not test them but wrote them from my head.
