A good practice when drilling down into the traffic log when the search starts off with little to no information, is to start from least specific and add filters to more specific. Since detection requires unsampled network connection logs, you should not on-board detection for environments which has multiple hosts behind a proxy and firewall/network sensor logs shows only proxy IP address as source or if you are doing aggregation at any stage of your data ingestion. Because we are monitoring with this profile, we need to set the action of the categories to "alert." AMS-required public endpoints as well as public endpoints for patching Windows and Linux hosts.
