Alert Summaries
Alert summaries are a Panther feature that will automatically help you instantly know the answers to the Who , What, Where questions when triaging matching events in a rule alert. This feature is extremely useful when a rule has generated large numbers of matching events making understanding the nature of the threat(s) difficult. The alert summaries provide a view over all of the matching events that are often sufficient to avoid manually reviewing each event individually.
When creating a rule there is the option to declare Summary Attributes (see lower right corner). When displaying an alert there is a Summary tab. Selecting the Summary tab will display the top five attributes for each declared Summary Attribute. You should pick attributes that will help you understand the nature of an alert at a glance.
For example, say we have written a rule to find "Sneaky" traffic hitting our load balancer. This rule runs against theAWS.ALB logs. If we pick the Panther standard field p_any_ip_addresses and userAgent, then when we view an alert we can quickly see the top five values in the matching events. This can significantly speed up alert triage.
Summary Attributes
In this example, the first summary is p_any_ip_addreses. Notice that when you click on a bar a Copy icon displays. Copying the attribute of interest can be very handy. For example, to paste into Indicator Search and view all hits for that attribute in your data lake.
Alert Summary 1
Clicking the arrow above the chart allows you to navigate to the next summary.
Alert Summary 2
The dropdown selector on the right allows you to jump to a particular summary.
If a rule does not have any Summary Attributes defined, then summaries will be computed for all the Panther standard p_any fields associated with the target log types.
