MITRE ATT&CK® Tactics

Execution

Execution consists of techniques that result in adversary-controlled code running on a local or remote system. Techniques that run malicious code are often paired with techniques from all other tactics to achieve broader goals, like exploring a network or stealing data. For example, an adversary might use a remote access tool to run a PowerShell script that does Remote System Discovery.

SubPattern Definitions

SubPattern Name: tm_vision_one_alert

This is the named definition of the event query, this is important if multiple subpatterns are defined to distinguish them.

SubPattern Query

This is the query logic that matches incoming events

eventType="Trend_Vision_One_Alert" AND eventSeverity>=9

Group by Attributes

This defines how matching events are aggregated, only events with the same matching attribute values are grouped into one unique incident ID

alertIdStr,hostName,hostIpAddr,ruleName,categoryType,status,infoURL

Aggregate Constraint

This is most typically a numerical constraint that defines when the rule should trigger an incident

COUNT(*) >= 1

Incident Attribute Mapping

This section defines which fields in matching raw events should be mapped to the incident attributes in the resulting incident.

The available raw event attributes to map are limited to the group by attributes and the aggregate event constraint fields for each subpattern

 alertIdStr=tm_vision_one_alert.alertIdStr,
ruleName=tm_vision_one_alert.ruleName,
hostIpAddr=tm_vision_one_alert.hostIpAddr,
hostName=tm_vision_one_alert.hostName,
categoryType=tm_vision_one_alert.categoryType,
status=tm_vision_one_alert.status,
infoURL=tm_vision_one_alert.infoURL
