CrowdStrike Falcon - SIEM ingestion Get Incident Data

This Playbook is part of the CrowdStrike Falcon Pack.#

Supported versions

Supported Cortex XSOAR versions: 6.5.0 and later.

This playbook handles incident ingestion from the SIEM. The user provides the field for the incident ID or detection ID as well as the field indicating whether the ingested item is an incident or detection. This playbook enables changing the severity scale in Cortex XSOAR as well as fetching CrowdStrike detections based on the CrowdStrike incident type.

Dependencies#

This playbook uses the following sub-playbooks, integrations, and scripts.

Playbook Inputs#


NameDescriptionDefault ValueRequired
SIEMincidentFieldForTypeThe incident field that determines if this is a detection or an incident.${incident.externalcategoryname}Optional
SIEMincidentFieldForIDThe incident field that contains the detection ID or incident ID.${incident.externalsystemid}Optional
ScaleToSetSeverityThe severity scale in the EDR.
For example, CrowdStrike uses values from 0 to 100
so the scale can be divided into ranges such as
0-20,21-40,41-60,61-80,81-100
0-20,21-40,41-60,61-80,81-100Optional
SeverityValuesMappingThe mapping from the EDR severity scale to the Cortex XSOAR severity scale.
For example:
0.5, 1, 2, 3,4
Possible values to use are 0,0.5, 1, 2, 3,4
which represent Unknown, Informational, Low, Medium, High, Critical.
0.5, 1, 2, 3,4Optional
OverrideSIEMSeverityWhether to set the severity according to the EDR severity scale and its mapping to Cortex XSOAR (True) or keep the original severity scale as mapped by the SIEM (False).FalseOptional
