Cortex XDR - Port Scan - Adjusted

This Playbook is part of the Cortex XDR by Palo Alto Networks Pack.#

Investigates a Cortex XDR incident containing internal port scan alerts. The playbook:

  • Syncs data with Cortex XDR.
  • Notifies management about a compromised host.
  • Escalates the incident in case of lateral movement alert detection.

The playbook is designed to run as a sub-playbook in 'Cortex XDR Incident Handling - v3 & Cortex XDR Alerts Handling'. It depends on the data from the parent playbooks and can not be used as a standalone version.


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


  • IP Enrichment - Internal - Generic v2


This playbook does not use any integrations.


  • SetAndHandleEmpty
  • IsIPInRanges
  • AssignAnalystToIncident


  • send-mail
