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.
|WhitelistedPorts||A list of comma-separated ports that should not be blocked even if used in an attack.||Optional|
|BlockAttackerIP||Determines whether attacking IPs should be automatically blocked using firewalls.||False||Optional|
|EmailAddressesToNotify||A list of comma-separated values of email addresses that should receive a notification about compromised hosts.||Optional|
|InternalIPRanges||A list of IP ranges to check the IP against. The list should be provided in CIDR notation, separated by commas. An example of a list of ranges would be: "172.16.0.0/12,10.0.0.0/8,192.168.0.0/16" (without quotes). If a list is not provided, will use default list provided in the IsIPInRanges script (the known IPv4 private address ranges).||Optional|
|RoleForEscalation||The name of the Cortex XSOAR role of the users that the incident can be escalated to in case of developments like lateral movement. If this input is left empty, no escalation will take place.||Optional|
|OnCall||Set to true to assign only the users that are currently on shift.||false||Optional|
|xdr_alert_id||Unique ID for the XDR alert.||Optional|
|InternalIPRange||Please use "InternalIPRanges" input instead.|
