Palo Alto Networks PAN-OS EDL Service

This integration provides External Dynamic List (EDL) as a service for the system indicators (Outbound feed). The feed content can then be sent to 3rd parties for improving their security alignment.

Use Cases


  1. Generate feeds to be used on PAN-OS as External Dynamic Lists.
  2. Create External Dynamic Lists (EDLs) of the IP addresses, URLs and domains used by ransomware, known APT groups, and active malware campaigns for tracking in AutoFocus.
  3. Create External Dynamic Lists to track IPs and URLs commonly used by Microsoft Office365 or CDNs and cloud services, or used as tor exit nodes.

Configure EDL on Demisto

  1. Navigate to Settings > Integrations > Servers & Services.
  2. Search for EDL.
  3. Click Add instance to create and configure a new integration instance.
ParameterDescriptionRequired
Indicator QueryThe query to run to update its list. To view expected results, you can run the following command from the Cortex XSOAR CLI !findIndicators query=<your query>False
EDL SizeMax amount of entries in the service instance.True
Update EDL On Demand OnlyWhen set to true, will only update the service indicators via the edl-update command.False
Refresh RateHow often to refresh the export indicators list (<number> <time unit>, e.g., 12 hours, 7 days, 3 months, 1 year)False
Listen PortBy default HTTP, Will run the External Dynamic List on this port from within Cortex XSOARTrue
Certificate (Required for HTTPS)Configure a certificate for the EDL instance. The certificate is provided by pasting its value into this field. Use only when accesing the EDL instance by port.False
Private Key (Required for HTTPS)Configure a private key. The private key is provided by pasting its value into this field. Use only when accesing the EDL instance by port.False
CredintialsSet user and password for accessing the EDL instance. (Only applicable when https is used and a certificate profile is configured on the pan-os edl object)False
Collapse IPsWhether to collapse IPs, and if so - to ranges or CIDRs.False
  1. Click Test to validate the URLs, token, and connection.

Access the EDL Service by Instance Name (HTTPS)

The route will be open without security hardening and might expose you to network risks.

To access the EDL service by instance name, make sure Instance execute external is enabled.

  1. In Cortex XSOAR, go to Settings > About > Troubleshooting.
  2. In the Server Configuration section, verify that the instance.execute.external key is set to true. If this key does not exist, click + Add Server Configuration and add the instance.execute.external and set the value to true. See this documentation for further information.
  3. In a web browser, go to https://<cortex-xsoar_address>/instance/execute/<instance_name> .

Commands

You can execute these commands from the Cortex XSOAR CLI as part of an automation, or in a playbook. After you successfully execute a command, a DBot message appears in the War Room with the command details.
