Supported Cortex XSOAR versions: 5.5.0 and later.
This integration provides External Dynamic List (EDL) as a service for system indicators (Outbound feed). The feed content can then be sent to 3rd parties for improving their security alignment.
PAN-OS EDL Management, this integration hosts the EDL on the Cortex XSOAR server. Follow these steps to migrate your EDLs.
- Convert existing EDL lists to indicators in Cortex XSOAR. This can be done automatically:
- Extract your EDL as a text file from the web server it's currently hosted on.
- Upload it as a file to the Playground and use the
- Go to the
Indicatorspage and filter to find all of the indicators you extracted from the text file.
- If needed, batch select the indicators and add a tag to the indicators you want to host as a specific EDL. Use this tag in the
Indicator Queryintegration parameter when configuring the integration. For example, if you want to create an allowed list of indicators and a blocked list of indicators.
- Edit the EDL object on the PAN-OS device to pull from the
PAN-OS EDL Serviceinstance, as explained in Access the EDL Service by Instance Name (HTTPS). You can edit the EDL object using the panorama-edit-edl command in the
Palo Alto Networks PAN-OSintegration.
- Commit and push the configuration from the Panorama device to its respective Firewalls using the PAN-OS Commit Configuration playbook.
- If you have a deployment with 100 firewalls or more, we recommend using your Panorama device and creating an EDL object there, which will be populated from the
PAN-OS EDL Service. Then push the EDL object to the respective firewalls.
- Follow the instructions in the rest of this guide to make sure that the PAN-OS device is connected to the EDL service.
- Generate feeds to be used on PAN-OS as External Dynamic Lists.
- 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.
- 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.
- Navigate to Settings > Integrations > Servers & Services.
- Search for EDL.
- Click Add instance to create and configure a new integration instance.
|Indicator Query||The query to run to update its list. To view expected results, you can run the following command from the Cortex XSOAR CLI ||False|
|EDL Size||Maximum number of entries in the service instance.||True|
|Update EDL On Demand Only||When set to true, will only update the service indicators via the edl-update command.||False|
|Refresh Rate||How often to refresh the export indicators list (<number> <time unit>, e.g., 12 hours, 7 days, 3 months, 1 year)||False|
|Listen Port||By default HTTP. Runs the External Dynamic List on this port from within Cortex XSOAR||True|
|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|
|Credentials||Set 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|
|Strip Ports from URLs||If selected, a URL that includes a port number will be reformatted to remove the port. For example, 'www.example.com:9999/path' would become 'www.example.com/path'.||False|
|PAN-OS URL Drop Invalid Entries||If selected, any URL entry that is not compliant with PAN-OS EDL URL format is dropped instead of being rewritten.||False|
|Add Comment To Empty EDL||If selected, add to an empty EDL the comment "# Empty EDL".||False|
|Collapse IPs||Whether to collapse IPs, and if so - to ranges or CIDRs.||False|
|XSOAR Indicator Page Size||Internal page size used when querying XSOAR for the EDL. By default, this value shouldn't be changed||False|
|NGINX Global Directives||NGINX global directives to be passed on the command line using the -g option. Each directive should end with ||False|
|NGINX Server Conf||NGINX server configuration. To be used instead of the default ||False|
|Advanced: Use Legacy Queries||Legacy Queries : When enabled, the integration will query the Server using full queries. Enable this query mode, if you've been instructed by Support, or you've encountered in the log errors of the form: ||False|
- Click Test to validate the URLs, token, and connection.
Note: The EDL is open to the same network to which the Cortex XSOAR Server is accessible. Make sure you are aware of the network risks - enabling strong authentication is highly recommended if the route is open to the public.
To access the EDL service by instance name, make sure Instance Execute External is enabled.
- In Cortex XSOAR, go to Settings > About > Troubleshooting.
- In the Server Configuration section, verify that the
instance.execute.external.<instance_name>key is set to
true. If this key does not exist, click + Add Server Configuration and add the
instance.execute.external.<instance_name>and set the value to
true. See this documentation for further information.
- In a web browser, go to
Use the following arguments in the URL to change the request:
|n||The maximum number of entries in the output. If no value is provided, will use the value specified in the List Size parameter configured in the instance configuration.|
|s||The starting entry index from which to export the indicators.|
|q||The query used to retrieve indicators from the system. Make sure to URL encode.|
|tr||Whether to collapse IPs. 0 - to not collapse, 1 - collapse to ranges or 2 - collapse to CIDRs|
|sp||If set, will strip ports off URLs, otherwise will ignore URLs with ports.|
|di||If set, will ignore urls which are not compliant with PAN-OS URL format instead of being re-written.|
|ce||If selected, add to an empty EDL the comment "# Empty EDL".|
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.
Updates values stored in the EDL (only available On-Demand).
|query||The query used to retrieve indicators from the system.||Required|
|edl_size||The maximum number of entries in the EDL. If no value is provided, will use the value specified in the EDL Size parameter configured in the instance configuration.||Optional|
|collapse_ips||Whether to collapse IPs, and if so - to ranges or CIDRs.||Optional|
|drop_invalids||If True, any URL entry that is not compliant with PAN-OS EDL URL format is dropped instead of being rewritten.||Optional|
|url_port_stripping||If set to True, a URL that includes a port number will be reformatted to remove the port. For example, 'www.example.com:9999/path' would become 'www.example.com/path'.||Optional|
