Supported External Dynamic Lists for Palo Alto Networks Next-Generation Firewall

The ServiceNow Palo Alto Networks Next-Generation Firewall integration supports External Dynamic Lists (EDLs) that accept IP, URL, and domain observables.

Supported EDLs and observables

An External Dynamic List is a text file that is hosted on an external web server, which for this integration is the ServiceNow AI Platform instance. The Palo Alto Networks Next-Generation Firewall can then import objects — IP addresses, URLs, domains — included in the list and enforce policy. To enforce policy on the EDL entries, the list is referenced in a policy rule or profile.

This integration supports three types of EDLs:

  • IP (This includes a single IP Address, as well as CIDR blocks (ranges) of addresses).
  • URL
  • Domain

The following table lists descriptions of the observables supported by this integration and example formats for each type.

ObservableExample formatsDescription
IP Address- 95.153.103.54 \(IPv4\) - \(IPv6\): 2001:00B8:130F:FE03:0000:09C0:080F:130BRepresents a single, distinct interface address.The integration supports IPv4, IPv6, and CIDR formats. Support for IP address observables includes CIDR \(Classless Inter-Domain Routing\) ranges, for example, 95.153.100.0/22. Note: An error message is displayed when you try to attach a single IP address to an EDL that you have already blocked as a part of a CIDR range. For example, the single address 95.153.103.54 is part of the CIDR range represented by 95.153.100.0/22 \(95.153.100.0-95.153.103.255\).
URL- www.example.com - www.example.com/article.html - example.com - \*.example.comWildcards are supported. The ServiceNow AI Platform reformats URL entries to comply with Palo Alto Networks EDL format requirements.
Domain- www.example.com - example.com - mail.example.comWildcards are not supported.
