## Summary of Palo Alto Networks firewall discovery

The ServiceNow Discovery application includes the Next-Generation Palo Alto Firewall pattern to identify Palo Alto Networks firewalls within your environment.
This pattern relies on SNMP calls and is part of the horizontal discovery process.
To effectively use this pattern, customers may need to update the Discovery and Service Mapping Patterns application from the ServiceNow Store.

## Prerequisites and Setup

* Ensure SNMP access is enabled on the Palo Alto firewall devices.
* Configure SNMP credentials in your ServiceNow instance for secure discovery.
* Add the SNMP system OID record specific to Palo Alto Networks devices within ServiceNow.
* Update the classifier and class to Palo Alto Firewall and Palo Alto Firewall Device respectively.
* Download and install the Firewall extension classes and the specific Next-Generation Palo Alto Firewall discovery pattern from the ServiceNow Store.
* Sync the discovery pattern with your MID Server to enable communication and data collection.

## Data Model and Collected Information

The discovery pattern introduces a new CI class **Palo Alto Firewall Device \[cmdbcifirewalldevicepaloalto\]** which extends existing firewall device classes. When Discovery runs, it populates the CMDB with detailed information from the firewall, including:

* IP address, serial number, fully qualified domain name (FQDN)
* Manufacturer, model ID, operational status
* Hardware OS and version, firmware version, and a short description

Additionally, related CIs such as Network Adapter, IP Address, and DNS Name are populated with relevant details like IP addresses, MAC addresses, netmasks, aliases, and DNS names linked to the Palo Alto firewall device.

## CI Relationships and References

The pattern establishes key relationships to accurately represent the network infrastructure, including:

* Palo Alto Firewall Device owns Network Adapters and IP Addresses.
* Palo Alto Firewall Device uses Router Interfaces.
* Network Adapters own IP Addresses.

These relationships, along with references such as serial numbers and configuration items, ensure a comprehensive and connected CMDB representation of your Palo Alto Networks firewalls.

## Benefits for ServiceNow Customers

By implementing this discovery pattern, ServiceNow customers can automatically populate and maintain an accurate CMDB of their Palo Alto Networks firewalls. This enhances visibility into firewall assets, supports operational status tracking, and improves network security management through up-to-date configuration data.  
The ServiceNow
Discovery application uses the Next-Generation Palo Alto Firewall pattern to find Palo Alto Networks firewalls. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.
The discovery pattern uses a set of SNMP calls to find the Palo Alto Networks firewalls. Discovery uses the pattern to run horizontal discovery.

## Palo Alto Networks firewall data model {#palo-alto-fw-discovery__section_data_model}

The Next-Generation Palo Alto Firewall pattern introduces the following CI class that extends an existing CMDB class.  
{#palo-alto-fw-discovery__table_extends_palo_alto__entry__2}

| CI class | Extends from |
|-|-|
| Palo Alto Firewall Device \[cmdb_ci_firewall_device_palo_alto\] | Firewall Device \[cmdb_ci_firewall_device\] |
[Table 1. CI class introduced by this pattern]

{#palo-alto-fw-discovery__table_extends_palo_alto}

## Prerequisites {#palo-alto-fw-discovery__section_jtr_bzm_slb}

* Ensure that your network firewall device has SNMP access.
* On the ServiceNow instance, configure SNMP credentials. For more information, see [SNMP credentials](https://www.servicenow.com/docs/access?context=c_SNMPCredentials&version=yokohama&pubname=yokohama-platform-security&ft:locale=en-US).
* Add the SNMP system OID record for the Palo Alto Networks device to the ServiceNow instance. Update the following:
  * Classifier: Palo Alto Firewall
  * Class: Palo Alto Firewall Device
  {#palo-alto-fw-discovery__ul_pxv_3zm_slb}
* Deploy the pattern as follows:
  1. Download and install [Firewall extension classes](https://www.servicenow.com/docs/access?context=cmdb-ci-class-models-fw&version=yokohama&pubname=yokohama-servicenow-platform&ft:locale=en-US) from the ServiceNow Store. The app adds the new CMDB classes required for network firewall discovery.
  2. Download and install the discovery pattern from the ServiceNow Store.
  3. Sync the pattern with the appropriate MID Server.
