## Summary of Palo Alto Networks Firewall Discovery

The ServiceNow Discovery application leverages the Next-Generation Palo Alto Firewall pattern to detect Palo Alto Networks firewalls in your environment.
This discovery uses SNMP calls to perform horizontal discovery, collecting detailed device information and populating the Configuration Management Database (CMDB) with accurate firewall data.
To enable this, customers may need to update to the latest Discovery and Service Mapping Patterns application from the ServiceNow Store.

## Prerequisites and Setup

* Ensure the Palo Alto firewall devices have SNMP access enabled.
* Configure SNMP credentials on your ServiceNow instance.
* Add the SNMP system OID record specific to Palo Alto Networks devices.
* Update the classifier and class for Palo Alto Firewall Device in your instance.
* Download and install the required Firewall extension classes and the discovery pattern from the ServiceNow Store.
* Synchronize the discovery pattern with the appropriate MID Server.

## Data Model and Collected Information

The discovery pattern introduces a new CMDB CI class **Palo Alto Firewall Device \[cmdbcifirewalldevicepaloalto\]**, extending the generic firewall device class. It collects key device attributes such as:

* IP address, serial number, fully qualified domain name (FQDN), and manufacturer
* Model ID, operational status, hardware OS and its version
* Firmware version and a short description

In addition, related CIs such as Network Adapter, IP Address, and DNS Name are populated with relevant details like MAC address, netmask, and aliases, all linked back to the Palo Alto Firewall Device.

## CI Relationships and References

The pattern establishes important CI relationships to model the firewall environment accurately, including:

* Palo Alto Firewall Devices owning Network Adapters and IP Addresses
* Network Adapters owning IP Addresses
* Palo Alto Firewall Devices using Router Interfaces

References link CI fields such as serial numbers, configuration items, and NICs to their corresponding tables, enhancing CMDB integrity and enabling comprehensive network topology mapping.

## Benefits for ServiceNow Customers

By implementing this discovery pattern, customers gain automated, accurate identification and classification of Palo Alto Networks firewalls within their CMDB. This supports improved asset management, security posture visibility, and integration with IT operations workflows. Keeping the discovery patterns and extensions up to date ensures optimal detection and data accuracy.  
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=brazil&pubname=brazil-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=brazil&pubname=brazil-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.
