## Summary of Palo Alto Networks firewall discovery

The ServiceNow Discovery application leverages the Next-Generation Palo Alto Firewall pattern to identify Palo Alto Networks firewalls within your environment.
This pattern performs horizontal discovery using SNMP queries to detect firewall devices and populate the Configuration Management Database (CMDB) with detailed information.
To use this feature effectively, ensure your network devices allow SNMP access and that appropriate SNMP credentials and system OID records are configured on your ServiceNow instance.

## Key Features

* **Discovery Pattern:** Utilizes SNMP calls for horizontal discovery of Palo Alto Networks firewalls.
* **CMDB Integration:** Introduces a new CI class *Palo Alto Firewall Device \[cmdbcifirewalldevicepaloalto\]* extending existing firewall device classes to accurately represent Palo Alto firewalls.
* **Data Collection:** Automatically captures key device details such as IP address, serial number, FQDN, manufacturer, model ID, operational status, hardware OS and version, description, and firmware version.
* **Network Components:** Discovers associated network adapters, IP addresses, and DNS names, establishing relationships between devices and their network interfaces.
* **CI Relationships and References:** Creates ownership and usage relationships between firewall devices, network adapters, IP addresses, and router interfaces to provide a comprehensive network topology view.
* **ServiceNow Store Apps:** Requires downloading and installing the Firewall extension classes and discovery pattern apps from the ServiceNow Store, and syncing them with the appropriate MID Server.

## Prerequisites and Setup

* Ensure SNMP access is enabled on Palo Alto Networks firewall devices.
* Configure SNMP credentials and add the Palo Alto Networks SNMP system OID in ServiceNow.
* Download and install the necessary Firewall extension classes and discovery pattern apps from the ServiceNow Store.
* Sync the discovery pattern with the MID Server to enable network scanning.

## Key Outcomes

By implementing this discovery pattern, ServiceNow customers can expect automated and accurate identification of Palo Alto Networks firewalls, enriched CMDB records with detailed device and network information, and clear mapping of relationships among firewalls, network adapters, IP addresses, and router interfaces. This enhances network visibility, supports effective configuration management, and lays the foundation for improved security and operational workflows.  
The ServiceNow
Discovery application uses the Next-Generation Palo Alto Firewall pattern to find Palo Alto Networks firewalls. Discovering some of these resources may 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.

## Request apps on the Store {#palo-alto-fw-discovery__section_crv_1zm_slb}

## 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.
