## Summary of Next-Generation Fortinet Network Firewall SNMP-based discovery

The Next Generation Fortinet Network Firewall SNMP-based discovery pattern in ServiceNow enables automated identification and data collection of Fortinet firewall devices using SNMP calls.
It is part of the Discovery and Service Mapping Patterns application and supports horizontal discovery of Fortinet firewalls to populate the Configuration Management Database (CMDB) with detailed device information.
This pattern requires up-to-date Discovery and Service Mapping Patterns and proper SNMP configuration on both the Fortinet devices and within ServiceNow.

Note that this SNMP-based method does not discover FortiGate Virtual Domains (VDOMs); for that, a REST-based discovery method is used instead.

## Prerequisites

* Ensure the Discovery and Service Mapping Patterns application is current.
* Confirm SNMP access is enabled on Fortinet firewall devices.
* Configure SNMP credentials within the ServiceNow instance.
* Add the Fortinet SNMP system OID record to ServiceNow to classify devices correctly.

## CI Classes and Data Model

The pattern introduces Fortinet-specific CI classes extending existing CMDB classes to accurately represent firewall clusters and devices:

* **Fortinet Firewall Cluster** \[cmdbcifirewallclusterfortinet\] extends Firewall Cluster.
* **Fortinet Firewall Device** \[cmdbcifirewalldevicefortinet\] extends Firewall Device.

Discovered data fields include hostname, fully qualified domain name, IP address, manufacturer, model number, firmware, hardware OS and version, serial number, operational status, and descriptive information.

Additional related CI classes such as IP Address, Network Adapter, and DNS Name capture network interface details and relationships.

## CI Relationships and References

The discovery process establishes key relationships to represent device ownership and network topology, such as:

* Fortinet Firewall Clusters hosting Fortinet Firewall Devices.
* Firewall Devices owning IP Addresses and Network Adapters.
* Network Adapters owning IP Addresses.
* Firewall Devices using Router Interfaces.

References link serial numbers and network interfaces back to the appropriate Fortinet Firewall Device records, supporting accurate configuration and dependency mapping.

## Practical Benefits for ServiceNow Customers

By using this SNMP-based discovery pattern, customers can automate the population of Fortinet firewall information into their CMDB, enabling improved visibility and management of network security devices. Proper configuration ensures accurate device identification and enriched data for operational and security workflows. Customers should consider REST-based discovery if they need to discover FortiGate VDOMs.  
The Discovery and Service Mapping Patterns application uses the Next Generation Fortinet Network Firewall pattern to find Fortinet firewalls through a series of SNMP calls. 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 Next Generation Fortinet Network Firewall pattern uses a set of SNMP calls to find the Fortinet firewalls. Discovery uses the pattern to run horizontal discovery.  
Note:  
Only the REST-based Fortinet firewall discovery method finds FortiGate VDOMs. The SNMP-based Fortinet firewall discovery method doesn't discover them. For information on REST-based Fortinet firewall and FortiGate Virtual Domains (VDOMs) discovery, see [Fortinet firewall and FortiGate VDOM REST-based discovery](https://www.servicenow.com/docs/RkAGAqxHMZ5_XbFupjOXLw "The Discovery and Service Mapping Patterns application uses the Next Generation Fortinet Network Firewall - REST pattern to find Fortinet firewalls through REST API calls. Additionally, the pattern extension VDOM Discovery finds FortiGate Virtual Domains (VDOMs). Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.").

## Fortinet Firewall data model {#fortinet-fw-discovery__section_data_model}

The Next Generation Fortinet Network Firewall pattern introduces the following CI classes that extend an existing CMDB class.

| CI class | Extends from |
|-|-|
| Fortinet Firewall Cluster \[cmdb_ci_firewall_cluster_fortinet\] | Firewall Cluster \[cmdb_ci_firewall_cluster\] |
| Fortinet Firewall Device \[cmdb_ci_firewall_device_fortinet\] | Firewall Device \[cmdb_ci_firewall_device\] |

## Prerequisites {#fortinet-fw-discovery__section_pgt_4xz_ykb}

Verify the applications are up to date
:
    * Discovery and Service Mapping Patterns
    * CMDB CI Class Models
    {#fortinet-fw-discovery__ul_k2z_q5n_tcc}

Ensure SNMP access
:   Ensure that your Fortinet firewall device has SNMP access.

Configure SNMP credentials
:   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 SNMP system OID record to ServiceNow instance
:   Add the SNMP system OID record for the Fortinet device to the ServiceNow instance. Update the following:

    * Classifier: Fortinet Firewall
    * Class: Fortinet Firewall Device
    {#fortinet-fw-discovery__ul_rxb_ysn_tcc}

Run a horizontal discovery
:   For more information, see [Running discoveries in your network](https://www.servicenow.com/docs/z1YAnBcRkarsV70KmkIhPw "You can run discoveries from schedules or scripts to create configuration items, define subnets, or to find resources in AWS and Azure clouds.").

## Data collected by Discovery during horizontal discovery {#fortinet-fw-discovery__section_bpg_qxz_ykb}

Discovery populates the data in the CMDB when running the Next Generation Fortinet Network Firewall Pattern.
