## Summary of Azure Web Application Firewall Policy pattern-based discovery

The Azure Web Application Firewall (WAF) Policy pattern-based discovery in ServiceNow identifies and maps Azure WAF policies within your cloud environment.
This discovery is part of the Discovery and Service Mapping Patterns application, which requires proper permissions and configuration to effectively detect Azure services and populate both CMDB and non-CMDB tables with relevant data about Azure WAF policies.
Show full answer Show less  

## Key Requirements and Configuration

* **REST API Permissions:** Ensure the user permissions required for discovery are granted by referencing the Cloud Discovery patterns spreadsheet, which includes pattern names, CI classes, and vendor documentation links.
* **Microsoft Azure Prerequisites:** Follow the Microsoft Azure Cloud discovery prerequisites for successful discovery.
* **Resource Inclusion List:** Verify the Azure WAF resources are not listed in the Resource Inclusion List table to prevent duplicate discovery.
* **Pattern Activation:** The Azure WAF Policy pattern is disabled by default and must be enabled. Pattern updates no longer count as customizations, so patterns reset to the latest version after upgrades while retaining their last active status.
* **Discovery Schedule for GovCloud:** Use the appropriate datacenter URL when setting up Azure service accounts to discover Azure GovCloud (US) accounts.

## Data Storage and Tables

* **Non-CMDB Data:** The discovery populates non-CMDB Azure tables when running the Azure - Web Application Firewall Policy - Extended Inventory pattern. These can be accessed via the ServiceNow navigation under Configuration \> Azure.
* **CMDB Data:** The same pattern populates CMDB tables with detailed WAF policy information, including policy state, provisioning state, and relationships with other configuration items.

## Key Fields and Relationships

* The **Azure Web Application Firewall - Policy** table tracks resource identifiers, deployment location, subscription and tenant IDs, provisioning status, and policy state.
* The **Web ACL** CMDB table stores WAF policy details such as name, location, default action mode (allow/block or detect/log), installation and operational status, and resource description.
* CI relationships establish links between WAF policies, web ACLs, resource groups, cloud load balancers, and Azure datacenters to provide a comprehensive view of dependencies and hosting environments.

## Azure Tag Discovery

The pattern also collects Azure resource tags and stores them in the Key Value table, capturing both tag names and their corresponding values to enhance resource metadata management.  
Discovery and Service Mapping Patterns finds Azure services on your cloud environment. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

## Pattern-based discovery and mapping requirements {#azure-web-app-firewall-policy__selection_ipy_53n_jfc}

Verify the REST API permissions
:   Download the [Cloud Discovery patterns spreadsheet](https://downloads.docs.servicenow.com/resource/enus/api/servicenow-discovery-patterns-api-details.xlsx) so you can grant user permissions required for running the Discovery patterns. In addition to permissions, the spreadsheet also includes useful information such as pattern names, types, CI Classes, and links to vendor documentation. New patterns are available quarterly, so check periodically to be sure you have the latest version of the spreadsheet.{#azure-web-app-firewall-policy__cloud-discovery-api-ph-short-prereq}

Verify the Microsoft Azure discovery prerequisites{#azure-web-app-firewall-policy__verify-azure-discovery-prerequisites-dlentry}
:   For more information, see the prerequisites section in [Microsoft Azure Cloud discovery using patterns](https://www.servicenow.com/docs/e2521~KHAw8EO7j1nC9QMA "Discovery uses multiple patterns to discover components of the Microsoft Azure Cloud deployment during horizontal discovery. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.").

Remove resources from the Resource Inclusion List table{#azure-web-app-firewall-policy__remove-resource-inclusion-list-azure}
:   Verify that the relevant resource isn't listed in the Resource Inclusion List \[sa_cloud_inventory_resource_whitelist\] table to avoid duplicate discovery. For more information on removing resources from the Resource
    Inclusion List, see [Microsoft Azure resource inventory discovery](https://www.servicenow.com/docs/tO3nNqXv4zOe7q99krvAnA "The ServiceNow Discovery application uses the Azure Resource Inventory (LP) pattern to find resources available through Azure that don’t have a dedicated pattern. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.").

Enable the relevant pattern{#azure-web-app-firewall-policy__enable-pattern-reuse-dlentry}
:   The pattern for this service is disabled by default. Starting with Visibility Content version 6.28.0, activating or deactivating a pattern won't be considered a customization, and it will continue to receive updates. Patterns that were previously activated or deactivated will reset to the latest predefined version after upgrading while retaining the last active field value. For more information on enabling patterns, see [Activate a disabled pattern](https://www.servicenow.com/docs/aypCYVQdO8oFebLMLEI89g "If you want to use a pattern for discovery that's disabled by default, activate it manually.").{#azure-web-app-firewall-policy__activating-disabled-pattern-not-customization}

Configure the Discovery schedule to support GovCloud{#azure-web-app-firewall-policy__configure-govcloud-azure-dlentry}
:   Discovering Azure GovCloud (US) accounts requires using a datacenter URL when setting up an Azure service account. For more information, see [Set up Azure service accounts](https://www.servicenow.com/docs/XKQpJvxWTKNL58XCkRHVxA "Create and configure cloud service accounts at ServiceNow AI Platform for the corresponding Microsoft Azure accounts.").{#azure-web-app-firewall-policy__configure-govcloud-azure-dd}
{#azure-web-app-firewall-policy__configure-govcloud-azure-dd} Discovery and Service Mapping Patterns application populates data in both CMDB and non-CMDB tables.

## Data stored in non-CMDB tables {#azure-web-app-firewall-policy__section_aq4_qkq_hfc}

Discovery and Service Mapping Patterns application populates data in the non-CMDB table when running the Azure - Web Application Firewall Policy - Extended Inventory(LP) pattern.

You can review the non-CMDB
Azure tables by navigating to AllConfigurationAzure. You can also search the navigation filter for the specific pattern name.
