# Azure Web Application Firewall Policy pattern-based discovery

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

-   **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.

-   **Verify the Microsoft Azure discovery prerequisites**

    For more information, see the prerequisites section in [Microsoft Azure Cloud discovery using patterns]().

-   **Remove resources from the Resource Inclusion List table**

    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]().

-   **Enable the relevant pattern**

    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]().

-   **Configure the Discovery schedule to support GovCloud**

    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]().


Discovery and Service Mapping Patterns application populates data in both CMDB and non-CMDB tables.

## Data stored in non-CMDB tables

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 **All** > **Configuration** > **Azure**. You can also search the navigation filter for the specific pattern name.

|Field|Description|
|-----|-----------|
|Object Id \[object\_id\]|The unique identifier of the resource.|
|Kind \[kind\]|The specific kind or variant of the resource.|
|DC Location \[location\]|The Azure region where the resource is deployed.|
|Resource Group \[resource\_group\]|The name of the resource group containing the resource.|
|Subscription Id \[subscription\_id\]|The subscription ID associated with the resource.|
|Tenant Id \[tenant\_id\]|The Azure Active Directory tenant ID associated with the resource.|
|Provisioning State \[provisioning\_state\]|The latest provisioning status of the resource.|
|Configuration Item \[configuration\_item\]|References the Web ACL \[cmdb\_ci\_web\_acl\] table.|
|Policy State \[policy\_state\]|The current state of the policy applied to the resource.|

## Data stored in CMDB tables

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

<table><thead><tr><th>

Description

</th></tr></thead><tbody><tr><td>

Object ID \[object\_id\]

</td><td>

The unique identifier of the resource.

</table>## CI relationships

The Azure - Web Application Firewall Policy - Extended Inventory\(LP\) pattern creates these relationships to support Azure Web Application Firewall Policy discovery.

|CI|Relationship|CI|
|---|------------|---|
|Cloud Load Balancer \[cmdb\_ci\_cloud\_load\_balancer\]|Protected by::Protects|Web ACL \[cmdb\_ci\_web\_acl\]|
|Resource Group \[cmdb\_ci\_resource\_group\]|Contains::Contained by|Web ACL \[cmdb\_ci\_web\_acl\]|
|Web ACL \[cmdb\_ci\_web\_acl\]|Hosted on::Hosts|Azure Datacenter \[cmdb\_ci\_azure\_datacenter\]|
|Azure Web Application Firewall - Policy \[cmdb\_azure\_web\_application\_firewall\_policy\]|References|Web ACL \[cmdb\_ci\_web\_acl\]|

## Azure tag discovery

The pattern collects tags and populates them in the Key Value \[cmdb\_key\_value\] table.

|Field|Description|
|-----|-----------|
|Key \[key\]|Tag name.|
|Value \[value\]|Tag value.|
