Azure Logs

Connecting Azure logs to your Panther Console

Overview

Panther supports ingesting Azure audit and sign-in logs via common Data Transport options, like Azure Blob storage.

How to onboard Azure logs to Panther

You'll first create an Azure Blob Storage source in Panther, then configure Azure to export logs to that location.

Step 1: Create the Azure source in Panther

1. In the lefthand navigation bar of your Panther Console, click Configure > Log Sources.

2. Click Create New.

3. Search for “Azure,” then click its tile.

   • In the slide-out panel, the Transport Mechanism dropdown in the upper-right corner will be pre-populated with the Azure Blob Storage option.

4. Click Start Setup.

5. Follow Panther's instructions for configuring an Azure Blob Storage Source.

   • If during Step 2: Create required Azure infrastructure you choose to create your Azure resources manually (instead of using Terraform), skip the step to create an Azure container, as one will automatically be created in your storage account in Step 2, below.

Step 2: Export Azure logs to Azure Blob storage

To export Azure audit and sign-in logs to a Blob storage container:

1. Sign in to your Azure dashboard.

2. In the left-hand panel of the Azure Active Directory, click Audit logs.

3. Near the top of the page, click Export Data Settings.

   
4. Click Add Diagnostic Setting.

5. On the Diagnostic setting page, set the following values:

   • Diagnostic setting name: Enter a descriptive name.

   • Categories (under Logs): Select the following checkboxes:

     • AuditLogs

     • SignInLogs

     • NonInteractiveUserSignInLogs

     • ServicePrincipalSignInLogs

     • ManagedIdentitySignInLogs

   • Destination details: Select the Archive to a storage account checkbox, then select your destination Storage account.

     
6. In the upper left corner, click Save.

   • Audit and sign-in logs will now be saved to a Blob container in your storage account.

Step 3: Add role assignment to container

1. Click on your newly created container, then in the left-hand navigation bar, click Access Control (IAM).

2. Click +Add.

3. Click Add Role Assignment.

4. Search for "Storage Blob Data Reader" and select the matching role that populates.

5. Click on the Members tab.

6. Click +Select Members.

7. Search for the name of the registered app you created during the Create required Azure infrastructure process on Azure Blob Storage Source, and click Select.

8. Click Review+Assign.

Supported log types

Panther supports Azure audit and signin logs which are handled by the Azure.Audit schema.
