Azure Configuration

Create an application

1. Log on to Azure portal with an account that has the Global Administrator privileges.  

2. In the search bar, search for App Registrations and select it.

5. On the app Overview page, copy the Application (client) ID and Directory (tenant) ID for later use.  
    
    

Add Endpoint Access  

Once the application is created, one permission to the Graph API is needed to fetch the data. This section details how to configure and add permission to the required endpoints.   

Add Permissions  

From the Azure portal:  

1. Select the application registered in the previous step.

2. Under Manage, click API Permissions and then click Add a Permission, the Request API permissions window will appear.

   Simulation User Coverage	Application	AttackSimulation.Read.All
   Simulation Repeat Offenders	Application	AttackSimulation.Read.All
   Simulation Training User Coverage	Application	AttackSimulation.Read.All
   Attack Simulations	Application	AttackSimulation.Read.All

Troubleshooting Tips

• If you are facing an invalid client or unauthorized client error this might be possibly due to incorrect credentials. Ensure the client key, client secret and Tenant ID are pasted correctly. Since you cannot view the client secret after the 1st time, re-create it, paste it on a text editor to ensure no spaces or unexpected characters are included and reconfigure the DataBee feed.

• If you are facing a response code – 403 error, this might be possibly due to missing permission. Ensure that all the required permissions are granted correctly as per the above-mentioned steps.
