Want to use the free Purple Knight tool to evaluate your Azure AD security posture? To run Purple Knight in your Azure AD environment, you need to create and update the app registration in Azure AD with a defined and consented set of application permissions for the Microsoft Graph. Semperis provides a PowerShell script that automates this process.
Created by Semperis Senior Solutions Architect and Product Manager Jorge de Almeida Pinto, the script requires two PowerShell modules: AzureAD and Az.Accounts. Also, the account that you use to create the app registration must be a Global Admin.
How does the script support Azure AD security?
The script automates these tasks:
Creates and updates the app registration in Azure AD for Purple Knight 1.5 to be able to scan for vulnerabilities in Azure AD
Deletes the app registration in Azure AD
Assigns the required Microsoft Graph application permissions and provides consent when creating or updating the app
Creates a client secret that by default is valid for one hour when creating or updating the app (if needed, you can provide a customer lifetime in days for the client secret)
Deletes all client secrets from the app registration in Azure AD
Displays the tenant ID, the application ID, the assigned and consented permissions, and the client secret to be used in the Purple Knight executable file
