Automate DevOps Security in Defender for Cloud Recommendation Remediation
Automate DevOps Security in Defender for Cloud Recommendation Remediation Logic Apps are a workflow automation feature of Microsoft Defender for Cloud in which you can create and run automated workflows that integrate your apps, data, services, and systems. This blog walks through creating a Logic App that you can use to auto-remediate the DevOps security recommendation in Defender for Cloud called “GitHub repositories should have Dependabot scanning enabled” by enabling Dependabot on a GitHub repo. Security Operators will find this Logic App particularly useful because they do not need to be familiar with GitHub or login to GitHub to enable Dependabot scanning. Instead, SecOps can enable Dependabot open source dependency scanning remotely and on numerous repositories by using Logic App automation. Objectives: Create a Logic App to enable Dependabot in GitHub Create a PAT Token and secure it in Azure Key Vault Test the Logic App Prerequisites: Key Vault – for Personal Access Token secret Connector provisioned in MDC to your GitHub Source Code Management System Sample GitHub repository – with Dependabot disabled Create a Logic App to enable Dependabot on a GitHub repo Login to Azure and search for or click Logic Apps Click + Add Choose a Subscription and Resource group Enter a name for your Logic App Under Plan, choose Consumption Click Review + create Click Create Go to the Logic App you created and click Logic app designer in the left menu Click Blank Logic App In the search box, type Recommendation Choose When a Microsoft Defender for Cloud Recommendation is created or triggered Click + New step Type variable in the search box Choose Initialize variable For Name, type repo_name For Type, choose String Click + New step Type variable in the search box Choose Initialize variable For Name, type owner For Type, choose String Click + New step Type variable in the search box Choose Set variable For Name, choose repo_name from the dropdown menu For Value, click in the empty box In the Add dynamic content flyout, click Expression and type the following: first(skip(split(triggerBody()?['properties']?['resourceDetails']?['id'],'/'),12)) and click OK Click + New step Type variable in the search box Choose Set variable For Name, choose owner from the dropdown menu For Value, click in the empty box In the Add dynamic content flyout, click Expression and type the following: first(skip(split(triggerBody()?['properties']?['resourceDetails']?['id'],'/'),10)) and click OK For this Logic App to execute securely, you need a Personal Access Token (PAT) to use in the API request. Follow the steps here in the GitHub documentation to create a PAT: https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token Important: The PAT needs permissions to enable Dependabot—which requires Full control of private repositories After you create a PAT, this should be stored in a Key Vault to keep it secure and accessible by the Logic App. Add the PAT as a secret to your Key Vault. Click Save on the Logic App canvas. Navigate back to the Logic App Click Identity On the System assigned tab, set status to On Click Save, then Yes Click Azure role assignments Click + Add role assignment In Scope, choose Key Vault. In Subscription, choose the subscription with your Key Vault. In Resource, select the Key Vault. In Role, choose Key Vault Reader Click Save Navigate back to the Logic App Click Identity On the System assigned tab, copy the Object (principal) ID Navigate to your Key Vault Click Access policies Click + Create In the Secret permissions list, tick Get and List Click Next Paste the Object (principal) ID that you copied earlier in the Search by box Click the Identity and click Next Click Next, then click Create Click Add, then click Save Navigate back to the Logic App Click Edit to go to the Logic Apps Designer Click + New step Type key vault in the search box Choose Azure Key Vault, click Get secret Click Connect with managed identity Type a Connection name, then type your Key Vault name in the Vault name box Click Create Choose your secret from the Name of the secret dropdown list Click + New step Type HTTP in the search box and click HTTP In Method, choose PUT.

Automate SecOps to Developer Communication with DevOps Security in Defender for Cloud Logic Apps are a workflow automation feature of Microsoft Defender for Cloud (MDC) in which you can create and run automated workflows that integrate your apps, data, services, and systems. Customer feedback has been loud and clear—Security Teams need more efficient and effective ways to communicate directly with Development Teams about discovered security findings. This blog walks through creating a Logic App that Security Teams can use to automate communication of discovered security issues to Development Teams. The Logic App creates a Work Item in Azure DevOps (ADO) containing repository location, description, and remediation information from DevOps security in Defender for Cloud Recommendations that Developers can use to remediate the discovered security issue. Security Operators will find this Logic App particularly useful because they do not need to be familiar with Azure DevOps or even to login to Azure DevOps to create a Work Item for their Developers. Instead, SecOps can trigger a Logic App on an affected repository and create a Work Item for a Development Team to triage and remediate.
