Defender for Cloud unified Vulnerability Assessment powered by Defender Vulnerability Management
We are thrilled to announce that Defender for Cloud is unifying our vulnerability assessment engine to Microsoft Defender Vulnerability Management (MDVM) across servers and containers. Security admins will benefit from Microsoft’s unmatched threat intelligence, breach likelihood predictions and business contexts to identify, assess, prioritize, and remediate vulnerabilities - making it an ideal tool for managing an expanded attack surface and reducing overall cloud risk posture.AZ-500: Microsoft Azure Security Technologies Study Guide
The AZ-500 certification provides professionals with the skills and knowledge needed to secure Azure infrastructure, services, and data. The exam covers identity and access management, data protection, platform security, and governance in Azure. Learners can prepare for the exam with Microsoft's self-paced curriculum, instructor-led course, and documentation. The certification measures the learner’s knowledge of managing, monitoring, and implementing security for resources in Azure, multi-cloud, and hybrid environments. Azure Firewall, Key Vault, and Azure Active Directory are some of the topics covered in the exam.Policy Distribution Dashboard for Microsoft Defender for Cloud
Understanding the current state of your environment is the first step towards improving its security posture. Microsoft Defender for Cloud is designed to strengthen the three pillars every enterprise relies on which is Protection, Detection & Response providing you CSPM & CWPP functionalities. In Defender for Cloud, the posture management features provide Visibility and hardening guidance and the central feature that enables you to achieve these goals is Secure Score. Defender for Cloud continually assesses your resources, subscriptions and organization for security issues, and it aggregates all the findings into a single score by providing you list of recommendations. Typically, these are gaping holes that need to be fixed ASAP, while some recommendations are more long-term or just less critical and some more critical. Current Challenge One of the questions we constantly get asked is, How do I ensure that the Security posture will not start deteriorating again after the fixes have been made (or) how do I ensure I apply guardrails at the beginning of deployment phase for every service in Azure. It is often the case that development teams have full control of their subscriptions/resources. As a result, the configurations start to drift. The cure is simple, we need to have a security baseline defined. Before you start reading about the proposed solution, it is important to understand, Defender for Cloud and Azure policies work together to help monitor and report on compliance in your environment. Like security policies, Defender for Cloud initiatives are also created in Azure Policy. You can use Azure policy to manage your policies, build initiatives, and assign initiatives to multiple subscriptions or for entire management groups. The default initiative automatically gets assigned to every subscription in Defender for Cloud and that is Azure Security Benchmark. Azure Security Benchmark (ASB) consolidates Microsoft security best practices in Azure. It’s a great resource for design decisions, and the controls are mapped to industry standards. We have also created a policy set in Azure which can be used for monitoring resource compliance against the baseline. This widely respected benchmark builds on the controls from the Center for Internet Security (CIS) and National Institute of Standards and Technology (NIST) with a focus on cloud-centric security. Almost every recommendation from Defender for Cloud has an underlying policy that is derived from a requirement in the benchmark. To learn about the built-in policies that are monitored by Defender for Cloud, check this out. Here you can find all the Azure Policy definitions in the Defender for Cloud category. Proposed Solution Up until now, there was no single view with which you could visualize all the policies you have assigned to monitor compliance of your environment. You had to browse through many different blades in Azure to assess and obtain this information. With this blog, I’m introducing you to a workbook that acts as a single pane of glass representing the policies and baselines across multiple subscriptions in Azure, in your environment as the first crucial step is to inventory and gain visibility. What’s in the Dashboard The new Policy Distribution Dashboard for Microsoft Defender for Cloud provides a unified view and deep visibility into the configuration of your overall policy structure in Azure. The dashboard is powered by Azure Resource Graph (ARG) queries and divided into different sections. The workbook can be edited, and all queries can be modified to meet your needs. The workbook provides different sections like: Initiatives that’s assigned to the subscriptions The recommendations that are exempted and that are policy disabled List of Custom policies Regulatory Compliance Assessment State Policies by effect Compliance by policy assignment How to Deploy The Policy Distribution Dashboard is available in the Microsoft Defender for Cloud GitHub Repo page, under Workbooks and can be accessed directly with its direct URL The workbook can be deployed quickly in the Azure Commercial and Gov cloud environments by clicking the respective “Deploy to Azure” buttons on the workbook page. How to Use To use this dashboard, you need at least Reader permission at the subscription level. Assuming you have the required permissions, watch the screen capture below to learn about how to navigate through and use the dashboard. Conclusion The Policy Distribution dashboard provides valuable information about your policy assignments and it’s status. The workbook is available to all customers free of charge and does not require you to be a paid customer of Microsoft Defender for Cloud.

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. In URI, type https://api.github.com/repos///vulnerability-alerts. Put your cursor after repos/ and in the dynamic content click owner Move after the next / and click repo_name from the dynamic content In Headers, for Enter key type Accept and for Enter value type application/vnd.github+json In Headers, for Enter key type Authorization and for Enter value type token <space> click Value in the dynamic content Your HTTP step should now look like the following: Click Save to save the workflow Your no code Logic App is now complete and needs to be tested. Test the Logic App Navigate to Microsoft Defender for Cloud Click Recommendations Expand Enable enhanced security features, click GitHub repositories should have Dependabot enabled Expand Affected resources, tick a GitHub repository Click Trigger logic app In the Selected subscription dropdown, choose the Subscription that contains the Logic App Tick the box next to the Logic app Click Trigger Now let’s verify that Dependabot has been enabled Navigate to the GitHub repository that did not have Dependabot enabled Click Settings Click Code security and analysis You should now see that Dependabot alerts is enabled Conclusion To review, we’ve walked through creating a Logic App to auto-remediate the MDC recommendation: “GitHub repositories should have Dependabot scanning enabled” by enabling Dependabot on a GitHub repo. This helps harden the security on your organization’s GitHub repositories and provides Security Operators with visibility into your organization’s open source dependencies via Dependabot scanning findings.
