Workflow automation of Microsoft Defender for Cloud plays a significant role in upgrading your security management capabilities. Automations in Microsoft Defender lets you respond to specific alerts automatically. By deploying automatons according to recommended practices, you can streamline security alert responses and regulatory compliance, increase the efficiency of your Security Operations Center, and save significant time.
1. Automating Workflow with Microsoft Defender
For automating workflows in Microsoft Defender, you need to first set up custom automation configurations. Each configuration is a single response action or a set of response actions such as changing the system status, sending an email, or provisioning security measures in response to a specific security alert.
Although Microsoft Defender offers a set of built-in automations for prevalent threats, you can also design custom configurations for your organization’s specific security needs.
Both built-in and custom automation configurations can be applied to security alerts based on their properties. For instance, you could apply a light-touch configuration with minimal remedial actions for low-severity alerts and a heavy-handed configuration for high-severity alerts.
2. Configuring Workflow Automation
After designing your automation configurations, you need to apply them to relevant security alerts. Applying a configuration involves defining its scope and setting up its conditions and actions.
When defining an automation’s scope, you consider its relevant subscriptions and resource groups. This tells Microsoft Defender in what contexts to apply the automation.
Specifying an automation’s conditions involves defining the specific criteria that an alert must meet for the automation to be launched. For instance, you could specify that an automation should be applied when an alert’s severity is ‘high’, its status is ‘active’, and its vendor is ‘Microsoft’.
Configuring an automation’s actions involves specifying the actions that Microsoft Defender should take when an alert meets the defined conditions. These actions could include changing the alert’s status to ‘resolved’, sending an email to a specified recipient, or launching a Logic App for complex remedial actions.
3. Example of Automation Configuration
To set up a configuration for addressing high-severity alerts, you would do the following:
- a. Scope Definition: Specify the relevant subscriptions and resource groups to which the automation should be applied.
- b. Condition Setting: Specify that the automation’s condition is when an alert’s severity is ‘high’, its status is ‘active’, and its vendor is ‘Microsoft’.
- c. Action Configuration: Specify that when the condition is met, the alert’s status should be changed to ‘resolved’, an email should be sent to the relevant Security Operations team, and a Logic App should be launched to investigate and remediate the threat.
When everything is configured correctly, this automation will respond to high-severity alerts from Microsoft automatically by marking them as ‘resolved’, notifying the Security Operations team, and operations specialist and initiating a Logic App to address the threats.
4. Monitoring Automation Results
Automation results can be viewed easily in the “Automations” page of the Microsoft Defender Security Center. This page provides an overview of the automations’ states and histories, and also gives you options for modifying or retiring existing automations.
Through the “Automations” page, you can quickly verify that your automations are functioning as expected, and if they are not, you can troubleshoot and improve them.
Conclusion
In conclusion, designing and configuring workflow automation in Microsoft Defender for Cloud empowers you to respond quickly and effectively to security alerts. So, it’s advisable for every SC-200 Microsoft Security Operations Analyst exam aspirant to understand these concepts thoroughly to enhance their skills in security operations and threat management.
Remember, practice is key. Try to replicate this example configuration in a non-production environment to better understand the process. This hands-on experience will reinforce the principles and techniques discussed in this post.
