Learning Path 7 - Lab 1 - Exercise 2 - Create a Playbook

Lab scenario

Lab overview.

You’re a Security Operations Analyst working at a company that implemented Microsoft Sentinel. You must learn how to detect and mitigate threats using Microsoft Sentinel. Now, you want to respond and reMediate actions that can be run from Microsoft Sentinel as a routine.

With a playbook, you can help automate and orchestrate your threat response, integrate with other systems both internal and external, and can be set to run automatically in response to specific alerts or incidents, when triggered by an analytics rule or an automation rule, respectively.

Note: An interactive lab simulation is available that allows you to click through this lab at your own pace. You may find slight differences between the interactive simulation and the hosted lab, but the core concepts and ideas being demonstrated are the same.

Task 1: Create a Security Operations Center Team in Microsoft Teams

In this task, you’ll create a Microsoft Teams team for use in the lab.

  1. Log in to WIN1 virtual machine as Admin with the password: Pa55w.rd.

Task 2: Create a Playbook in Microsoft Sentinel

In this task, you’ll create a Logic App that is used as a Playbook in Microsoft Sentinel.

  1. In the Microsoft Edge browser, navigate to Microsoft Sentinel on GitHub.

  1. Scroll down and select the Solutions folder.

  2. Next select the SentinelSOARessentials folder, then the Playbooks folder.

  3. Select the Post-Message-Teams folder.

  4. In the readme.md box, scroll down to the Quick Deployment section, Deploy with incident trigger (recommended) and select the Deploy to Azure button.

  5. Make sure your Azure Subscription is selected.

  7. Leave (US) East US as the default value for Region.

  8. Rename the Playbook Name to “PostMessageTeams-OnIncident” and select Review + create.

  9. Now select Create.

    Note: Wait for the deployment to finish before proceeding to the next task.

Task 3: Update a Playbook in Microsoft Sentinel

In this task, you’ll update the new playbook you created with the proper connection information.

  1. In the Search bar of the Azure portal, type Sentinel, then select Microsoft Sentinel.

  2. Select your Microsoft Sentinel Workspace.
