Introduction

In an era where cyber threats are increasingly sophisticated, Microsoft Security Copilot emerges as a pivotal AI-driven solution designed to bolster the efficiency of security professionals. This guide provides a detailed walkthrough for installing and configuring Microsoft Security Copilot on Windows 11, ensuring your system is fortified against potential threats.

Understanding Microsoft Security Copilot

Microsoft Security Copilot is a generative AI-powered security tool that enhances the capabilities of defenders by providing natural language assistance for tasks such as incident response, threat hunting, and posture management. It seamlessly integrates with Microsoft's security ecosystem, including Defender XDR, Sentinel, Intune, and Entra, as well as third-party tools like Red Canary and Jamf, offering a unified experience for security professionals.

Prerequisites

Before proceeding with the installation, ensure your environment meets the following requirements:

  • Azure Subscription: An active Azure subscription is mandatory to access Security Copilot. If you don't have one, you can sign up at Azure Portal.
  • Security Compute Units (SCUs): These units are essential for the operation of Security Copilot, billed on a provisioned capacity model. SCUs are charged hourly in discrete blocks, with a minimum charge of one hour. To optimize costs, it's advisable to make provisioning changes at the start of an hour.
  • Capacity Planning: Determine the number of SCUs required based on your organization's needs. The capacity dictates the processing power allocated to Security Copilot and influences billing.

Step 1: Provisioning Capacity

You can provision capacity through two methods: the Security Copilot portal or the Azure Portal.

Option A: Using the Security Copilot Portal

  1. Access the Portal: Navigate to Security Copilot and sign in with your credentials.
  2. Initiate Setup: Click on the "Get Started" option.
  3. Configure Capacity:
  • Azure Subscription: Select your Azure subscription.
  • Resource Group: Associate the capacity with an existing resource group.
  • Capacity Name: Assign a recognizable name to the capacity.

Step 2: Configuring Security Copilot

After provisioning, configure Security Copilot to establish a default environment.

  1. Role Requirements: Ensure you have a Security Administrator role or higher and are an Azure Owner or Contributor for the capacity resource.
  2. Associate Capacity: Link the provisioned capacity to Security Copilot through the portal.
  3. Data Storage Confirmation: Confirm where your data will be stored and click "Continue."
  4. Microsoft 365 Services: Review and continue through the Microsoft 365 services integration.
  5. Activity Recording: Choose whether to record administrative actions, user activities, and system responses, then continue.
  6. Data Sharing Options: Select your preferred data-sharing settings and proceed.
  7. Assign Roles: Determine which roles can access Security Copilot and continue.
  8. Finalize Configuration: Review the summary and click "Finish."

Best Practices
