Overview

Hey there! I’m Craig Peterson, your go-to cybersecurity consultant. Let’s chat about something crucial: setting up Duo Multi-Factor Authentication (MFA) with your Microsoft 365 email and Active Directory-controlled network computers. This is vital, especially if you’re handling Controlled Unclassified Information (CUI). So, let me share my favorite steps to get you secured and efficient!

Step 1: Check Your Prerequisites

First things first, ensure you have admin access to Microsoft 365 and Active Directory. This is important because you’ll need to make some changes to these systems.

Step 2: Create a Duo Account

Next up, head over to Duo’s website(https://duo.com) and sign up. Why Duo? It’s more secure than SMS-based 2FA and super user-friendly.

Step 3: Integrate Duo with Active Directory

Here’s a key step: You’ll need to integrate Duo with your Active Directory. This can be a bit technical, but essentially, you’re linking Duo to your network to manage access securely.

Step 4: Set Up Duo with Microsoft 365

Now, let’s get Duo and Microsoft 365 talking to each other. You’ll do this through the admin panels of both Duo and Microsoft 365. It’s a step-by-step process where you’ll enter necessary information from one system into the other.

Step 5: Configure Policies and Groups

This part is especially important. Set up policies in Duo to control who has access to what. This ensures that only the right eyes see sensitive CUI.

Step 6: Enroll Users

Here’s a crucial step: Enrolling users into Duo. Each person in your organization will need to be added. This usually involves sending them an invite and having them follow the registration process on their device.

Step 7: Test Your Setup

Most importantly, don’t skip this! Test everything to ensure it works as expected. Try logging in to Microsoft 365 and accessing a computer on your network. Look for any hiccups in the process and troubleshoot as needed.

Step 8: Train Your Team

Finally, educate your team about using Duo with Microsoft 365 and Active Directory. Make it a friendly, informative session, emphasizing the importance of this step for security and compliance.

Remember:

• Keep the process transparent and involve your team.
• Provide clear instructions and support during the rollout.
• Regularly review and update your security settings.

By following these steps, you’re not just implementing a new system; you’re safeguarding your organization’s and clients’ information. It’s a crucial and responsible step that shows you’re committed to security and efficiency.
