Why you should enable Conditional Access policies to block legacy authentication

 

Enhance Your Microsoft 365 Security by Blocking Legacy Authentication

In the ever-evolving landscape of cybersecurity, safeguarding your organization's data and systems has never been more crucial. One of the significant vulnerabilities that many organizations still contend with is legacy authentication. These older methods of authentication lack modern security features, making them prime targets for cybercriminals.

A comprehensive guide on how to mitigate this risk can be found in the article "Enable Conditional Access policies to block legacy authentication." This article walks you through the steps necessary to enhance your Microsoft 365 security by disabling legacy authentication.

Why Is Legacy Authentication a Risk?

Microsoft 365 has made it clear: "Today, most compromising sign-in attempts come from legacy authentication. Older Office clients such as Office 2010 don’t support modern authentication and use legacy protocols such as IMAP, SMTP, and POP3. Legacy authentication does not support multifactor authentication (MFA). Even if an MFA policy is configured in your environment, bad actors can bypass these enforcements through legacy protocols."

User Impact: With this policy enabled, any users accessing apps that don't support modern authentication will no longer be able to access them.

Legacy authentication sends credentials like usernames and passwords in clear text, which means they can be easily intercepted. Modern authentication, on the other hand, supports advanced security features such as MFA and token-based protocols, significantly reducing the risk of unauthorized access.

Steps to Disable Legacy Authentication

The article provides a detailed, step-by-step guide on how to disable legacy authentication, either by enabling MFA or by creating a Conditional Access policy. Here’s a brief overview of how you can create a Conditional Access policy to block legacy authentication:

  1. Access the Microsoft Entra Admin Center:
    • Navigate to Protection > Conditional Access policy.
  2. Create a New Policy:
    • Click on "Create new policy".
  3. Configure the Policy:
    • Set the policy name to "Block Legacy Authentication".
    • Apply the policy to all users.
    • Target all cloud apps.
    • Configure the conditions to exclude Browser & Mobile apps and desktop clients.
    • Set the controls under grant to "Block".
    • Enable the policy and click "Create".

By following these steps, you can significantly bolster your organization's security posture by ensuring that legacy authentication methods are no longer a weak link in your defenses.
