How to Ensure that users don’t authenticate to Azure AD applications using legacy authentication protocols?
Legacy authentication protocols, such as Basic authentication, do not provide the same level of security as modern authentication protocols like OAuth 2.0. Here are some steps you can take to ensure that users don’t authenticate to Azure AD applications using legacy authentication protocols:
- Disable legacy authentication: In Azure AD, you can disable legacy authentication protocols at the organization level or for individual applications. Disabling these protocols ensures that users can only authenticate using modern authentication protocols.
- Use conditional access policies: Conditional access policies can be used to block legacy authentication for specific applications or user groups. This can help ensure that users are only using modern authentication protocols.
- Enable modern authentication: Enable modern authentication for all Azure AD applications that support it. This allows users to authenticate using modern authentication protocols like OAuth 2.0 and OpenID Connect.
- Monitor Azure AD sign-in logs: Monitor Azure AD sign-in logs to detect any instances of users authenticating using legacy authentication protocols. This can help you take action to prevent further use of these protocols.
- Educate users: Educate your users about the risks of using legacy authentication protocols and the importance of using modern authentication methods. Provide clear instructions on how to access applications using modern authentication protocols.
By taking these steps, you can help ensure that users don’t authenticate to Azure AD applications using legacy authentication protocols, which can help improve the security of your organization’s resources.
