Implementing Azure CBA for Enhanced Security

Azure CBA, or Cloud Backup and Archive, is a game-changer for businesses looking to enhance their security. With Azure CBA, you can protect your data from cyber threats and ensure business continuity in the event of a disaster.

By implementing Azure CBA, you can reduce your backup window from hours to minutes, and even seconds. This is because Azure CBA leverages the scalability and reliability of the Microsoft Azure cloud platform.

Azure CBA also provides advanced security features, such as encryption and access controls, to safeguard your data. This means you can rest assured that your data is protected from unauthorized access and tampering.

With Azure CBA, you can also ensure compliance with regulatory requirements, such as GDPR and HIPAA. This is because Azure CBA provides detailed auditing and reporting capabilities to help you track data access and modifications.

To successfully follow this guide, you'll need to meet some essential prerequisites. Active Directory must be synchronized with Azure Active Directory (AAD) to ensure a seamless integration.

This synchronization is crucial for authentication and authorization purposes. You can check if your directories are synchronized by verifying the status in the Azure portal.

Here are the specific prerequisites you'll need to meet:

Having these prerequisites in place will ensure a smooth experience as you follow the guide.

Configuring Certificate-Based Authentication (CBA) in Azure can be a bit of a process, but don't worry, I've got you covered.

To start, you'll need to configure your CBA settings in the Microsoft Entra admin center. There are four major steps involved: configuring your trusted CA certificates, authentication bindings, user account bindings, and enabling CBA as an authentication method.

You can configure your trusted CA certificates by uploading the exported CA certificate to Azure, just like you would in the regular Azure portal.

To configure your authentication bindings, you'll need to determine the strength of authentication to either a single factor or multifactor. You can change the default value from single factor to multifactor and configure custom policy rules by mapping to issuer Subject, policy OID, or combining Issuer Subject and Policy OID fields in the certificate.

The authentication binding policy helps determine the strength of authentication to either a single factor or multifactor. An Authentication Policy Administrator can change the default value from single factor to multifactor and configure custom policy rules by mapping to issuer Subject, policy OID, or combining Issuer Subject and Policy OID fields in the certificate.

Here are the steps to configure the authentication binding policy:

Note that you can also set up custom authentication binding rules by following the relevant Microsoft documentation.

To configure user account bindings, you'll need to create a username binding policy. This involves selecting one of the X.509 certificate fields to bind with one of the user attributes.

Here are the steps to configure the username binding policy:

Finally, to enable CBA and configure user bindings, you'll need to navigate to the Authentication methods section in the Entra admin center. From there, you can toggle the ENABLE toggle to Yes and configure scope (All users).

Certificate-Based Authentication is a secure way to log in to Azure, using X.509 certificates issued from a trusted Public Key Infrastructure (PKI). This method eliminates the need for federated certificate-based authentication, which requires Active Directory Federation Services (ADFS) deployment.

Microsoft Entra ID allows direct authentication with X.509 certificates, providing phishing-resistant login that can be verified using Conditional Access policies. Unlike ADFS, this method offers tighter security, as login signals cannot be spoofed or the infrastructure hacked.

To enable Certificate-Based Authentication, you need to configure your trusted CA certificates, authentication bindings, user account bindings, and enable CBA as an authentication method. This can be done in the Microsoft Entra admin center.

Here are the four major steps involved in configuring CBA:

Some benefits of Certificate-Based Authentication include:

Certificate-Based Authentication also supports web resources protected by Azure AD, and can be used with YubiKey smart cards. This method provides strong two-factor authentication, using both a knowledge factor (PIN) and a possession factor (the YubiKey).

Troubleshooting can be a challenge, but Microsoft Entra has got you covered. You can find common error codes and solutions in the Microsoft Entra authentication and authorization error codes.

If you're encountering issues, start by checking the error codes. The AADSTS1001009 error code is a common one, and it means that the certificate is unable to validate the user claim due to a tenant policy.

To resolve this, you can refer to the Microsoft Entra documentation for solutions to common error codes.

Troubleshooting can be a frustrating process, but there are steps you can take to resolve common issues. Sometimes, all it takes is knowing where to look for solutions.

If you're experiencing errors with Microsoft Entra authentication and authorization, check the Microsoft Entra authentication and authorization error codes for common error codes and solutions.

When encountering the AADSTS1001009 error code, the issue is likely due to a certificate not being able to validate the user claim, as required by tenant policy.

To resolve this, you can check the Microsoft Entra authentication and authorization error codes for a solution to this specific error code.

Verification is a crucial step in troubleshooting. You are now logged in to a cloud resource with a smartcard, as demonstrated in the example.

To set up Azure CBA on your tenant, you'll first need to enable certificate-based authentication. This can be done by signing in to the Microsoft Entra admin center as at least an Authentication Policy Administrator.

Once you've enabled CBA, all users in the tenant will see the option to sign in with a certificate. However, only users who are enabled for certificate-based authentication will be able to authenticate using the X.509 certificate.

To enable users for certificate-based authentication, you'll need to follow the steps outlined in the Microsoft Entra admin center. This involves selecting Certificate-based authentication under Protection > Authentication methods > Certificate-Based Authentication.

To enable certificate-based authentication in your tenant, you'll need to sign in to the Microsoft Entra admin center with at least an Authentication Policy Administrator role.

You'll then need to browse to Protection > Authentication methods > Certificate-Based Authentication and select Certificate-based authentication.

Once you've done this, all users in the tenant will see the option to sign in with a certificate. However, only users who are enabled for certificate-based authentication will be able to authenticate using the X.509 certificate.

Microsoft Entra Hybrid joined devices are just one option, but agencies can achieve similar functionality with Microsoft Entra joined or by using a different vendor's Mobile Device Management product.

For agencies with Microsoft Entra native devices, the same steps apply and can be deployed today.

Agencies using a different vendor's Mobile Device Management product should check with their vendor to see how their compliant device signal can be used in Microsoft Entra ID through an API or other method.

A joined device guarantees an enterprise policy manages the device, which is essential for security under the Zero Trust model.

To set up Azure AD CBA on iOS devices with a YubiKey, you'll need to use the Yubico Authenticator App to copy the YubiKey's public certificate into the iOS keychain. This ensures the private part of the smartcard certificate never leaves the YubiKey.

Users can initiate the authentication flow by selecting the YubiKey certificate from the certificate picker. They can either insert the YubiKey or tap an NFC-enabled YubiKey to continue.

To complete the process, users will enter their PIN via the YubiKey Authenticator and finish the authentication flow. This provides an additional layer of security for your Azure AD account.

If iOS doesn't recognize the YubiKey, you can use the Yubico Authenticator App to copy the public certificate into the iOS keychain.
