Tutorial / Cram Notes
Implementing integration for on-premises apps using the Azure AD Application Proxy involves a series of steps that allow organizations to take advantage of the secure remote access without the need for a VPN or additional hardware. Here is how you can design and implement this integration effectively:
Designing the Integration Architecture
Before implementing the Azure AD Application Proxy, it’s important to design an architecture that meets your organization’s needs. Consider the following:
- Application Requirements:
- Identify the on-premises applications that you want to make accessible remotely through Azure AD.
- Determine the authentication requirements of these applications.
- Network Configuration:
- Plan the network topology, ensuring you can install the Application Proxy connector within your internal network.
- Ensure the connector server can reach the Azure AD Application Proxy service in the cloud and the backend application.
- Security Considerations:
- Decide on the authentication method (e.g., Azure AD pre-authentication, passthrough, or integrated Windows authentication).
- Consider the security implications of publishing each application and enforce policies like Conditional Access and Multi-Factor Authentication accordingly.
Implementing Azure AD Application Proxy
Step 1: Install and Register the Azure AD Application Proxy Connector
- Download and install the Application Proxy connector on a server in your internal network.
- Register the connector with your Azure AD tenant by signing in with a global administrator account.
Step 2: Add an Enterprise Application in Azure AD
- Navigate to your Azure AD portal and go to “Enterprise applications.”
- Click “New application” and then select “On-premises application.”
Step 3: Configure the On-premises Application
- Fill out the details for the application:
- Name: Give the application a meaningful name.
- Internal URL: Enter the URL that users access within the corporate network.
- External URL: Choose the URL that users will access the application from outside the corporate network.
- Pre Authentication Method: Decide whether you want Azure AD to authenticate the user before accessing the application.
- Assign users or groups to the application by configuring the necessary permissions.
Step 4: Test the Application Access
- Once the application is configured, test accessing the application from outside the corporate network using the external URL.
- Verify that the authentication works as expected and that users can access the application functionality.
Step 5: Monitor and Maintain
- Regularly monitor the health of the Application Proxy service and the connectors.
- Ensure that the necessary security updates and patches are applied to the environment where the Application Proxy connector is installed.
Examples of On-premises Apps Suitable for Azure AD Application Proxy
- Internal SharePoint Sites: SharePoint sites that are typically only accessible within the corporate network can be published through Azure AD Application Proxy for secure remote access.
- Legacy Applications: Older applications that don’t support modern authentication protocols can be made securely available to remote users.
Comparison Between Azure AD Application Proxy and Traditional VPN Solutions
| Feature | Azure AD Application Proxy | Traditional VPN |
|---|---|---|
| Infrastructure Requirements | No additional infrastructure required; uses existing Azure AD | Requires VPN infrastructure |
| External Access | Secure remote access through an external URL | Requires a VPN connection |
| Pre-authentication | Optional Azure AD pre-authentication | Typically no pre-authentication |
| Conditional Access & MFA | Supports Azure AD Conditional Access and MFA | Depends on VPN solution |
| Application Visibility | Only published applications are accessible | Full network access |
| Ease of Deployment | Quick and easy to set up | Can be complex and time-consuming |
| Security | Built-in security features and compliance with Azure AD standards | Depends on VPN implementation |
In conclusion, using Azure AD Application Proxy for integrating on-premises applications provides a secure, easy-to-implement solution for remote access. It allows companies to leverage their existing Azure AD investments, simplify management, and enhance security posture with features like Conditional Access and Multi-Factor Authentication.
