Updating Enterprise Apps in the Background Using Single App Mode and Mobile Device Management (MDM)

Single App Mode Enterprise App Update

As a developer, managing updates for enterprise applications can be a complex task. When deploying kiosk applications to multiple devices using Single App Mode (SAM), updating the application in the background without user interaction is crucial for maintaining seamless performance and ensuring that only the latest version of the app is running on each device.

In this article, we’ll delve into the details of how to update an enterprise app installed via Mobile Device Management (MDM) in the background using Single App Mode. We’ll explore the challenges, solutions, and technical requirements involved in implementing such a feature.

Understanding Single App Mode

Single App Mode is a feature available on iPad devices that allows developers to distribute and manage iOS applications within a single, sandboxed environment. This mode provides several benefits, including:

Improved security: By isolating the application from other system components, SAM reduces the attack surface and minimizes the risk of malicious activity.
Simplified management: SAM enables developers to deploy and update applications without requiring user intervention, making it easier to manage large fleets of devices.

Enterprise Distribution Process

When distributing an enterprise app using the Enterprise Distribution Process, the application is installed on the device using MDM. This process typically involves:

Creating a certificate signing request (CSR) for the app
Submitting the CSR to the MDM server for verification and validation
Receiving a signed certificate from the MDM server
Installing the app on the device using the signed certificate

This process ensures that only authorized applications are installed on devices, providing an additional layer of security.

Background Update Challenges

Updating an enterprise app in the background without user input presents several challenges:

App Store Guidelines: Apple’s App Store Guidelines prohibit apps from updating themselves in the background without user interaction. This means that developers must find alternative methods to update their applications.
Security Concerns: Allowing an app to update itself in the background raises security concerns, as it may potentially expose the device or application to malicious activity.

Solutions and Workarounds

Despite these challenges, there are several solutions and workarounds that can be used to update an enterprise app installed via MDM in the background using Single App Mode:

Custom Update Mechanism: Developers can create a custom update mechanism that uses the MDM server to push updates to the device without requiring user input. This typically involves creating a script or tool that communicates with the MDM server to retrieve and install updates.
App-Specific Update Tools: Some MDM solutions provide app-specific update tools that allow developers to manage updates for their applications. These tools can be used to push updates to devices in the background without requiring user interaction.
Enterprise App Management Platforms: Certain enterprise app management platforms, such as MobileIron or VMware Workspace ONE, offer built-in support for background updates. These platforms provide a centralized management interface that allows administrators to manage updates for their applications.

Technical Requirements

To update an enterprise app installed via MDM in the background using Single App Mode, several technical requirements must be met:

MDM Support: The MDM solution used must support app-specific updates or have built-in support for background updates.
Custom Update Mechanism: A custom update mechanism must be created to communicate with the MDM server and retrieve updates.
Device Configuration: Devices must be configured to allow the app to update itself in the background. This typically involves setting up a custom configuration profile that enables the update mechanism.

Best Practices

When implementing background updates for enterprise apps, several best practices should be followed:

Test Thoroughly: Ensure that the update mechanism is thoroughly tested to avoid any issues or errors.
Validate Updates: Validate updates before pushing them to devices to ensure they are legitimate and safe.
Monitor Devices: Monitor devices after updating to ensure that the update was successful and that there were no issues.

Conclusion

Updating an enterprise app installed via MDM in the background using Single App Mode is a complex task that requires careful consideration of several technical requirements and best practices. By understanding the challenges, solutions, and workarounds involved, developers can implement efficient and effective updates that improve the overall user experience.
