How does Intune ensure secure mobile application access?

Intune ensures secure mobile application access primarily through application protection policies. These policies are designed to safeguard applications and data on both managed and unmanaged devices. They play a critical role in securing access by enforcing various restrictions and security measures directly on applications.

For instance, application protection policies may require that users authenticate themselves through various means, such as a PIN or biometric data, before accessing sensitive applications. They can also restrict the ability to copy or paste data between applications or control how data is shared. In this way, even if an application is installed on an unmanaged device, the data within it can still be protected, helping prevent data breaches and unauthorized access.

The other concepts, while related to security, do not specifically ensure secure mobile application access to the same extent as application protection policies. VPN configurations enable secure connections to corporate resources but do not inherently protect applications themselves. Restricting internet access might limit exposure to threats, but it doesn't directly secure the applications. Firewall settings may help to manage network traffic but are not specific to application-level security. Thus, application protection policies are integral to safeguarding mobile application access in a comprehensive manner.
