Considerations for configuring 

SafetyNet

 attestation 

The 

Google

 

SafetyNet

 attestation failure option is a compliance profile setting for 

Android

 devices and 

BlackBerry Dynamics

 apps that allows you to specify the actions that occur if devices or apps do not pass 

SafetyNet

 attestation. To set this option, navigate to 

Policies and profiles > Compliance > Android

 tab. 

If you do not enable the ‘

Google

 

SafetyNet

 attestation failure’ compliance rule, apps that are already activated will not have compliance actions enforced on them.

When you enable 

SafetyNet

, attestation during activation is performed; you cannot use a policy to enforce attestation during activation. 

The 

BlackBerry UEM Client

 is not required for you to enable 

SafetyNet

 attestation.  

The 

BlackBerry UEM Client

 does not appear in the list of 

BlackBerry Dynamics

 apps that you can configure for 

SafetyNet

 attestation. 

BlackBerry UEM

 sends attestation challenges to, and receives responses from, the 

BlackBerry UEM Client

.

BlackBerry UEM

 sends attestation challenges to each 

BlackBerry Dynamics

 app that you configure.

BlackBerry UEM

 does not trust old versions of apps. For example, if you want to enable attestation challenges for 

BlackBerry Work

, you must ensure that the version of 

BlackBerry Work

 on your organization's devices is the latest version or new activations will fail. Note that until you enable the “Google SafetyNet Attestation failure” option in your organization’s compliance profile, even if your existing activated users are using older versions of apps, no adverse action will be taken on apps or devices. 

In addition to activation and periodic attestation, 

BlackBerry UEM

 uses new REST APIs that allow you to create custom server workflows. For example, if an app needs to access a specific secure remote item, before granting access, the app server communicates with 

BlackBerry UEM

 to enforce 

SafetyNet

 attestation on the app or device. 

If a user's device is out of coverage, turned off, or has a dead battery, it cannot respond to the attestation challenges that 

BlackBerry UEM

 sends and 

BlackBerry UEM

 will consider the device to be non-compliant. If you have your organization's compliance policy set to wipe the device when it is out of compliance, if the device does not respond before the grace period expires, data on the device will be deleted when it connects to a wireless network. 

If you set a time in App grace period field, only apps that do not respond within the time frame that you set will have an action taken on them. For example, if you set the App grace period value to 7 days, and your users use 

BlackBerry Work

 every day, but do not use 

BlackBerry Tasks

 within the 7 days, only 

BlackBerry Tasks

 will have an action taken on it.

If you add a new app to 

BlackBerry UEM

 and it fails attestation during activation, the app is not activated no matter which option you have configured in the 'Google SafetyNet attestation failure' section of your organization's compliance profile. If an app has already been activated, it is subject to the rules that you specified in the compliance profile.

Your organization's users must have the latest version of 

Google Play

 services installed.

If a device fails attestation, there is no indication of the failure in the OS compromised column on the Managed devices page.
