3.9. Device Administration

Android includes features that allow security-aware applications to perform device administration functions at the system level, such as enforcing password policies or performing remote wipe, through the Android Device Administration API.

If device implementations implement the full range of device administration policies defined in the Android SDK documentation, they:

• [C-1-1] MUST declare android.software.device_admin.
• [C-1-2] MUST support device owner provisioning as described in section 3.9.1 and section 3.9.1.1.

3.9.1 Device Provisioning

3.9.1.1 Device owner provisioning

If device implementations declare android.software.device_admin, they:

• [C-1-1] MUST support enrolling a Device Policy Client (DPC) as a Device Owner app as described below:
  • When the device implementation has no user data is configured yet, it:
    • [C-1-3] MUST report true for DevicePolicyManager.isProvisioningAllowed(ACTION_PROVISION_MANAGED_DEVICE).
    • [C-1-4] MUST enroll the DPC application as the Device Owner app in response to the intent action android.app.action.PROVISION_MANAGED_DEVICE.
    • [C-1-5] MUST enroll the DPC application as the Device Owner app if the device declares Near-Field Communications (NFC) support via the feature flag android.hardware.nfc and receives an NFC message containing a record with MIME type MIME_TYPE_PROVISIONING_NFC.
  • When the device implementation has user data, it:
    • [C-1-6] MUST report false for the DevicePolicyManager.isProvisioningAllowed(ACTION_PROVISION_MANAGED_DEVICE).
    • [C-1-7] MUST not enroll any DPC application as the Device Owner App any more.
• [C-1-2] MUST require some affirmative action before or during the provisioning process to consent to the app being set as Device Owner. Consent can be via user action or by some programmatic means but appropriate disclosure notice (as referenced in AOSP) MUST be shown before device owner provisioning is initiated. Also, the programmatic device owner consent mechanism used (by enterprises) for device owner provisioning MUST NOT interfere with the Out-Of-Box Experience for non-enterprise use.
• [C-1-3] MUST NOT hard code the consent or prevent the use of other device owner apps.

If device implementations declare android.software.device_admin, but also include a proprietary Device Owner management solution and provide a mechanism to promote an application configured in their solution as a "Device Owner equivalent" to the standard "Device Owner" as recognized by the standard Android DevicePolicyManager APIs, they:

• [C-2-1] MUST have a process in place to verify that the specific app being promoted belongs to a legitimate enterprise device management solution and it has been already configured in the proprietary solution to have the rights equivalent as a "Device Owner".
• [C-2-2] MUST show the same AOSP Device Owner consent disclosure as the flow initiated by android.app.action.PROVISION_MANAGED_DEVICE prior to enrolling the DPC application as "Device Owner".
• MAY have user data on the device prior to enrolling the DPC application as "Device Owner".

3.9.1.2 Managed profile provisioning

If device implementations declare android.software.managed_users, they:

• [C-1-1] MUST implement the APIs allowing a Device Policy Controller (DPC) application to become the owner of a new Managed Profile.

• [C-1-2] The managed profile provisioning process (the flow initiated by android.app.action.PROVISION_MANAGED_PROFILE) users experience MUST align with the AOSP implementation.

• [C-1-3] MUST provide the following user affordances within the Settings to indicate to the user when a particular system function has been disabled by the Device Policy Controller (DPC):

  • A consistent icon or other user affordance (for example the upstream AOSP info icon) to represent when a particular setting is restricted by a Device Admin.
  • A short explanation message, as provided by the Device Admin via the [setShortSupportMessage]( https://developer.android.com/reference/android/app/admin/DevicePolicyManager.html#setShortSupportMessage%28android.content.ComponentName, java.lang.CharSequence%29).
  • The DPC application’s icon.

3.9.2 Managed Profile Support

If device implementations declare android.software.managed_users, they:

• [C-1-1] MUST support managed profiles via the android.app.admin.DevicePolicyManager APIs.
• [C-1-2] MUST allow one and only one managed profile to be created.
• [C-1-3] MUST use an icon badge (similar to the AOSP upstream work badge) to represent the managed applications and widgets and other badged UI elements like Recents & Notifications.
• [C-1-4] MUST display a notification icon (similar to the AOSP upstream work badge) to indicate when user is within a managed profile application.
• [C-1-5] MUST display a toast indicating that the user is in the managed profile if and when the device wakes up (ACTION_USER_PRESENT) and the foreground application is within the managed profile.
• [C-1-6] Where a managed profile exists, MUST show a visual affordance in the Intent 'Chooser' to allow the user to forward the intent from the managed profile to the primary user or vice versa, if enabled by the Device Policy Controller.
• [C-1-7] Where a managed profile exists, MUST expose the following user affordances for both the primary user and the managed profile:
  • Separate accounting for battery, location, mobile data and storage usage for the primary user and managed profile.
  • Independent management of VPN Applications installed within the primary user or managed profile.
  • Independent management of applications installed within the primary user or managed profile.
  • Independent management of accounts within the primary user or managed profile.
• [C-1-8] MUST ensure the preinstalled dialer, contacts and messaging applications can search for and look up caller information from the managed profile (if one exists) alongside those from the primary profile, if the Device Policy Controller permits it.
• [C-1-9] MUST ensure that it satisfies all the security requirements applicable for a device with multiple users enabled (see section 9.5), even though the managed profile is not counted as another user in addition to the primary user.

If device implementations declare android.software.managed_users and android.software.secure_lock_screen, they:

• [C-2-1] MUST support the ability to specify a separate lock screen meeting the following requirements to grant access to apps running in a managed profile only.
  • Device implementations MUST honor the DevicePolicyManager.ACTION_SET_NEW_PASSWORD intent and show an interface to configure a separate lock screen credential for the managed profile.
  • The lock screen credentials of the managed profile MUST use the same credential storage and management mechanisms as the parent profile, as documented on the Android Open Source Project Site.
  • The DPC password policies MUST apply to only the managed profile's lock screen credentials unless called upon the DevicePolicyManager instance returned by getParentProfileInstance.
• When contacts from the managed profile are displayed in the preinstalled call log, in-call UI, in-progress and missed-call notifications, contacts and messaging apps they SHOULD be badged with the same badge used to indicate managed profile applications.

3.9.3 Managed User Support

If device implementations declare android.software.managed_users, they:

• [C-1-1] MUST provide a user affordance to logout from the current user and switch back to the primary user in multiple-user session when isLogoutEnabled returns true. The user affordance MUST be accessible from the lockscreen without unlocking the device.
