About J-Virtual Mobile Platform
J-Virtual Mobile Platform (J-VMP) is a Virtual Mobile Infrastructure (VMI) solution that hosts independent workspaces for all users. The mobile user virtual workspace is based on the Android operating system and can be accessed via the J-VMP mobile client application installed on Android or iOS devices.
The J-VMP application allows users to access the same mobile environment, including all applications and data used at work from anywhere without being limited to a single mobile device. Users get full access to Android features and controls for an authentic Android user experience.
All mobile workspaces are hosted on the server and managed by administrators, ensuring clear separation between personal and corporate data for better data management and security within the enterprise.

 Common Criteria Evaluation

The functionality described in this guidance documentation is limited to the security functionality described in the Security Target.
Other product functionality is not applicable to the claimed Protection Profile and was therefore not examined as part of the Common Criteria evaluation of the J-VMP product.
The evaluated configuration also includes several assumptions and requirements that must be met by the intended environment in order for the installed J-VMP Client to be in the evaluated configuration.

These are as follows

• The J-VMP Server relies upon a trustworthy computing platform for its execution.
• The administrator of the application software should administer the software within compliance of the applied enterprise security policy.
• The Security Target is the J-Virtual Mobile Platform (J-VMP), Version 6.1.0.
  The J-Virtual Mobile Platform (J-VMP) 6.1.0 was tested on the following mobile devices.

Guidance

Updates and Update Verification

Users obtain J-VMP Client updates using Android or iOS update mechanisms or from J-VMP server.
If the application is installed using the Apple App Store or the Google Play Store, it may be updated automatically if your App Store or Play Store is configured to do so. If it is not, selecting the “update” option for the application in the Store application will verify that the application package is valid and install it over the older version.
If users are using an enterprise version client, they will install and upgrade the application form J-VMP server. J-VMP server can set the current version and min version supported. in this case the administrator need to follow Apple’s guidance for enterprise installations and Google’s guidance for installing an application from “unknown sources”. iOS and Android will only replace the existing application with the updated one if the signing keys are the same and that the new applications are signed properly and have not been tampered with.
