Enterprise Mobility Management (EMM) segments into Mobile Device Management (MDM) and Mobile Application Management (MAM). While MDM enables organizations to secure and control mobile devices, MAM facilitates application delivery and management. With the increasing adoption of BYOD, you can typically implement a MAM solution, such as XenMobile, to assist with application delivery, software licensing, configuration, and application life cycle management.
With XenMobile, you can go a step further to secure these apps by configuring specific MAM policies and VPN settings to prevent data leak and other security threats. XenMobile provides organizations with the flexibility to deploy their solution as a MAM-only or a MDM-only environment, or to implement XenMobile as a unified XenMobile Enterprise environment that provides both MDM and MAM functionality within in the same platform.
In addition to the ability to deliver apps to mobile devices, XenMobile offers app containerization through MDX technology. MDX secures apps through encryption that is separate from device level encryption; you can wipe or lock the app, and the apps are subject to granular policy-based controls. Independent software vendors (ISVs) can apply these controls using the Worx App SDK.
In a corporate environment, users use a variety of mobile apps to aid in their job role. The apps can include apps from the public app store, in-house developed apps, or native apps as well, in some cases. XenMobile categorizes these apps as follows:
Public apps: These apps include free or paid apps available in a public app store, such as iTunes or Google Play. Vendors outside of the organization often make their apps available in public app stores. This option lets their customers download the apps directly from the Internet. You may use numerous public apps in your organization depending on users’ needs. Examples of such apps include GoToMeeting, Salesforce, and EpicCare apps.
Citrix does not support downloading app binaries directly from public app stores, and then wrapping them with the MDX Toolkit for enterprise distribution. If you need to wrap third-party applications, work with your app vendor to obtain the app binaries which you can wrap using the MDX Toolkit.
- In-house apps: Many organizations have in-house developers who create apps that provide specific functionality and are independently developed and distributed within the organization. In certain cases, some organizations may also have apps that ISVs provide. You can deploy such apps as native apps or you can containerize the apps by using a MAM solution, such as XenMobile. For example, a healthcare organization may create an in-house app that allows physicians to view patient information on mobile devices. An organization can then use the MDX Toolkit to wrap the app in order to secure patient information and enable VPN access to the back-end patient database server.
- Web and SaaS apps: These apps include apps accessed from an internal network (web apps) or over a public network (SaaS). XenMobile also allows you to create custom web and SaaS apps using a list of app connectors. These app connectors can facilitate single sign-on (SSO) to existing Web apps. For details, see App connector types. For example, you can use Google Apps SAML for SSO based on Security Assertion Markup Language (SAML) to Google Apps.
- Citrix mobile productivity apps: These are Citrix-developed apps that are included with the XenMobile license. For details, see About mobile productivity apps. Citrix also offers other business-ready apps that ISVs develop by using the Worx App SDK.
- HDX apps: These are Windows-hosted apps that you publish with StoreFront. If you have a Citrix Virtual Apps and Desktops environment, you can integrate the apps with XenMobile to make the apps available to the enrolled users.
Depending of the type of mobile apps you plan to deploy and manage with XenMobile, the underlying configuration and architecture will differ. For example, if multiple groups of users with different level of permissions will consume a single app, you may have to create separate delivery groups to deploy two separate versions of the same app. In addition, you must make sure the user group membership is mutually exclusive to avoid policy mismatches on users’ devices.
You may also want to manage iOS application licensing by using the Apple Volume Purchase Program (VPP). This option will require you to register for the VPP program and configure XenMobile VPP settings in the XenMobile console to distribute the apps with the VPP licenses. A variety of such use cases makes it important to assess and plan your MAM strategy prior to implementing the XenMobile environment. You can start planning your MAM strategy by defining the following:
- Types of apps - List the different types of apps you plan to support and categorize them, such as public, native, Worx, Web, in-house, ISV apps, and so on. Also, categorize the apps for different device platforms, such as iOS and Android. This categorization will help with aligning different XenMobile settings that are required for each type of app. For example, certain apps may not qualify for wrapping, or a few apps may require the use of the Worx App SDK to enable special APIs for interaction with other apps.
- Network requirements - You need to configure apps with specific network access requirements with the appropriate settings. For example, certain apps may need access to your internal network through VPN; some apps may require Internet access to route access via the DMZ. In order to allow such apps to connect to the required network, you have to configure various settings accordingly. Defining per-app network requirements help in finalizing your architectural decisions early on, which will streamline the overall implementation process.
- Security requirements - Defining the security requirements that apply to either individual apps or all the apps is critical to ensure that you create the right configurations when you install XenMobile server. Although settings, such as the MDX policies, apply to individual apps, session and authentication settings apply across all apps, and some apps may have specific encryption, containerization, wrapping, encryption, authentication, geo fencing, passcode or data sharing requirements that you will need to outline in advance to simplify your deployment. For details on security in XenMobile, see Security and User Experience.
- Deployment requirements - You may want to use a policy-based deployment to allow only compliant users to download the published apps. For example, you may want certain apps to require that device encryption is enabled or the device is managed, or that the device meets a minimum operating system version. You may also want certain apps to be available only to corporate users. You need to outline such requirements in advance so that you can configure the appropriate deployment rules or actions.
- Licensing requirements - You should record app-related licensing requirements. These notes will help you to manage license usage effectively and to decide if you need to configure specific features in XenMobile to facilitate licensing. For example, if you deploy an iOS app, irrespective of whether it is a free or a paid app, Apple enforces licensing requirements on the app by making the users sign into their iTunes account. You can register for Apple VPP to distribute and manage these apps via XenMobile. VPP allows users to download the apps without having to sign into their iTunes account. Additionally, tools, such as Samsung SAFE and Samsung KNOX, have special licensing requirements, which you need to complete prior to deploying those features.
- Allow list and block list requirements - You likely want to prevent users from installing or using some apps. Create a block list of apps that define an out of compliance event. Then, set up policies to trigger when a device becomes non-compliant. On the other hand, an app might be acceptable for use but might fall under the block list for some reason. In that case, you can add the app to an allow list and indicate that the app is acceptable to use, but isn’t required. Also, keep in mind that the apps pre-installed on new devices can include some commonly used apps that are not part of the operating system. Those apps might conflict with your block list strategy.
