Managing iOS Devices with Apple Configurator

My traditional interpretation of Apple’s vision on how iOS devices are used is that everyone has an AppleID. That AppleID enables them to access their apps from any iOS device they own or Mac that they own. That AppleID enables them to access mail, contacts, calendars and even files through iCloud. That AppleID also allows users to remotely wipe their device through Find iPhone and track their friends iOS devices (as in social networking via breadcrumb tracking) through Find Friends. All of this “Just Works” in a consumer sense. And it even allows for a little sharing of content across devices you own. However, larger organizations need more. They need centralized management, content distribution and most other things you find that you rely on traditional desktop computers for. Over the years, Apple has added tools for centralized control of devices. This started with ActiveSync compatibility and early forms of Mobile Device Management and has grown into a pretty robust, albeit disconnected, set of tools. Of these, Apple Configurator is the latest. Apple Configurator was released about a week ago and since, I’ve been trying to figure where it fits into the solutions architecture that surrounds iOS integrations. There are a number of other tools already available that can aid in the deployment and management of iOS devices, and Configurator is a great addition. To me, there are 3 classes of management tools for iOS. These were roughly broken up into Over the Air (OTA), cradled (USB) and content management. Apple Configurator ends up fitting into all of these scenarios in some way. Let’s start by looking at the traditional uses of these three and then look at how they are impacted by Apple Configurator. Mobile Device Management Over the Air tools, such as Profile Manager, allow for Mobile Device Management (MDM) without cradling, or syncing a devices. These tools allow you to configure policies via profiles. There is also a bit of App pushing built into most MDM solutions. Apple’s Profile Manager can push applications written in-house, but no content from the App Store. 3rd party solutions, such as JAMF’s Casper Suite, Absolute Manage MDM, AirWatch and about 15 others are able to push apps from the App Store as well, leveraging the Volume Purchasing Program (VPP) to issue apps to devices. However, when an app is pushed through one of these tools, the app becomes associated with the AppleID for the user who owns the device. Note: While we use the term push, the user has to accept all App installations on the device. For large environments, MDM is a must as it allows for centralized command and control. Pushing apps is one aspect of such control. Policies enforceable through MDM include disabling cameras, configuring passcode policies on devices (not pushing passcodes), disabling YouTube, silencing Siri, unstreaming photos, disabling iCloud Backup, forcing encrypted backups, disabling location services, controlling certificates, blocking pop-ups, controlling cookies, disabling access to the iTunes and App Stores,  and controlling what kind of media can be accessed on devices. Additionally, MDM can be used to push SSIDs for wireless networks (and their passwords/802.1x configuration information), setup mail, setup Exchange ActiveSync, configure VPN connections, configure access shared calendars (iCal shared files, CalDAV and Exchange), configure access to shared contacts (LDAP, CardDAV, Exchange and Exchange Global Address Lists), deploy Web Clips and manage certificates (either with cert files or via SCEP). In short, whether you’re using the practically free Profile Manager from Apple, Mobile Iron, Casper, AirWatch, FileWave or one of the many other tools, there are a lot of things that MDM can configure on devices. Reporting can also play a major role in how MDM tools are used. iOS Apps are owned by AppleIDs, not devices. MDM does not manage AppleIDs, but you can trigger fields in MDM databases to report back unauthorized AppleIDs being used. Reporting can also identify when devices join non-approved wireless networks (which cannot be blocked through MDM), identify devices that have been jailbroken (a major security concern for many organizations) and report on device use. Because devices can fall outside of our control, MDM also plays an important role in being able to wipe and lock devices. While some of these types of features are available via Exchange, not all people use ActiveSync. Users and administrators alike can wipe, lock and de-enroll devices at will, potentially crippling what any device with an Enrollment Profile can do. There are really 3 kinds of MDM tools: those that can push apps, those that can’t and Apple’s Profile Manager. The reason I put Profile Manager into its own class, is that it can push some kinds of apps, it’s cheap ($49.99 one time as opposed to per device per month or per device per year billing) and it’s great for some things. But Profile Manager should be used in very specific environments unless the price is the only decision making factor behind a tool. In larger environments, choosing a MDM solution is one of the most important aspects of managing mobile devices and the iOS platform is no different in that manner than other mobile platforms. MDM has some limitations, though. A good MDM solution can manage the infrastructure side of device configuration. However, content requires a completely separate tool. Additonally, MDM is a completely opt-in experience. If a user wants, they can remove their device from the MDM solution at any time. Rather than a limitation, think about the opt-in experience this way: if a user removes themselves from MDM then all content that was given to them via MDM is then taken away, except that which they have moved to the local device. Therefore, if an administrator pushes an Exchange configuration then all content from that Exchange profile is forbidden fruit, removed alongside the de-enrollment. MDM also works with Lion. Policies, centralized management, etc can be integrated with Lion. You can’t do app distribution per se, but you can push out a policy to change where the dock is on the screen, add a printer to a Mac and configure a login hook through a Profile Manager-based policy. Many of the MDM providers have begun adding functionality to their tools to allow for Mac management as well as iOS and I would expect that to become the standard in years to come. iOS is a single-user device and OS X is a multi-user device, which completes that paradigm, but Apple has made it no secret that policy-based management for Mac OS X is moving to the realm MDM (even if that is enforced through a traditional lens of directory services based policy-based management). Content Management One of the unique aspects of the iOS platform is that it doesn’t have a file system that is exposed to users. There’s no /Volumes, no C: drive and no home folders. The devices don’t log into a server, because there’s no way to interpret a server connection. The file system that is exposed to iOS devices is through the lens of each application. Sandbox is a technology that limits each application’s access in terms of memory, hard drive, etc. Each application can only communicate with resources outside of itself if there is an API to do so, APIs mostly reserved for Apple (e.g. photos, contacts, etc). Therefore, when you discuss content management from the perspective of building a large iOS solution, you’re talking about apps. The apps used for content management come in a few flavors. There are those that allow you to edit content and then there are those that allow you to read content. One way to look at this is through Safari. Sharepoint, WebDAV and various document management portals allow users to access data through the Safari browser on an iOS device. Safari will let you view various file types. But to edit the data, you would need to send it to an app, or copy it to the clipboard and access it in an app. Pages is an example of an app that can browse a file tree via WebDAV and edit content. However, planning how each type of file is accessed and what type of editing can be done on each file type or what type of resources need to be accessible can be difficult (e.g. there are a number of transitions in Keynote presentations that do not work in iOS). Cradling Devices Then there’s iTunes. iTunes allows you to backup and restore devices, update devices, etc. iTunes allows you to drop content into each application. If you look into the ~/Library/Mobile Documents, you can drop content, edit default documents and other tasks that can be done through a command line, then perform a cradled sync to an app. If networking is built into an app then you don’t have to plug a device into a computer. If an app can leverage iCloud, SMB or AFP then you can access data over the air. If you are trying to replace computers with iOS devices (a la post-PC) then you would need to plan each business task that needs to be performed and make sure not only that there is an app for that (or an app you build for that) but also make sure that you can round trip data from a shared repository and back to the network storage that the data resides on. You can also access many of the benefits of MDM without having an OTA element. This can be done with iPhone Configuration Utility. iPhone Configuration Utility can configure the same policies available through Profile Manager but relies on either a cradled or email/web server/manual way of getting policies onto devices and updating. MDM automates this, but iPhone Configuration Utility is free and can be used as well. Additionally, profiles can be exported from Profile Manager and installed in the email/web server/manual way that iPhone Configuration Utility profiles are installed. This is all probably starting to seem terribly complicated. Let’s simplify it: OTA policies and custom app deployment: MDM OTA content distribution: Apps Cradled policies and custom app deployment: iPhone Configuration Utility (free) Cradled content and app distribution: iTunes (free) OTA App distribution: AppleID/iCloud Backup and restore: iCloud or iTunes Basically, there’s a few holes here. First, AppleIDs cannot be centrally managed. Second, you need to use gift cards or the Volume Purchasing Program (VPP) to distribute apps, and Third, even when you push an app to an AppleID, the app follows the AppleID to their next organization (which causes many organizations to treat apps like consumables). Fourth, synchronizing content is done primarily through iTunes, which only syncs a device at a time, making preparation of large numbers of systems terribly complicated. Apple Configurator Enter Apple Configurator, a free tool on the Mac App Store. This tool basically fixes all of the problems that we reference, but does so over USB. This means that Apple Configurator is not necessarily a replacement for MDM. In fact, you can deploy Trust and Entrollment profiles for MDM and automate the MDM enrollment for a device through Configurator. Instead, Apple Configurator is a tool that can either Prepare or Supervise an iOS deployment and do so in a manner that is easy enough that you don’t need a firm background in IT to manage devices on a day-to-day basis. Here is what Apple Configurator can do: Update iOS devices to the latest version of iOS. Rename devices using a numbered scheme (e.g. iPad 1, iPad 2, etc). Erase (wipe) iOS devices. Backup and Restore iOS devices. Deploy profiles/policies (e.g. no Siri for you, disable cameras, setup wireless, etc) to iOS devices. Export profiles. Activate devices (after all a restore of a freshly activated device is an activation). Push any kind of app to devices. Track Volume Purchase Program (VPP) codes used on devices. Revoke VPP codes used on “Supervised” devices (more on supervision later). Assign users from directory services to devices. Load non-DRM’d content to apps on devices. Can work with up to 30 devices simultaneously (think big USB hubs or carts on wheels … Continue reading Managing iOS Devices with Apple Configurator
