Students and cell phones were a match made in heaven. Young people tend to be intensely social, highly inventive, and fundamentally averse to authority. With their quick-twitch muscles at peak performance levels, they can summon and send an astonishing amount of information on devices hidden in purses, pockets, backpacks, and even hats and shoes, without having to stare directly at the screen for more than a second or two at a time.

It is a model of adaptive evolution. It is also the source of increasing worry for parents, school administrators, and school IT professionals.

The problem with cell phones in schools

With unmitigated access to the internet on campus, students can (and do) cheat on exams, view and share grossly inappropriate images, and take bullying and revenge to whole new levels. Girls who have a grudge against another girl have been known to slip their phone under the wall of a bathroom stall, take pictures of the girl, and broadcast them on the web. Locker rooms are also a place where cell phone cameras can pose extreme threats to personal privacy.

What’s more, younger and younger children are being equipped with cell phones. In an April 2012 article in CNET, “One-fifth of third-graders own cell phones” we find this arresting statistic: “According to a new study, 83 percent of middle schoolers, 39 percent of fifth-graders, and 20 percent of third-graders have a mobile device.” The privacy of young children is threatened by the presence of these devices in the hands of their classmates.

Because of how easy it is to cheat via cell phones (texting test questions to people, taking photos of test pages, etc), some cities (like New York City) actually ban them in their public schools. But because of their size and portability, cell phones are all too easy to conceal and everyone acknowledges that they are still found on campuses throughout the city.

A May 2012 article in The Atlantic, “Do Cell Phones Belong in the Classroom?” highlights the use of cell phones even when they are officially banned: “An April 2010 study by the Pew Internet and American Life Project and the University of Michigan found that in schools that permitted students to have cell phones, 71 percent of students sent or received text messages on their cell phones in class. In the majority of schools — those that allow students to have phones in school but not use them in the classroom – the percentage was almost as high: 65%. Even in schools that ban cell phones entirely, the percentage was still a shocking 58%.”

So the reality is, no matter what it says in a school’s official policies, cell phones are probably here to stay in the hands of students. And as one school administrator in Ohio said, “We’re scared to death about what’s coming on campus. We know we have to control it.” That same Ohio administrator also said that they are trying to “catch up” with the technology being used to get around their rules with handheld devices while on campus. He recently purchased ZENworks Mobile Management precisely because it will help him take control of these issues.

Using ZENworks Mobile Management to control cell phones in schools

ZENworks Mobile Management is a powerful tool that can help you manage this reality. It lets IT manage an extremely diverse array of mobile devices without significantly increasing IT overhead. It installs in hours. And its automated, over-the-air enrollment makes device management an entirely hands-off process. Plus, one ZENworks Mobile Management server can run multiple back-end e-mail servers, rather than the 1:1 ratio other tools require.

Here are some of the features that make ZMM so useful in controlling cell phone usage in an academic environment. With ZENworks Mobile Management you can:

  • Define and enforce security policies
  • Disable hardware features like the camera
  • Prevent access to the internet for cell and tablet users who refuse IT oversight
  • Prevent iOS devices from backing up or restoring from iCloud
  • Grant and block rights to specific apps (like Facebook)
  • Track end-user text messaging and phone logs
  • Push specified mobile apps to the device
  • Provide secure access to read-only files and shared files
  • Push out email notifications to all users, or groups of users
  • Keep track of where students are – Location tracking allows admins to know whether or not students are on campus (for attendance/security) or to track a missing device
  • Push down WiFi configuration and any updates to the configuration will be automatically applied to the devices, e.g. change in the shared key
  • Use Apple’s Volume Purchase Program (VPP) for iOS applications

How it works

Since students and faculty use their personal devices at school, you can’t install ZENworks Mobile Management on the phones before you distribute them like you can with company-issued devices. However, for BYOD (Bring your own Device) users like students, you can still take control of what they can use on campus.

You give users the option to download the ZENworks Mobile Management app when they attempt to use their cell phone or tablet to access the school’s server and email. (Your school can set it up so that getting school-owned email is important to students, by making it the only conduit to receive announcements, class assignments, grades, and news about activities.) In order to proceed, they must accept the policies IT has defined, which means they accept the IT control those policies allow.

The ZMM app brings down policies from the server that governs the device. Connecting to the ZMM server via any Wi-Fi or cellular source allows the device to stay current with any updates to the policies. It will also allow the user to retrieve email if the ZMM server is proxying their ActiveSync email. If a user uninstalls the app or they become non-compliant, they lose connection with the ZMM server and email stops working.

If the ZMM app is on the device, the device is restricted all the time – whether the student is on campus or off, during school holidays, etc. The impetus for users to enroll with the ZMM server and keep the ZMM app on their device is connection to the server and access to email.

What you can block on student cell phones

Internet
You can block the use of the device browser and third party browsers on iOS and Windows Mobile devices. You can’t block specific sites—you either allow access to the internet, or you don’t.

Apps
If you want to block apps like Facebook, there are controls available for iOS devices (iPhone/iPod touch/iPad) in this area. Apps can be blocked by using Apple’s rating system. Applications that violate rating restrictions can be blocked from being installed. Even those installed prior to the rating restriction or those installed over iTunes will be hidden on the device. Admins can also block application installation altogether and they can block iTunes.

Camera
You can disable specific hardware features, including the camera. In addition to disallowing the camera, iOS devices can be restricted in the use of Apple’s Photo Stream. One restriction erases Photo Stream photos from the user’s device and prevents photos from the Camera Roll from being sent to Photo Stream. If there are no other copies of these photos, they would be lost. Another restriction can prevent a user from posting and sharing a Photo Stream album with other iOS users or through the iCloud Web site.

Tracking text messages and phone logs on student cell phones

If you suspect someone has been using their phone to cheat or bully, you can use the Audit Tracking Policy to investigate and prove it. (Assuming they are using a device that supports Audit Tracking.)

You can search the text message logs – they record date, subject, message body, message origination, etc. Phone logs can also be searched – they record date, call duration, call origination, to/from phone number, etc.

Of course you can’t prevent aggressive messaging – ZMM does not filter or block messages based on content. But if students know that the content of their messages is being recorded and that phone logs of their calls detail date/time, call duration, call origination, To/From phone, etc., this is a powerful deterrant. It means that you will be able to discover that they sent the bullying or cheating messages, and you can prove it to their parents, school authorities, and law enforcement agents.

Keep in mind that there might be limitations to any policy, since some device platforms might not support the functionality. For instance, iOS devices do not support text and phone log audit tracking, but IT Admins can disallow texting altogether on Windows Mobile devices. Check out the Device Functionality Comparison Table to see what kinds of policies are possible on the different device platforms.

Easy to Administer

You can remotely add new rules without touching any devices. Administrators create Policy Suites, which are collections of policies such as application control, audit tracking, file share permissions, security settings, and more. You can even set alerts to automatically bring your attention to problems, violations or changes in security settings.

Another important benefit is the ability to push files and messages to all teachers, or all students, or everyone at the same time. Email messages can be sent from the server to all users, groups of users, or to individual users. This could be used to send an email warning to all users when there is a security threat on campus.

Supports most device platforms

ZENworks Mobile Management supports most popular platforms:

  • Apple iOS 4-6 iPhone, iPod and iPad
  • Android v 2.2-4 (enhanced functionality with NitroDesk – TouchDown v7.2)
  • Windows Mobile 6.1 & 6.5

    Hi,

    Not sure if I should leave a message here regarding to the ZENworks Mobile Management.

    I’m now testing the ZENworks Mobile Management and found that it would be great if the following areas can be improved :

    1. There is no way to create groups for the mobile devices in ZENworks Mobile Management so that we cannot install Apps and apply policies based on the group level, instead, we will need to install Apps on a per device basis.

    2. There are quite a few extra steps to create an iOS Apps in “Mobile Apps”, such as manually copy the links of the iOS Apps from the Apps Store, manually downloading the icon for the Apps, etc. I have seen another product which can actually search the name of a particular Apps from within the mobile device management system and then all the necessary information of the Apps such as URL and icon will be downloaded automatically for the mass distribution.

    3. I found that there are no easy way to distribute a .IPA Apps file which has been downloaded via iTunes Store, in order to bypass the inputting of the Apple ID. If this can be done, it will really help to push the iOS Apps to the iOS devices, in which downloading the iOS Apps are always request the input of the Apple ID (I have seen another product which can easily download the iOS Apps from iTunes Store and then distribute this downloaded Apps (e.g. .IPA) to the mobile devices without requesting the input of the Apple ID.

    4. Lastly, I found that it will take a long time for the “Managed Apps” and “Installed Apps” information of each mobile device to reflect the changes, for example, if I have finished installing an iOS Apps from the “Managed Apps”, it will take quite a long time to reflect this change and thus some options such as reinstall Apps or uninstall Apps will not be able to available during that time.

    My name is Alvin and I’m from the ICT Operations Department in Chinese International School.
    My contact is : achung@cis.edu.hk & (852) 2512 5951

    P.S. I was a ZENworks user and administrator when we were using Windows and now we have changed to a school with a lot of the MacBook Pro and iOS devices, so I want to see if ZENworks Mobile Management solution can satisfy our needs.

    Best Regards,
    Alvin

      Alvin,

      I agree with everything you’ve said. Here are a few short replies to your questions above.

      1. Group management via LDAP will be available in our 2.7 release in Q1 2013 shortly after our Brainshare convention. Restricting application installation, however, is a deeper issue especially for iOS as you cannot do so currently. We can have someone reach out to you for questions and demo, though.

      2. We are looking into these exact enhancements. Definitely in our future ZENworks console integrated ZMM solution this will be available. We are researching the efforts in the current ZMM solution as well. I know it is a bit of extra work to copy paste the URL and icons, so we want to address that.

      3. If I understand correctly, you want to purchase an Apple App Store app, then distribute the .ipa? If this is the case, sadly Apple will not allow that. Strictly against Apple’s entire being. You can only distribute in-house or B2B applications.

      4. Managed app installs and updates depend on user action as well as the Apple APN service, which is not guaranteed by Apple. It could take anywhere from 5 seconds to a few hours, if at all. It is all a push notification service Apple provides.

      Someone should be in touch shortly.

      Regards,
      Bryce Romney
