Mobile Device Management – Containing The Mobile Invasion

April 11, 2013 By Jason Palmer Leave a Comment

Mobile Devices

Mobile Devices

When Dorothy in the “Wizard of Oz” was walking through the Forrest, she exclaimed, “Lions and Tigers and Bears – Oh my.”    Trust me when I say that most Information Technology Staff have the very same sentiment, “Cell Phones, Tablets, and Notebooks – Oh My” when walking through the office and seeing the extreme variety, feel every bit as much in peril as Dorothy.

Why?  Because every one of those devices is a potentially unsecured entry point in to the corporate network and might be able to access sensitive data.

What is an Information Technology Manager to do?   Ban all mobile devices from accessing the Network?  Demand that only mobile devices issued by the Company and properly secured may connect to the Network?  Tell the CEO that she cannot use her iPad to read her mail?  Tell the CFO that he cannot access or look at the latest corporate financials on his iPhone because Apple does not understand “enterprise security?”  Make everyone use a Blackberry curve?

There must be a better answer and there is.

It is called Mobile Device Management.  The technology is available from a number of different vendors.  It enables Information Technology Staff to secure and manage most well know brands of Smart Cell Phones, Tablets, and Notebooks from a centralized console.

Each Mobile Device Management vendor implements the solution slightly differently but with the same general result:  the Information Technology Staff can apply and enforce usage policies, approve specific apps, determine the location of the device, enforce proper login credentials, and remotely wipe lost or stolen devices.

Another great feature is the standardization of Management Interface (Dashboard) of the various mobile platforms.  The Information Technology person does not need to be concerned about if he or she is managing an iPhone or an Android phone.  The Mobile Device Management software presents a single, unified view by class of device:  All Cell Phones and All Tablets.  Of course the granularity is there should one want to take advantage of specific features available in say an IOS device (iPhone, iPod, iPad) vs. and Android phone or tablet.

When performing a review of Mobile Device Management software platforms, there are a number of considerations to review.  These include how many devices you have to manage?  Are they predominantly Apple devices, Android Devices or something else?  Are the mobile devices being used in your corporate environment by your employees supported?  Does the Mobile Device Management Platform support all the versions of the mobile device operating systems in-use?  And, from an Administrative perspective:  Is the software license purchased as a one-time fee or is this a monthly service?

The important take-away from this article is that mobile devices, especially ones that your own Information Technology Department do not official support represent a real threat to your sensitive corporate data and need to be “cleared” prior to being allowed to access data on your network.

Think of it this way:  For those of you that work in larger offices, visitors are signed in, logged, and guided.  They don’t just wander in the front door and walk aimlessly around office.

Why would you allow a perfect stranger, such as someone’s personal smart phone, access your corporate data network without being escorted in?

The answer:  You wouldn’t

Hurricane Tech – Make your Smartphone a WiFi Hot Spot with Tethering

January 1, 2013 By Jason Palmer Leave a Comment

WiFi TetherWhen the Power is out, if you do not have a Generator, access to the Internet through your home or office Wired or WiFi Router will be out as well.  Fortunately, Smartphones and many WiFi capable devices such as iPad’s, eReader’s, and Notebook Computers can run on Battery Power when Electrical Power is not available.

A technology called “Tethering” allows many Smartphones to share their Internet data connection capability through the embedded WiFi in the Smartphone.  This enables the Smartphone to become a mobile Hot Spot, similar to a MiFi so that any other WiFi enabled device, like your WiFi only iPad, eReader, or Notebook Computer can access the Internet through your Smartphone.

(For more details on mobile data Internet connections, see my article “Mobile Communications Technology Overview”.)

In many cases the Cellular Carriers such as Verizon, AT&T, and Sprint charge an extra monthly fee for the Tethering capability and a separate Data Plan for the additional usage.  This is especially true if your phone has a grandfathered “Unlimited Data Plan.”  Verizon requires Unlimited Data Plan users to have a separate data plan for Tethering.  With the new Verizon Share Everything Plans, the Data usage and Tethering capability are included and you only pay for the Data you use across all of the devices on your Share Everything Plan.  With other Carriers you may still be required to pay an extra fee for the Tethering capability of your Smartphone.

However, every rule has its’ exceptions.  With certain Smartphones based on the Android mobile operating system, (that would be most phones that are NOT iPhones, Windows based, or Blackberry’s), “unofficially” no additional fee is required.  At Verizon, it is official, based on the FCC Tethering consent decree in July 2012. You need only to browse the Google Play Store, searching on the word, “Tethering” to download an “App” that can turn the Tethering Feature “On” for you.

To clarify:  If you have either a 3G or 4G Tiered Data (like the Verizon Share Everything Plan or AT&T Mobile Share Plan), you can download any number of 3rd Party Apps which will enable your Android to Tether and become Mobile Hot Spot.  Unlimited Data Plan Users technically still need to pay Verizon or AT&T a Tethering Fee and have a separate data plan.  You should call your Cellular Carrier to verify the usage terms of your Agreement.

Be advised that right now some of the Carriers seem to be ignoring this grey area of the usage policy but that is subject to change. Keep in mind that the Carrier will absolutely know if you are sharing your Smartphone Data capability using Tethering – so you have been warned.  It is possible that you could get a call or letter from your mobile phone Carrier stating that you need to pay an additional fee or purchase an additional data plan.

A Special Note for iPhone Users:  If your iPhone supports Tethering, (IOS 4 or later), you may need to use either the USB Charging Cable or pair the Notebook Computer with your iPhone via Bluetooth to use the Internet capability of your phone with your Notebook Computer.  If you have an iPhone5, then you can definitely Tether via WiFi as described above. IOS 6 has a built-in App for turning the iPhone5 in to a Mobile Hot Spot. (Apple prefers to call it a “Personal Hot Spot.”)  If you use the native Apple IOS 6 App, you will definitely need either one of the NEW Mobile Share Plans from AT&T or the one of the NEW Share Everything Plans from Verizon or similar plan from your Carrier.

Android 4.0 coming to Galaxy Tab

June 20, 2012 By Jason Palmer Leave a Comment

Samsung Galaxy Tab 7.7A list was leaked by Samsung that shows that almost every model of the Samsung Galaxy Tab from the Tab 7 series to the Tab 10.1 is due to get the latest Android 4.0 release known as Ice Cream Sandwich (ICS).

Availability and deployment of the update is tentatively to start in July 2012 with most updates appearing in August.

Unfortunately, the original Galaxy Tab will not be getting the upgrade as the hardware is not capable of truly supporting the upgrade.  (There will certainly be unsupported hacks to force ICS on to an original Galaxy Tab and if you understand what that means, no explanation is necessary.)

WiFi only tablets will get the Android 4.0 Ice Cream Sandwich upgrade first as Samsung has complete control over WiFi units.  Samsung must work with the Cellular Data Carrier Providers to test the software update on the Carriers network prior to update and deployment.

The list of Samsung Galaxy Tab Models slated to get the update are:

GT-P6210 Galaxy Tab Plus 7.0
WIFI
GT-P6200 Galaxy Tab Plus 7.0
WIFI + 3G
GT-P6810 Galaxy Tab 7.7
WIFI
GT-P6800 Galaxy Tab 7.7
WIFI + 3G
GT-P7310 Galaxy Tab 8.9
WIFI
GT-P7300 Galaxy Tab 8.9
WIFI + 3G
GT-P7510 Galaxy Tab 10.1
WIFI
GT-P7500 Galaxy Tab 10.1 WIFI + 3G

Free Video Calling Applications

June 16, 2012 By Jason Palmer Leave a Comment

FaceTime Dual Phone Video ChatThe most well known free video calling applications are probably Apple FaceTime for the iPhone, iPad, iTouch, and Skype for almost every other platform such as Windows, Android, IOS (iPhone, iPad, iTouch), and Mac. Although FaceTime and Skype probably have the most number of registered users and best marketing, other lesser known free video calling applications have more features that are truly free and do not require the purchase of premium subscription plans or the purchase of the application itself.

Video Chat Conference Call - 4 PeopleFor example, the ability to have a free video conference call with multiple people requires a premium paid subscription with Skype.  And, if you want to use Apple FaceTime on a Mac, the application has to be purchased from the Mac App Store.  In ooVoo, a much lesser known free video and audio calling application, between six and twelve simultaneous can participate depending on the platforms of each caller – Windows, Android, IOS, or Mac.

Other free video calling applications like Fring and Movicha (Mobile Video Chat) will support chat over both 3G/4G connections unlike FaceTime which will only work when connected via WiFi.  [ Apple has recently announced that with the release of Apple IOS 6, the newest iteration of the operating system for the iPhone, iPad, and iTouch that FaceTime will also support connections over 3G/4G. ]

AIM, Windows Messenger, Yahoo Messenger, Google Talk LogosNot to be left out, the major text chat messenger products, such as AIM (AOL Instant Messenger), Yahoo Messenger, Microsoft Messenger (Part of Windows Live Essentials), and Google Chat all now include the ability to make free video calls.

Unlike the Telephone System, there is no one standard way in which any of these free video calling applications communicate.  Each application can only communicate with other users who are running the same application.  Skype can only call other Skype(*) users and FaceTime can only call other FaceTime users.   The feature set and capabilities vary as to their popularity and penetration in to the marketplace so you will probably have to install more than one free video calling application to connect with your specific contacts.

Skype Logo*Skype is a Voice Over IP (VoIP) phone service that uses the Internet to complete calls between multiple Skype Application users or between a Skype user and a traditional land line or cell phone user.  Skype to Skype calls are free.  Skype calls to land lines and cell phones, both domestically and internationally, are charged at very low rates that are significantly less expensive than traditional land line and cell phone carriers.  Skype allows for instant messaging and chat when voice and/or video calls are not supported.  Skype usage is partially restricted by some Cellular Carriers to work only when a WiFi connection is available or only for International connections as the Cellular Carriers want you to use your phone plan voice minutes instead of free calling applications that would potentially travel over the 3G/4G data plan on the phone.

Other Instant Messenger products listed below have or are adding the ability to call out to traditional land line and cell phones as well.
