Versatile mobile devices are becoming more business friendly, but IT needs help managing them
|
Executive Summary: As smartphones make life easier for mobile business users, they’re also adding management and security challenges to IT’s plate. Mobile device–management and security tools can help IT take control of these challenges. |
today’s smartphones—multifunction mobile phones that run some type of mobile OS—are crammed with capabilities that are making them must-have business devices. Research firm In-Stat predicts that smartphone adoption rates will grow more than 30 percent over the next five years, with that growth largely occurring at the expense of traditional mobile phones. Although that dramatic growth means that more employees will have access to smartphones, it also adds another item to IT’s already overcrowded tech support docket. (For a look at how smartphones have evolved into enterprise-class mobile devices, see the Web-exclusive sidebar “Smartphones in the Enterprise,”, InstantDoc ID 98898.) Smartphones present some unique challenges for IT administrators who have to choose, deploy, and manage them. Let’s look more closely at the deployment challenges smartphones pose in regard to security, systems management, and overall corporate policy.
Unique Security Challenges
Smartphones are more powerful than ever
before, but all that capability also opens the
door to a host of new security issues. Depending
on your environment, you might need
to protect smartphones from viruses and
malware or employ encryption to ensure that
sensitive corporate data isn’t stolen when
phones are lost or misplaced. According to
Michael Argast, a security analyst with mobile
security software vendor Sophos, your mobile
security priorities might differ from those for
your desktop environment. “Malware \[for
smartphones\] isn’t a huge issue at this point,” says Argast. “Defending against malware is
still important, but maintaining data confidentiality
and integrity, using encryption,
and having remote wipe options are just as
important from an overall security perspective.
The risk of malware on mobile phones
just isn’t as high as some vendors would lead
you to believe.”
As mobile devices begin to make more inroads into the enterprise, mobile security is rapidly becoming a top concern for IT pros. Here’s a sampling of products that can help you get a handle on your mobile security environment:
• Trend Micro Mobile Security 5.0 (www.trendmicro.com)—provides data encryption
and authentication capabilities to
devices in your mobile network. Data on
lost or stolen devices is password encrypted,
and anti-malware features protect your
mobile devices from test-message spam,
viruses, worms, and other security threats.
• Symantec Mobile Security Suite 5.1 (www.symantec.com)—protects mobile devices
from snoopware, malware, viruses, and
other hostile software threats by removing
Short Message Service (SMS) spam,
encrypting/decrypting device data, and
logging device access in real time. The
product encrypts and decrypts data on
mobile devices and creates logs detailing
device access.
• McAfee Mobile Security for Enterprise
(www.mcafee.com)—protects mobile
devices from viruses, malware, Trojan
horses, worms, and other malicious applications.
The product also monitors email,
Internet downloads, Wi-Fi, Bluetooth
transfers, and other transmission methods
for network threats.
• Sophos Mobile Security (www.sophos.com)—detects and deletes spyware and
viruses and also screens Multimedia Messaging
Service (MMS), SMS, email, IM
attachments, Wi-Fi, Internet downloads,
and Bluetooth transmissions for hostile
applications.
Smartphone Management
As more people use smartphones in a corporate
setting, the task of managing the
proliferation of mobile devices can quickly
become a significant challenge for IT. A
number of products and resources are available
to help IT pros with mobile device
management. Products such as Microsoft System Center Mobile Device Manager 2008
(System Center MDM) provide extensive
control options via a central console and
streamline device patching, mobile device
security, and integration of those devices
with an existing infrastructure.
For small business owners, though, a comprehensive (and prohibitively expensive) mobile device–management solution like System Center MDM might be overkill. For those customers, some vendors have stepped in to provide hosted solutions— particularly for Microsoft Exchange—that streamline management of smartphones in your environment. “Our focus is entirely on mobility,” says Patrick Gilbert, CEO and founder of 4smartphone.net, a provider of hosted email services for mobile device users. “We provide support, \[mobile device\] email configuration, hosted Exchange, and over-the-air backup of mobile phones.”
System Center MDM and Windows Mobile 6.1. Microsoft intended System Center MDM to complement Windows Mobile 6.1 as part of the company’s quest to strengthen its enterprise mobile product offerings. Each product takes advantage of features found in the other, and together they offer IT pros a compelling reason to use them both.
Windows Mobile 6.1 offers a modest number of improvements over 6.0: The main interface has been tweaked and improved, a new Getting Started center streamlines phone setup, and integration with System Center MDM helps provide better security administration—including the ability to access data via mobile device from behind a network firewall. Version 6.1 also supports the new advanced mobile policies introduced in Exchange Server 2007 SP1.
System Center MDM is Microsoft’s latest addition to its System Center product group, and it provides a number of mobile device– management features. Mobile device security has been improved, and a wireless policy enforcement feature lets administrators monitor, change, and enforce mobile group policies remotely. The ability to domain-join Windows Mobile devices and apply group policies to them is also an important feature. Microsoft says that System Center MDM streamlines the management of mobile devices, by providing the ability to scale from small installations with a few dozen devices to large enterprises with thousands of smartphones to manage.
Although System Center MDM and Windows Mobile 6.1 improve support for wireless devices in the enterprise, Microsoft isn’t about to rest on its laurels. Redmond has made little attempt to hide the fact that Windows Mobile 7.0 should hit the market in late 2008 or early 2009.
Smartphone solutions. 4smartphone .net’s Gilbert credits Apple’s iPhone for generating additional interest in the smartphone market and sees the device as a catalyst for increasing sales of competitive and complementary products. “With companies like Apple and Microsoft now putting lots of marketing dollars into promoting their mobile efforts, we’re starting to see more people get interested in smartphone solutions,” says Gilbert. “The iPhone may have dragged customers into the store, but they might have purchased a lowercost alternative.” (See the sidebar “The iPhone and the Enterprise” to learn how Apple is making the iPhone friendlier for business use.)
Here’s a sampling of mobile device– management products (excluding System Center MDM) covering the spectrum of product types:
• Azaleos OneServer with MobileXChange
(www.azaleos.com)—lets administrators
manage and provision mobile devices,
including the Research In Motion (RIM)
BlackBerry, Windows Mobile phones,
and the iPhone.
• Zenprise for BlackBerry (www.zenprise.com)—troubleshoots your BlackBerry
mobile infrastructure and identifies and
resolves problems with both Exchange
and your BlackBerry network.
• 4smartphone.net (4smartphone.net)—
provides hosted Exchange email services,
mobile device configuration, and technical
support for mobile devices.
• Check Point Software Technologies’
Pointsec Mobile (www.checkpoint.com)—secures data stored on mobile
devices running Windows Mobile,
Palm, and Symbian OSes. This product
also encrypts memory card data
transparently, minimizing the impact
of mobile security policies on end
users.
Corporate Policy
It isn’t enough to provide endpoint security
for mobile devices that access your network,
or keep a handle on mobile device deployment
and management. Equally important
is establishing sound corporate IT policies
that govern how those mobile devices are
deployed and managed.
“It’s very important for mobile devices to be managed with a consistent set of company policies and standards,” says Sophos’s Argast. “People can start plugging these devices into the network, but the admin then has no control. Can devices be secured? Do users know the proper steps to take when they lose a device?” Argast says that you can answer these questions by setting up consistent usage policies. Doing so can also ensure that the mobile device strategy at larger enterprises is compatible with current auditing and compliance regulations.
It’s clear that smartphones are becoming a more integral part of most enterprises. Today’s technology workers are more tech-savvy than ever, and having access to enabling technologies such as Ford Motor Company’s Sync and feature-laden mobile devices can make organizations even more nimble and efficient. (For more information about Sync, see the sidebar “Ford Sync Makes Mobile Phones More Mobile,” page 65.) The influx of smartphones also creates a host of challenges for any IT pro seeking to manage that rapidly growing portion of the enterprise. But armed with the right information and tools, you can make sure that the true potential of a highly mobile workforce is realized.
