How can the IT department assure that the enterprise sees the benefits of BYOD  instead of unmanageable mobility that creates chaos for the existing IT environment?
“You have to address what end users want in terms of personal choice — but don’t start there,” says Jack E. Gold, president and principal analyst with the consulting firm J.Gold Associates. “Think about what your business needs first, then retrofit the technology that works the best to achieve those goals.”
That means seeing BYOD not as an end game. It’s one component in a robust mobile strategy that addresses all the areas in which mobility makes sense and creates a long-term roadmap for delivering the appropriate applications and services.
“You don’t want to do BYOD with a series of short-sighted projects,” Mark Jordan, senior product manager for mobility at Sybase, advises.
Enterprises also should update their existing mobility policies, which may have been tucked away in three-ring binders or file cabinets since their initial creation a decade ago. “Organizations really need to re-evaluate all these policies in light of the latest technologies and the most recent regulatory issues for information management that apply to their industries,” recommends Sean Ginevan, product manager for MobileIron, which supplies a mobile-device management (MDM) solution to the company.
For security and management ease, BYOD rules should address five core considerations:
Answering the last question will be complicated because security and management capabilities of some hardware and OS combinations are still a work in progress, experts say. For example, some Android smartphone manufacturers, including Samsung, Motorola and LG, are customizing the Android OS with proprietary management capabilities , such as enhanced password controls, hardware-based encryption and hardened e-mail security.
These extensions are a security plus for IT managers, but the lack of standardization means the enterprise will need to develop alternative management policies for other Android smartphones that run more basic versions of the OS. But what kind of alternative policies?
IT, for example, may decide to force users of the basic OS to access corporate e-mail through a security application. By contrast, the IT department may decide it is safe for devices with proprietary security extensions to connect directly to the corporate e-mail server. Or it may decide that some systems or data are off-limits to all BYOD devices.
For added security , and an absolute necessity for organizations in highly regulated markets, IT shops may want to issue an authentication certificate for each BYOD device. A step up from password security, the certificates confirm that both the users and their individual hardware have been authorized to access the network.
Fortunately, a variety of tools are available to help IT administrators implement and enforce the BYOD policies they create. Mobile-device management software can act as a kind of command center, letting IT managers centrally configure access authorizations and business applications.
MDM solutions also let the IT department track devices, confirm device security settings, and create virtual private networks (VPNs) that establish protected communications links between users in the field and the enterprise network. An MDM application can also check that each device is running an updated version of its OS and scan for malware before a user device connects to the corporate network. If the hardware is lost or stolen, IT administrators can go to the MDM command center to wipe the data.
“MDM can push down a variety of settings to individual devices, but just as importantly, it enables IT managers to take all those settings back,” Ginevan says. “So when someone leaves the enterprise, I can delete all the corporate e-mails, corporate applications and any security certificates that identify the device to the network.”
Because MDM tools can streamline or automate so many basic device-management tasks, IT isn’t scrambling to service hundreds or perhaps thousands of individual devices. “That gives IT administrators more time to focus on strategic tasks, such as building and mobilizing applications inside their enterprises,” he says.
Another important mobile management technology is desktop virtualization, which lets IT create individualized desktop environments tailored to each notebook, smartphone or tablet. With virtualization, staff members use their mobile devices to send screen images and keyboard clicks over wireless networks to applications centrally stored in the back-end data center, which also houses all corporate information. Because data doesn’t reside on mobile devices, there’s less risk of a security breach if portable hardware is hacked or stolen.
For its BYOD strategy, Citrix Systems enhances each device with its own commercial technology, Citrix Receiver. It connects end-user hardware to virtual desktops created by central IT administrators. To protect the messages flowing back and forth between users and data center systems, Citrix establishes VPNs that support data encryption.
Michael McKiernan, vice president of business technology at Citrix, says members of the Citrix staff that are part of the BYOD program accept client virtualization in part because data and applications stored in a central location make those resources accessible from any one of the multiple computing devices they may own.
“If the data is stored on a C drive in one computer, they may not always have access to it,” he says.
And what about the potential for greater security risks if IT doesn’t have complete control over the devices that each person uses? “The rubber hits the road with our results after three years. We have not seen our exposure increase,” he says. “If you provide the right incentives for people to protect corporate data, they will. Just because someone chooses to use their own MacBook, they don’t suddenly turn into a deviant.”
