2 In a recent study sponsored by Dell, 75 percent of companies surveyed had, or were considering, personallyowned devices in their environment. Executive summary Why can t I use my ipad or Android Smartphone at the office? How can we control the costs associated with mobile devices and the related voice and data plans? Do these questions sound familiar? Is your organization considering allowing personally-owned smartphones and tablets to access corporate applications and data? In a recent study sponsored by Dell, 75 percent of companies surveyed had, or were considering, personally-owned devices in their environment. The explosive growth in personal smartphones and tablets has created a strong demand to use personal devices at work. IT management must consider the needs and goals of the business, and carefully weigh the costs and benefits of allowing personally-owned devices as part of an overall mobility strategy. With the consumerization of the mobile device market, the historical approach of providing employees with locked down devices with a two-year refresh cycle may not be the best solution for organizations and their employees. Many organizations are debating the costs and benefits of allowing employees to use personallyowned devices for business needs. While reduced costs and increased employee morale are popular arguments, organizations must consider hidden costs and corporate governance issues. These concerns must be balanced with opportunities for enhanced productivity and improved employee morale when employees select a mobile device of their own preference. Introduction The desktop Internet ramp was just a warm-up act for what we are seeing happen on the mobile Internet. The pace of mobile innovation is unprecedented, I think, in world history. Consumer companies are taking the lead over enterprise companies. It is more important than ever to listen to employees about where to take your IT department. Mary Meeker, Morgan Stanley April 2010 Since the introduction of the iphone in 2007 and subsequently, the ipad and Android-based phones and tablets, the cost for mobile devices has decreased, and most are now purchased by individuals for personal use. The computing power available in these devices has also increased, rivaling the capabilities of traditional PCs from only a few years ago. Most mobile devices now support , multimedia messaging, Internet browsing, and data storage. They have become true computing devices, although still used primarily for content storage and consumption. With app stores in abundance, a variety of consumer- and enterprisefocused applications are available for download. These applications receive very little review for malicious content exposing sensitive corporate information to be copied and stored on servers outside of the organization s control. Enterprise mobility costs are increasing due to the rapid expansion in the number of devices and the resulting voice and data plans. This increase in cost, along with the consumerization of smart mobile devices, is leading organizations to consider a move from the traditional corporate-liable to a personal-liable approach to mobility. We will review the benefits and costs of both strategies and will conclude with some additional topics for consideration as your organization develops its overall enterprise mobility strategy. Corporate-liable approach to mobility devices The traditional, corporate-liable strategy has many advantages, including governance and control of the devices, as well as the potential for an overall reduction in cost to employees and the organization for mobility-related expenses. However, a well-designed corporate-liable program does not preclude access to a variety of mobile platforms that can meet the needs and preferences of employees. 2

3 Benefits of a corporate-liable approach The ability to maintain governance and control over corporate information is one of the most compelling cases for corporate ownership of mobile devices. This ensures that the organization can deploy and enforce key security policies on devices to meet compliance with regulatory or corporate governance requirements. The restriction of access to corporate data and applications through corporate-owned devices will prompt employees to report the loss or theft of a device for timely deletion of all data. The organization can also restrict content on the devices, including third-party applications, to reduce exposure to applications or content that is malicious or contrary to the organization s policies. Finally, by establishing a corporate mobile device catalog, the organization retains control over the device types and operating system versions in use to manage vulnerabilities intrinsic in some mobile platforms. This allows the organization to enforce the deployment of critical operating system and application updates to correct newly-identified vulnerabilities. While cost-reduction is frequently cited as one reason to move to a personal-liability model for mobility, there may be other opportunities to reduce mobility costs. Bulk device purchases, aggressive negotiation with carriers, and mobile expense management solutions can save money. Support and application development costs may be cut by implementing a standardized catalog of devices for employees to choose. Costs of a corporate-liable approach This corporate control comes, literally, at a cost as the organization bears the expenses for devices as well as voice and data plans. The corporation also assumes the asset management costs for mobility devices, including procurement, support, and disposal. Finally, there is the voice and data cost associated with employees personal use of employer-provided mobile devices. In addition to the expense associated with corporate-liable devices, employee morale may suffer when employees are required to use organization-provided devices. Their dissatisfaction may result from using devices that are older or lack the functionality needed. This can lead to reduced productivity or, in extreme cases, attempts to breech security controls to use unauthorized personal devices. The traditional, corporateliable strategy has many advantages, including governance and control of the devices, as well as the potential for an overall reduction in cost to employees and the organization for mobilityrelated expenses. Personal-liable approach to mobility devices Many employees say they would prefer to use their own personal mobility devices for business calls, , and other work. Allowing the use of personally owned devices may boost employee morale and productivity and offer opportunities to reduce mobility-related expenses. However, in some cases the new expenses borne by employees may eliminate the goodwill associated with allowing employee-owned devices into the organization. Benefits of a personal-liable approach Depending on the personal device usage program, organizations may reduce their costs significantly. Many organizations offer their employees a fixed monthly stipend to help offset their monthly voice and data bill. This approach results in predictable mobile expenses for the corporation, and employees become responsible for the costs of their mobile devices and data plans. In this case, the mobility-related asset management expense associated with the acquisition, maintenance, and disposal of devices and the processing of payment for carrier invoices can be reduced or eliminated. In addition to the potential financial savings, organizations might receive other benefits such as being able to recruit and retain tech-savvy workers, who may have a strong attachment to a favorite mobility platform. When using a mobile device they like and with which they are familiar, employees can be more productive when working out of the office. Having a structured approach to personally-liable devices also reduces the likelihood of employees circumventing security controls to use unauthorized devices and allows the organization to implement policy and compliance requirements as a condition of use in the corporate environment. Additionally, organizations may be able to secure reduced monthly costs for service and premiere-level support from the carriers for their employees. 3

Allowing the use of personally owned devices may boost employee morale and productivity and offer opportunities to reduce mobilityrelated expenses. Costs for a personal-liable approach While the personal-liable model offers benefits for both employees and employers, security and governance become more complicated and expensive. When sensitive corporate information is stored on a corporate-owned device, the organization can implement and enforce strict controls on the operating system and other features of the device, such as Wi-Fi and Bluetooth to prevent unauthorized use of that sensitive information. Employees, however, are not likely to allow such an intrusive level of control over their own devices. To meet these compliance requirements, additional security tools, such as Network Access Control and Data Leak Prevention systems, may be required. Other solutions, including secure mobile messaging, mobile device management, and virtualization should be considered for segregation of personal data from corporate data, and to selectively delete corporate data in the event that the employee leaves or is terminated. Additional security measures may be required to mitigate the risks associated with employees installing applications from app stores. These untrusted applications may expose corporate data or infect other devices in the organization s network. In addition to security-related costs, the company might experience additional expenses to support multiple mobility platforms. With a small selection of corporate-liable devices, help desk support is limited to fewer devices. With the wider variety of devices that a personal-liable device program introduces, support costs may increase as more, and higher-skilled, help desk personnel are required. Similarly, application development costs may increase as the organization moves from developing applications for few platforms to a wider range of mobile devices. Dell s Mobile Application Platform helps to produce multi-platform tools that allows for one application to be deployed to a variety of mobile application platforms. Other concerns may be raised by human resources, finance, and corporate counsel. To mitigate risks to the organization, organizations must implement an employee agreement to address topics that include acceptable use of personal devices and corporate access to the employee s device. The financial arrangements relating to stipends or reimbursement of actual expenses should also be included in this employee agreement. Corporate counsel should carefully weigh any record-keeping requirements for SMS text messages or call logs made from mobile devices and evaluate potential legal consequences of capturing this information from employee-owned devices. Finally, employees may discover unexpected expenses associated with using their personal device for work. While their current voice and data plans may be sufficient for personal use, voice and data usage may expand dramatically when employees begin using their phone for work calls and applications. The increase in voice and data costs may be dramatic, especially for employees who travel internationally, where voice and data roaming charges are very expensive. In many cases, a stipend may not be sufficient to cover the increased costs. Alternatively, if the organization reimburses for actual costs, an employee may find that they spend several hours a month separating out their personal costs prior to submitting the bill for reimbursement. They may not be comfortable with providing their personal call detail records. Key considerations for mobility security Whether an organization chooses a corporate- or personal-liable model, or a hybrid, mobility security must be an integral part of an overall enterprise mobility strategy. This strategy should include the platform, applications, and data that will be offered through mobility technology, as well as expected users. It should also include an overall assessment of the organizations risk appetite. Dell s Enterprise Mobility Solutions can assist organizations in fulfilling their mobility strategy, while managing risk to an acceptable level. Mobile Device Management Mobile device management tools allow organizations to enforce corporate policies and validate security settings. Many tools offer an ability to delete all corporate data on the device, as well as data associated with specific applications. Secure Mobile Messaging Secure Mobile Messaging tools allow organizations to store corporate and PIM data in an encrypted container on the device, separate from the data stored in the native device clients. The secure mobile messaging tool provides a method to 4

Some secure mobile messaging tools also support message-level encryption that meets U.S. federal government standards. Mobile Application Platform Mobile Application Platforms provide a set of tools for the development of secure multi-platform mobile applications. These applications may be webbased, accessed via secure network connections, as well as applications that run in an encrypted container that prevents unauthorized access from other, malicious applications that may be installed on the device. In addition to these tools, new security policies and procedures may be needed to meet the challenges associated with this new mobility environment. Following are some questions to consider when deciding on what approach works best for your organization: Are there any specific concerns that would preclude the use of employee-owned devices? Information may be subject to Freedom of Information Act requests, or other regulatory or compliance requirements that preclude the use of personally-owned devices. Is there a catalog of devices that would be allowed to access enterprise applications and data? With each new platform supported in the environment, more management complexity is added. Even in a personal-liable or hybrid model, costs may increase as additional versions of enterprise applications must be developed and maintained. Is the organization willing to implement additional security controls to allow a broader range of devices? Not all mobility platforms offer the same intrinsic security capabilities. In some cases, deficiencies in a platform s security posture may be mitigated through the addition of security controls, either on the device or in the corporate network. Additional security measures may be required to mitigate the risks associated with employees installing applications from app stores. These untrusted applications may expose corporate data or infect other devices on the organization s network. Is the corporation willing to accept a short-term increase in risk to allow newer platforms access to data while the device s management and security tools mature? New platforms bring new opportunities and challenges. For each new device, and even operating system version, there may be a period of time when appropriate management and security tools do not exist. For corporate-owned devices, it may be an easy decision to delay upgrades. However, for personally-owned devices, employees may be unwilling to forego the latest updates. How will the organization respond to inappropriate material on a personally-owned device? This question may be one of the most critical and hardest to answer. Who decides what is inappropriate? Under what conditions could the organization examine the personal property of an employee? What are the laws in your jurisdiction, and do they differ whether the employee uses the device for their own convenience compared to when no alternative corporate-liable option is presented? If the risks associated with an all-encompassing personal-liable approach are too high, is there a subset of employees with a lower overall risk profile that might qualify for personally-owned devices? The personal-liable approach need not be all-or-nothing. While some employees or business units may pose too high a risk for using personally-owned devices, other employees may have a reduced risk profile that allows personally-owned devices. Some organizations take the approach that limited access to enterprise applications and data may be available to employees who otherwise would not need a corporate-provided smart phone. 5

6 Summary While a number of organizations consider implementing a personal-liable approach to mobile devices, careful consideration must be given to the benefits and consequences of this new approach. The finance department may view the potential reduction in phone bills as a driving force in transferring the liability for mobility costs to its employees. However, new risks associated with the loss of control over devices may outweigh any potential savings. Employees may be excited about the ability to use their preferred device for work. That enthusiasm will wane quickly when they begin to experience overage charges for their data plan. Human resources and corporate counsel will need to carefully consider the balance between employee privacy, recordkeeping requirements, and the obligation to create a workplace free of the inappropriate content that may be stored on employees devices. While it would be nice if there were a clear winner in the corporate-versus-personal liable debate, the appropriate approach will depend on the needs and risk appetite of your organization. Whether using either approach or both in combination, careful consideration of these topics is essential for a successful enterprise mobility security strategy.
