PAR SCÉNARIO D’UTILISATION
Define the right bring-your-own-device (BYOD), choose-your-own-device (CYOD) and corporate-owned, personally-enabled (COPE) policies for your organization, backed by complete technologies for enterprise mobility management (EMM).
Employee choice has become a cornerstone of mainstream IT strategy. By allowing people to choose the best devices for their needs, organizations can improve productivity and flexibility as well as job satisfaction. During the first wave of consumerization, these initiatives focused on bring-your-own-device (BYOD) programs and policies. Choose-your-own-device (CYOD) soon followed, allowing users to choose a company-owned device from a small pool of company-issued devices to use for work purposes. More recently, corporate-owned, personally-enabled (COPE) programs let users to choose a company-owned device from an approved list and use their own apps as well as corporate apps on the device. While the nuances of BYOD, CYOD and COPE can vary, including their approach to cost sharing and compensation, they share most of the fundamental principles— including their security implications. Any time both personal and corporate content exists on a device, IT must ensure that effective policies and technologies are in place to protect business information— without impeding the experience or productivity of the user.
Guiding principles for a successful BYOD, CYOD or COPE strategy
People should have the freedom to choose the type of device they use at work, including the same devices they use in their personal lives, and move seamlessly across devices over the course of the day. IT should be able to deliver on-demand files, apps and desktops to any device, anywhere, over any connection, while maintaining uniform and efficient security, policy enforcement, compliance and control through a single point of management.
Based on a technology foundation of enterprise mobility management, desktop and app virtualization and secure file sharing, as well as proven best practices for BYOD, CYOD and COPE, this strategy enables the organization to:
Recognizing that employees often work best when they’re allowed to choose their own tools, BYOD policies let people use their own devices, whether occasionally, primarily or exclusively, for work. As mobility and consumerization continue to transform IT, CYOD and COPE have emerged as alternatives that combine freedom of choice with increased control for IT. COPE can also be implemented side-by-side with CYOD or BYOD as a hybrid strategy to empower mobility in the right way for different users and groups. For example, COPE provides a way to ensure choice and mobility for employees who might not be able or willing to use their own personal devices at work, or who might otherwise be unsuitable for a BYOD or CYOD option.
The reality is that many people are already bringing their own devices to work, whether sanctioned or not. Without a coherent, comprehensive strategy for BYOD, CYOD or COPE, encompassing both policy and technology, an organization can face significant risks from security and compliance gaps to escalating IT complexity.
From a technology perspective, the most obvious question—especially where BYOD and CYOD are concerned—is how people will be able to access enterprise applications and corporate data and files on their personal devices. Simply installing apps directly on the device would raise serious security, privacy and compliance risks, license management issues and support complications, as well as restricting employee choice to Windows-based devices—and leaving other consumer devices out of the picture. For BYOD and CYOD as well as COPE, IT must also prevent the corporate apps and data on the device from being exposed to risk through the personal content it may also contain, such as when someone uses a personal, consumer-grade file sharing service to store and sync corporate data, or when a virus introduced through a personal game exposes corporate data stored on a device.
For this reason, any BYOD, CYOD or COPE program must include technologies to enable completely device-independent computing through enterprise mobility management (EMM), Windows desktop and app virtualization and secure file sharing supplemented by online collaboration and remote support services. With this approach, IT can provide optimal freedom for people while maintaining security and control. People gain single-click secure access to all of their Windows, web, SaaS and mobile apps through a unified app store on any device, over any network, with single sign-on and seamless session roaming across locations, networks and devices. IT gains a single point of control to provision and de-provision apps of all types quickly, whether to provide new resources or to cut off access when it is no longer needed or appropriate. In most scenarios, business information remains secure in the datacenter; in cases where it has to reside on the endpoint, it is protected through containerization, encryption and remote wipe mechanisms. An EMM solution that provides mobile application management (MAM) and mobile content management (MCM) capabilities in addition to mobile device management (MDM) allows IT to take a granular, app-by-app approach to security instead of or in addition to device-level controls.
In this way, IT can simplify management and reduce costs while empowering people to work easily, securely and seamlessly across any type of device, regardless of who owns the device. By leveraging the ability to granularly manage data, and application information, sensitive data can be protected while freeing IT from the need to manage someone’s personal device. IT gains identitybased provisioning and control of apps, data and devices, automatic account de-provisioning for terminated users and selective wipe of lost devices.
BYOD, CYOD and COPE policies can vary significantly from organization to organization depending on your priorities and concerns, and should be designed in consultation with HR, finance, legal and IT security teams. In general, the main differences between BYOD, CYOD and COPE deal with costs. BYOD users pay for their own devices and data plans, sometimes with a partial or full stipend provided by the company. For COPE and CYOD, the company pays directly for the device and data usage. A BYOD policy may also need to address considerations beyond the scope of COPE and CYOD, such as the question of whether employees should be paid overtime for checking email after hours or on weekends.
The following section presents guidelines and best practices for BYOD, CYOD and COPE policy development, as well as their implementation through Citrix solutions including Citrix Endpoint Management , Citrix Virtual Apps , Citrix Receiver , Citrix Gateway, Citrix Content Collaboration and Podio .
A successful BYOD, CYOD or COPE initiative combines simplicity for people with effective security, control and management for IT. While the temptation can be strong for IT to develop specific policies for every conceivable scenario, the reality is that most considerations can be addressed through the application of a few simple, consistent principles. In most cases, IT can think about how to manage and provide secure access to data and applications in terms of people, complemented with role-based management, configuration and security of personally-owned and approved devices to protect the organization against threats, data loss and non-compliant usage.
Organizations should make clear who in the organization is allowed to use personal or companyowned devices, whether on an ad hoc basis to supplement a corporate endpoint, as a permanent replacement for a corporate device or anything in between. This can be seen as a privilege to be earned, a response to employee demand, a requirement for certain types of roles, an excessive risk for some use cases or, most likely, a combination of these things.

Figure 2 – Citrix Endpoint Management simplifies device enrollment. Citrix Endpoint Management allows IT to enroll users manually or through file import. Autodiscovery simplifies the enrollment process for users, who can use their network user names and Active Directory passwords to enroll their devices, rather than having to enter server details.
Programs that involve the replacement of a corporate device with an employee-owned device, often with a stipend provided to the employee, involve their own set of considerations. One way to determine who should be eligible for this type of program is to apply criteria such as worker type, frequency of travel, performance or whether an individual requires offline access to sensitive data. However eligibility is defined on a broad level, managers should always have final approval over which team members are appropriate candidates to receive a stipend to replace their corporate device with one of their own choosing. Managers can also be advised to apply BYOD, COPE or CYOD within the context of other departmental incentives, privileges and disciplinary measures.
Contractors are generally ideal candidates for BYOD. Many organizations already expect contractors to bring their own devices, and requiring them to do so aids independent contractor compliance.
CYOD and COPE allow IT to avoid having an unmanageable diversity of devices in the enterprise environment by limiting the type of mobile devices your company will support. The granularity of this policy will depend on your user requirements, security risks and support resources; in general, the more granular your policy is in terms of device types, OS versions and model numbers, the more resources you’ll need to adequately test and support the specified devices. A more granular policy may also be more restrictive on your users—for example, by allowing only a particular iPhone model or a particular version of the Android OS.

BYOD participants should be required to buy their personal devices through normal consumer channels rather than an organization’s purchasing department. This helps maintain clear lines of ownership as well as ensures that participants have a direct relationship with their hardware vendor. You may want to make employee discounts available to them, if covered under your corporate vendor relationships. Some people may need or wish to supplement their device with peripheral equipment such as monitors or keyboards while at the office. In this scenario, make sure to specify who will procure and own each item.
Once your BYOD, CYOD or COPE initiative has been designed, communication is vital to a successful implementation. People should receive guidance to help them decide whether to participate and how to choose the right device for their needs. They should also understand their mobile responsibilities including how data can be accessed, used and stored, and the appropriate way to set up and use work-related accounts for unmanaged consumer apps and services. Work and business data should be kept strictly segregated to support e-discovery requirements and data retention policies; similarly, work emails should never be sent from personal accounts. Acceptable use policies should apply the same way on BYO devices as they do on corporate devices.
It’s also important to provide a user adoption program to help participant get up and running. A welcome email with a link to a self-service portal can help people become more productive, more quickly.
One of the primary benefits of BYOD is the ability to reduce costs by having people pay part or all of the cost of various devices used for work, and getting IT out of the business of procuring and supporting an expanding array of hardware throughout the enterprise. This is especially true in cases where a corporate-owned device will no longer be provided. On average, companies provide stipends in the range of 18-20 percent, though some pay more, and others offer no stipend or compensation at all. Participants should be aware that any stipend will be treated for tax purposes as income. In regions with higher personal income tax rates, you may want to increase the stipend accordingly to keep the net subsidy consistent for all participants. Any BYOD policy, with or without cost-sharing, should make clear who will pay for network access outside the corporate firewall, whether via 3G, public Wi-Fi or home broadband.
If you choose to provide a subsidy, it should reflect the full participation lifespan of each individual. Subsidies should be renewed at a regular interval to ensure that personal devices do not age beyond what would be expected for an enterprise device. If a participant leaves the company during a BYOD cycle, you may want to reclaim a portion of the current stipend.
Cost sharing has implications for the introduction of BYOD in the organization. An all-at-once rollout can increase cost as people sign up—and claim their stipends—at all points in the endpoint refresh cycle. Offering the program to people as they come to the end of their device lifecycle will spread out the impact. Organizations that do not offer a stipend can encourage full participation from day one.
A crucial requirement for both employee-owned and company-owned devices is to protect data without impacting user experience. For programs that allow personal apps and data on devices used for work, MAM makes it possible to keep personal and corporate apps, as well as their data, strictly separate from corporate content.
While the installation of applications directly on non-corporate devices can increase risk, a mobility program that combines enterprise mobility management, desktop virtualization and secure file sharing makes this unnecessary. All business information remains secure within the datacenter, residing on the endpoint only in isolated, encrypted form, and only when absolutely necessary. In cases where data does need to reside on the mobile device, company data can be protected through containerization, encryption and remote wipe mechanisms. To prevent exfiltration, IT can implement policies to disable printing or access to client-side storage such as local drives and USB storage.
On mobile devices, access to apps and data can be controlled, secured and managed with policies based on device ownership, status or location. IT can enroll and manage any device, detect jailbroken devices and perform a full or selective wipe of a device that is out of compliance, lost, stolen or belongs to a departed employee or contractor. Application security is ensured through secure application access via app tunnels, blacklisting, whitelisting and dynamic, context-aware policies.
Figure 4 – Mobile application management (MAM) protects company data. Citrix Endpoint Management provides granular app-level security controls by allowing you to add features to existing in-house and third-party mobile apps. Examples include provisioning, custom authentication requirements, per-application revocation, data containment policies, data encryption and per-application virtual private networking.
To protect the enterprise network, some organizations apply network access control (NAC) technology to authenticate people connecting to the network and check whether their devices have up-to-date antivirus software and security patches. Citrix Gateway is another option for providing additional secure access capabilities. Citrix ADC provides granular, policy-based control including app-level single sign-on, micro-app VPN and strong passwords.
Outside the firewall, virtualization and encryption can allay most of the security vulnerabilities of Wi-Fi, WEP encryption, open wireless, 3G/4G and other consumer-grade access methods. On mobile devices, application security is ensured through secure application access via app tunnels, blacklisting, whitelisting and dynamic, context-aware policies. Network security capabilities provide visibility into and protection against internal and external mobile threats; blocking of rogue devices, unauthorized users and non-compliant apps; and integration with security information and event management (SIEM) systems.
In the event that a BYOD participant leaves the organization, the relevant policy is breached or a personally-owned device is lost or stolen, IT should have a mechanism to terminate access instantly to data and apps, including automatic de-provisioning of work-related SaaS accounts and selective wipe of lost devices. This functionality is also essential for company-owned COPE or CYOD devices, making it possible to re-allocate a corporate-owned device to a new user without the possibility that data left on the device will fall into the hands of a user who isn’t authorized to access it.
Instead of allowing open BYOD, in which people can bring any device to access enterprise apps and data, some organizations choose a managed approach. In this scenario, IT manages the personally-owned device directly, including registration, validation, authorization and device resource access.
Monitoring and management
For BYOD, CYOD and COPE alike, ongoing monitoring and management are essential to ensure policy compliance and determine ROI. If violations are found, IT should remind users of the relevant policy and take the actions specified therein. Some EMM solutions increase IT productivity and effectiveness by automating several aspects of monitoring and management, such as specifying the actions to be taken in response to various violations. These might include fully or selectively wiping the device, setting the device to out-of-compliance, revoking the device, or sending a notification to the user to correct an issue within a time limit—such as by removing a blacklisted app—before more severe action is taken.
Figure 5 – A Citrix Endpoint Management dashboard provides IT with easy visibility into the mobile environment.
Figure 6 – Citrix Endpoint Management automates monitoring and management tasks.
Citrix Endpoint Management helps to reduce by automating several aspects of monitoring and management. For example, IT configure Citrix Endpoint Management to automatically detect a blacklisted app (for example, Words with Friends). Options including specifying a trigger that sets the user’s device out of compliance when Words with Friends is detected on their device. The action then notifies them that they must remove the app to bring their device back into compliance. You can set a time limit for how long to wait for the user to comply before taking more serious action, such as selectively wiping the device.
A BYOD program often reduces the total maintenance required for each device because the user is also the owner. This being said, the policy should spell out explicitly how various support and maintenance tasks will be addressed and paid for. When a personally-owned device has replaced a corporate device, there may be a higher expectation of IT support—but this should be defined narrowly to avoid exposing IT to greatly increased complexity and workload. Under most CYOD or COPE programs, IT is entirely responsible for device support and maintenance.
Citrix enables organizations to support BYOD, CYOD and COPE through enterprise mobility management, Windows desktop and app virtualization, secure file sharing, collaboration and remote support. In this way, IT can make enterprise apps and secure file sharing and sync available on any device people bring in to work while maintaining security and control.
Citrix solutions address all the key capabilities required to make BYOD, CYOD and COPE simple, secure and effective for any organization.
