Abstract:
Registering a computer system for use in an enterprise. A method includes receiving, from a device management infrastructure of the enterprise, an executable system management component (SMC), and installing the SMC at a storage device. The method also includes executing the SMC, causing the computer system to register with the device management infrastructure, including applying a device settings policy to a configuration of the computer system. Executing the SMC also causes the computer system to configure itself to periodically execute a maintenance task received from the device management infrastructure. The method also includes periodically executing the maintenance task, causing the computer system to receive updated device settings policies from the device management infrastructure and apply the updated device settings policies to the configuration of the computer system, and to receive an updated application from the device management infrastructure and install the updated application at the computer system.

CROSS REFERENCE TO RELATED APPLICATION 
       [0001]    This application is a continuation of U.S. patent application Ser. No. 13/787,420, filed Mar. 6, 2013, entitled “LIMITING ENTERPRISE APPLICATIONS AND SETTINGS ON DEVICES,” and which issued as U.S. Pat. No. 9,245,128 on Jan. 26, 2016, the entire content of which is incorporated by reference herein in its entirety. 
     
    
     BACKGROUND 
     Background and Relevant Art 
       [0002]    Computers and computing systems have affected nearly every aspect of modern living. Computers are generally involved in work, recreation, healthcare, transportation, entertainment, household management, etc. 
         [0003]    Further, computing system&#39;s functionality can be enhanced by a computing systems ability to be interconnected to other computing systems via network connections. Network connections may include, but are not limited to, connections via wired or wireless Ethernet, cellular connections, or even computer to computer connections through serial, parallel, USB, or other connections. The connections allow a computing system to access services at other computing systems and to quickly and efficiently receive application data from other computing systems. 
         [0004]    Current networks have allowed many new and different types of devices to be networked. One of the major trends in IT in recent years has been the drive towards “consumerization of IT,” which is a term describing how consumer technology, from phones to PCs, is bleeding into business organizations in all forms and fashions. And increasingly, the devices that are showing up are owned by, and liable to the employee rather than the organization for which they work. This is seen most notably in the smartphone device category, but more recently also in tablets or other portable device form factors that are increasingly showing up in the workplace. As organizations embrace consumerization, IT must consider how much control they can exert over a user&#39;s device, whether personally owned or owned by the enterprise, and how much management of the device is “good enough.” 
         [0005]    The device may be stolen or the device may host a mobile app that turns out to be Trojan horses that collect saved passwords or log keystrokes and other data. Thus, there may be a desire to control what data and apps can be stored on the device. However, as the device may be used for personal purposes, and not just enterprise purposes, there may also be some desire on the user&#39;s part to have personal data and apps not be under enterprise control. Previous solutions are either too heavy handed with management and take complete control over users&#39; devices or are too light on management and security allowing near unfettered access by a user of enterprise resources using their devices. 
         [0006]    The subject matter claimed herein is not limited to embodiments that solve any disadvantages or that operate only in environments such as those described above. Rather, this background is only provided to illustrate one exemplary technology area where some embodiments described herein may be practiced. 
       BRIEF SUMMARY 
       [0007]    One embodiment illustrated herein includes a method of installing apps and setting configuration on a device. The method includes receiving user input. The user input indicates a level of control that a user is willing to give an enterprise over a device. The method further includes determining, based on the level of control indicated by the user, a set of apps allowed to install on the device. The set of apps allowed to install on the device is limited by the level of control indicated by the user. The method further includes authorizing installation of the set of apps on the device while restricting installation of other apps that would be authorized had the user selected a different level of control that the user is willing to give the enterprise over the device. 
         [0008]    This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

     DETAILED DESCRIPTION 
       [0017]    Embodiments described herein include functionality for managing devices, which in some embodiments may be personally owned devices that are used in an enterprise environment. In particular, a device may be generally controlled by a user and not the enterprise, but may still be able to be used in the enterprise environment with appropriate control on the device. In particular, the enterprise may exert control over certain aspects of the device, while allowing the user to control other aspects of the device without enterprise interference or intrusion. This management approach balances meeting the security needs of the enterprise while maintaining the user&#39;s control over the device and minimizing any impact of the device performance. Embodiments address how to deliver configuration and software that users need in the enterprise context, like apps and data-access on any device, with enough IT control to assert that the device is trustworthy, while avoiding compromising the user&#39;s privacy on their device. 
         [0018]    Various embodiments may exhibit various aspects. For example, embodiments may implement an enrollment experience where a user can go through a built in OS component to connect to the enterprise work environment. Alternatively or additionally, embodiments may exhibit a collection of limited amount of inventory that is enough to assess the device&#39;s security but not enough to take control of the device and intrude on the user&#39;s privacy. Alternatively or additionally, embodiments may exhibit performance aware on demand app distribution where a notification service is used to initiate the installation of apps. Alternatively or additionally, embodiments may exhibit disconnecting from an enterprise that blocks all the apps and/or resets settings obtained from the enterprise. 
         [0019]    Enterprise Device Management 
         [0020]    With more and more people providing their own hardware for work, “bring your own device” (BYOD) is becoming more commonplace and IT Pros want to have the confidence that they can support their clients who follow this trend. The presence of BYOD does not change the need for IT Pros to manage, secure, and remain accountable for the network assets of an organization. Written policies are often ineffective at enforcing enterprise policies. 
         [0021]    Embodiments illustrated herein may include functionality for managing personally owned device in an enterprise by delivering the settings and software that users need, like apps and data-access on any device, with enough IT control to assert that the device is trustworthy, while avoiding any compromise of the user&#39;s privacy on their personal device. It is understood that concepts described herein also are applicable to other types of devices that are used in an enterprise setting, such as enterprise-owned devices on which users expect privacy with respect to select applications, data, settings, etc. 
         [0022]    Referring now to  FIG. 1 , a device  102  is illustrated. The device  102  may be a computing device such as a cell phone, pda, tablet, laptop, or other device that a user may choose to connect to an enterprise environment network  110 . Some embodiments integrate a light management component (agent  104 ) built into the device&#39;s operating system  106  that can communicate with a management infrastructure  108  in the enterprise network  110  to deliver line of business (LOB) applications (sometimes referred to colloquially and herein as apps) to users. 
         [0023]    The management solution has two client installed portions: the system management component, which may be referred to herein as an agent  104 ; and a user interface, which may be referred to as the self-service portal, or SSP  112 , that the device user uses to browse for and install LOB apps made available to them. The SSP  112  may be implemented in a number of different ways, such as an app on the device  102 , a web page/service that runs in the user&#39;s browser on the device  102 , or other interface. Notably, a request to install an app for the user of the device  102  does not need to originate from the device  102  itself. In some embodiments, it may be done from another machine. In the illustrated example, however, both portions of the management solution installed at the client may be designed to be well behaved citizens of the operating system  106  in terms of user experience, power management/battery life, network awareness (for metered networks), and overall functionality. 
         [0024]    The agent  104  does most of the heavy lifting on the client device  102 . It configures the client device  102  to communicate with the organization&#39;s management infrastructure  108 ; periodically, or by some trigger of the management infrastructure  108 , synchronizes with the management infrastructure  108  to check for any updated LOB apps and apply the latest settings policies configured by IT for the device  102 ; and handles the actual download and installation of any LOB apps that the user wants to install. Finally, if the user or the administrator chooses to remove the device  102  from the management infrastructure  108 , it clears the configuration of the agent  104  itself and disables, or securely erases, any LOB apps the user installed from the SSP  112 . 
         [0025]    The following now illustrates additional details regarding connecting the client device  102  to the management infrastructure  108 . In some embodiments, connecting a client device  102  to the management infrastructure  108  begins with an IT administrator specifying the group of users, such as, for example, a group of Active Directory® (AD) (available from Microsoft® Corporation of Redmond Wash.) domain users who are authorized to connect devices  1022  into the network enterprise  110 . The administrator also has the option to specify the maximum number of devices allowed per user or other constraints related to per user enrollment policy. For example, other per user enrollment policy considerations may specify that a user can only enroll when on a particular network, with multi-factor authentication, within a given time period, etc. As illustrated in  FIG. 2 , an authorized user, selects a company apps link  202  of a user interface  200  and supplies their enterprise credentials  204 . The agent  104  then performs a service lookup to locate the organization&#39;s management infrastructure  108 . 
         [0026]    Once the agent  104  has found the right address, it establishes a secure connection to the management infrastructure  108  and authenticates the user. If the user is successfully authenticated and has been authorized by the administrator to connect devices (e.g. device  102 ), the enterprise network  110  issues the right commands to configure the agent  104  for its ongoing communications with the management infrastructure  108 . Once complete, the user is directed to install the SSP  112  while the agent  104  completes the connection in the background. Alternatively, the SSP  112  could be installed automatically by the management infrastructure at enrollment time. While in the example illustrated, a user has been authenticated to the management infrastructure  108 , in alternative or additional embodiments, the device itself may be authenticated to the management infrastructure. For example, the device  102  could be redirected to a management service which would allow the device to be enrolled on the company&#39;s behalf. 
         [0027]    Next, the agent  104  automatically initiates a session with the management infrastructure  108 , using the settings that it already obtained. This session and any subsequent sessions may be performed over a secure connection. This initial session completes the registration of the device  102  with the enterprise network  110  by supplying some basic device information such as the manufacturer and model of the device  102 , the operating system version of the device  102 , device capabilities, and other hardware information for the device  102 . This allows IT administrators to monitor what types of devices are connecting to the organization, so they can improve the apps and services they deliver to users over time. 
         [0028]    Following the initial session, the agent  104  initiates communication with the management infrastructure  108  in two circumstances: 
         [0029]    First, as a maintenance task that runs on a preset schedule, or from management infrastructure triggers or other triggers, that does not impact the user experience. The activities performed during these maintenance sessions focus on reporting updated hardware information to the management infrastructure  108 , applying changes to the settings policies for the device  102 , reporting compliance back to the management infrastructure  108 , and applying app updates to LOB apps, or retrying any previously failed LOB app installations initiated from the SSP  112 . 
         [0030]    Secondly, the agent  104  will communicate with the management infrastructure  108  anytime the user initiates an app installation from the SSP  112 . In some embodiments, these user-initiated sessions are solely focused on app installation and do not perform the maintenance and management activities described in the first case. 
         [0031]    Regardless of whether a session is initiated automatically by a scheduled maintenance task or manually by the user, the client  102  device continues to behave well relative to the state of the battery on the device and its current network conditions. 
         [0032]    Settings Policy Management 
         [0033]    As already discussed, access to LOB apps typically requires systems to comply with basic security and data protection policies. From the management infrastructure  108 , the IT administrator is able to configure a set of policies that they believe are important to give IT the assurances they need without seriously affecting the user&#39;s experience with their device. In particular, administrators can enforce password policies and turn off certain peripherals. 
         [0034]    In addition to the configurable policies described above, the agent  104  can also be used to automatically configure other settings such as network settings, VPN configuration, WiFi settings, etc., so that the managed device  102  can easily connect to an enterprise network  110 . Finally, the agent  104  can also monitor and report on compliance of the device  102  with a set of policies 
         [0035]    Leveraging this compliance information, IT administrators can more effectively control access to corporate resources on the enterprise network  110  if a device is determined to be at risk. Yet once again, the user&#39;s basic experience with the device is left intact and their personal privacy is maintained. 
         [0036]    In some embodiments, the policies that can be enforced by the enterprise or other third parties may be configurable by the user of the device  102 . For example, a user may be willing to accept some polices while refusing to accept other polices that the enterprise would like to enforce. Thus, a user can accept a level of control that the user is willing to give an enterprise over the device. This level of control indicated by the user of the device  102  may affect what settings the enterprise automatically configures on the device  102  and what apps the enterprise is willing to allow to be installed on the device  102 . 
         [0037]    For example, if a user is not willing to accept all policies that the enterprise would like to enforce, then the device  102  may only be allowed to install a limited set of apps on the device while being restricted from installing other apps on the device. Illustratively, the SSP  112  may provide a user interface that allows a user to select polices that the user is willing to accept. For example, the user interface may provide a list of policies with a set of check boxes where the user can select, by checking check boxes, which policies the user is willing to have enforced on the device  102 . Alternatively, a wizard interface or other interface may be employed to obtain information about what policies the user is willing to have enforced on the device  102 . 
         [0038]    The policies that the user may select from may include, for example, restrictions on the device. For example, such restrictions may include items such as requiring a password on the device, requiring certain apps or software to be installed on the device, requiring certain settings on the device, limiting the device to use with certain types or certain networks, etc. 
         [0039]    Alternatively or additionally, the policies the user may select from may include policy related to data access controls on the device  102 . For example, the user may indicate that the enterprise is able to completely lock the device, erase all data on the device, restore the device to factory settings, erase all enterprise data on the device, erase data associated with certain apps on the device (such as enterprise apps, mail apps, etc.), etc. 
         [0040]    LOB App Management 
         [0041]    The previous discussion has been focused on the mechanics of the client device  102  and management infrastructure  108  along with the needs of the IT administrator. However, an important aspect of the above is the benefit that can be provided to the end user by enabling access to their LOB apps. 
         [0042]    There are several different categories and types of apps that IT can publish for users in the SSP  112 . For example, IT can publish: internally developed apps developed by the enterprise; apps produced by independent software vendors that are licensed to the organization for internal distribution; web links that launch websites and web-based apps directly in the browser; links to app listings in other application marketplaces (this is a convenient way for IT to make users aware of useful business apps that are publicly available); etc. 
         [0043]    Because the user specified his or her corporate credentials as part of the initial connection with the management infrastructure  108 , as illustrated in  FIG. 2 , the IT administrator can then specify which apps are published to each user individually. As a result, the user only sees those apps that are applicable to them in the SSP  112 .  FIG. 3  illustrates an example of the SSP  112  user experience for a user browsing for LOB apps in the SSP  112  for a fictional enterprise called “Woodgrove.” 
         [0044]    Notably, embodiments may be implemented in a closed app market environment. In such an environment, the typical user scenario is that users are only allowed to install apps from a pre-approved set of available apps from an authorized market. For example, using the Windows Phone™ available from Microsoft® Corporation of Redmond Wash., a user is typically only able to install apps from the Microsoft® official application marketplace which offers apps that have been evaluated and pre-approved for offering in the official application marketplace. In other embodiments, the closed app market environment may be closed as to certain types of apps, but open to other types of apps. For example, using Windows 8 available from Microsoft Corporation of Redmond Wash., a user is able to only install Windows Store Apps from the official application marketplace in the Windows 8 interface (such as that illustrated in  FIG. 3 ), while other apps can be installed in the desktop interface with little or no restriction. 
         [0045]    Embodiments may be extended to allow apps that are of a style or format to be typically offered in a closed app market environment, but that are not generally offered in the closed app market environment to nonetheless be “side-loaded” so as to allow enterprise specific apps, not offered in the closed market, to nonetheless be installed on the device  102 . For example, a Windows® Phone would be able to install apps not offered in the official application marketplace. Alternatively, a Windows® 8 device would be able to install Windows Store Apps not available in the official application marketplace. 
         [0046]    In some embodiments, this, or enabling certain settings or management functions, may be accomplished by installation of a side loading key  114  on the device  102  which, so long as the side loading key  114  is valid, allows the device  102  to side load apps  116  from a content server  118  of the management infrastructure, where the apps  116  are not offered generally in the closed app market  120 , such as the apps  122 . 
         [0047]    However, while the apps  116  that can be installed using the side loading key  114  are not generally offered in the closed app market  120 , in some embodiments, the apps  116  must still be validated and authorized to be installed on the device by a central authority. For example, the same central authority that validates and authorizes apps provided in the closed app market  120  may validate and authorize the apps intended to be side loaded onto the device  102 , so long as the device  102  has a valid side loading key  114  (or other indication that the device is authorized to side load apps). 
         [0048]    The side loading key  114  can be obtained in a number of different ways. For example, in some embodiments, the side loading key  114  may be purchased from the closed app market  120 . In other embodiments, the key may be purchased by the enterprise from a central authority. In some embodiments, a single side loading key  114  may be valid for a particular number of installs onto devices. For example, the side loading key may be able to be installed on multiple different devices at any given time. 
         [0049]    In some embodiments, when the user chooses to install an app from the SSP  112 , the request is sent to the management infrastructure  108  and a download link is provided to the agent  104 . The agent  104  then downloads the app, verifies the validity of the content, checks the signature, and installs the app. All of this typically occurs within seconds and is generally invisible to the user. In the event that an error occurs during any part of this process (e.g. the location of the content is unavailable), the agent  104  queues the app for a retry during its next regularly scheduled maintenance session. In either case, the agent  104  reports the state of the installation back to the management infrastructure  108 .  FIG. 4  details this interaction. 
         [0050]    In particular,  FIG. 4  illustrates at  402  that the SSP  112  obtains a targeted app list from a management service  128  at the management infrastructure  108 . The management service  128 , as illustrated at  404 , at the management infrastructure  108  sends back an app list to the SSP  112  where the app list includes an enumeration of apps available to be installed by the device  102 . As illustrated at  406 , the user  126  interacts with the SSP  112  and requests installation of an app. As illustrated at  408 , the SSP  112  requests that the user requested app be installed by the management service  128 . As illustrated at  410 , the management service  128  confirms the request. As illustrated at  412 , the SSP  112  pokes the agent  104  indicating to the agent that the app selected by the user  126  should be installed. As illustrated at  414 , the agent  104  confirms the poke to the SSP  112 . As illustrated at  416 , the agent  104  requests app details and confirms the installation request by the user  126  to the management service  128 . As illustrated at  418 , the management service acknowledges the app requests to the agent  104 . As illustrated at  420 , the agent  104  requests app content from the content service  118  in the management infrastructure  108 . As illustrated at  422 , the content service  118  returns the app content to the agent  104  at the device  102 . As illustrated at  424 , the agent  104  communicates with a package manager  130  at the device  102  indicating that the app should be added for the user  126 . As illustrated at  426 , the package manager  130  indicates that installation of the app is complete. As illustrated at  428 , the agent  104  informs the management service  128  that the app has been installed. As illustrated at  430 , the management service  128  confirms to the agent  104  that the installation of the user selected app has been recorded. 
         [0051]    In some alternative embodiments, the closed app market  120  itself may have certain app offerings available that are only available to devices with a side loading key installed on the device  102 . For example, the closed app market  120  could provide one set of apps  122  generally to devices, but provide additional apps  124  for installation to devices based on side loading keys installed on the devices. The additional apps available for installation may be dependent on what side loading key is installed on the device. Thus, the closed app market  120  could maintain a set of apps, on behalf of the enterprise, for installation on enterprise authorized devices. 
         [0052]    As part of its regular maintenance sessions, the agent  104  will inventory which LOB apps are currently installed and report that information back to the management infrastructure  108  so the IT administrator can effectively manage their LOB apps. In some embodiments, only apps that were installed via the SSP  112  and the client device  102  are included in this inventory from a device. In some embodiments, generally available apps installed from a closed app market are not reported as part of the inventory. In some embodiments, the agent  104  may be restricted to only be able to inventory enterprise apps  116  and is not able to inventory apps  122  on the device  102  that the user has installed for personal use. 
         [0053]    Anytime the IT administrator publishes an update for an app that has been installed on an enterprise authorized device  102 , the agent  104  will automatically download and install the update during its next regular maintenance session. Alternatively, during a regular maintenance window the management infrastructure  108  may detect that an update is available and applicable, and as a result, notify the user 
         [0054]    Disconnecting from the Management Infrastructure  108   
         [0055]    Details are now illustrated on how to disconnect a device from the management infrastructure  108 . Disconnecting may be initiated either locally by the user or remotely by the user or the IT administrator. Users may choose to disconnect for any number of reasons, including leaving the enterprise or getting a new device and no longer needing access to their LOB apps on the old device. Administrators may choose to disconnect a user&#39;s device after they have left the enterprise or because the device is regularly failing to comply with the organization&#39;s security settings policy. In another alternative embodiment, the enterprise may automatically disconnect a user device  102  if the device has not connected to the enterprise network  110  for a given period of time. 
         [0056]    During disconnection, the agent  104  performs a number of actions (and/or ceases performing a number of actions). For example, the agent  104 . removes access to all the apps that the user obtained from the enterprise. In some embodiments, the agent  104  can block access to the apps  116  or can completely remove the apps  116  from the device  102 . The agent  104  ceases enforcement of the settings policies that the management infrastructure  108  has applied. The agent  104  reports successful deactivation to the management infrastructure  108  if the administrator initiated the process. The agent  104  removes the agent  104  configuration, including the scheduled maintenance task. Once completed, the agent  104  remains dormant unless the user reconnects it to the management infrastructure  108  or another management infrastructure. 
         [0057]    The following discussion now refers to a number of methods and method acts that may be performed. Although the method acts may be discussed in a certain order or illustrated in a flow chart as occurring in a particular order, no particular ordering is required unless specifically stated, or required because an act is dependent on another act being completed prior to the act being performed. 
         [0058]    Referring now to  FIG. 5 , a method  500  is illustrated. The method  500  includes acts for installing apps on a device. The device is generally configured to be used in a closed market environment that only allows generally available apps of the closed market to be installed. The method  500  includes determining that the device has been authorized to install apps outside of a set of apps generally available from the closed market and from a set of apps available only to users of a particular enterprise (act  502 ). For example, the method  500  may be performed where determining that the device has been authorized to install apps outside of a set of apps generally available from the closed market comprises determining that a side loading key has been installed on the device. Such an example is illustrated in  FIG. 1  by using the side loading key  114  with the device  102 . 
         [0059]    The method  500  further includes determining that an app, that is not generally available from the closed market, has been verified by a central authority (act  504 ). The method  500  may be practiced where determining that an app that is not generally available from the closed market has been verified by a central authority includes determining that the app has been verified by a central authority responsible for the closed market. For example, if Microsoft® runs a closed market, but the app is not provided by the closed market run by Microsoft® Corporation, Microsoft® Corporation could nonetheless verify the app. For example, as illustrated and  FIG. 1 , the entity responsible for maintaining the market  120  and verifying the apps  122  may also verify the apps  116  in spite of the fact that the apps  116  are not offered in the market  120 . Thus the apps  116  available from the enterprise network  110  nonetheless have an authority chain to a central authority. 
         [0060]    The method  500  further includes installing the app on the device in spite of the fact that the device is generally configured to be used in a closed market environment (at  506 ). 
         [0061]    The method  500  may further include providing a user interface to a user to allow a user to select the app from among a set of apps available for devices authorized to connect to the particular enterprise; receiving user input selecting the app; notifying a service that the user has selected the app; receiving a notification from the service that the app is available to be installed; and wherein installing the app on the device is performed in a fashion that minimizes disruption to the device. Examples of this functionality are illustrated in  FIGS. 3 and 4 . In particular,  FIG. 3  illustrates a user interface that may be presented to a user to allow a user to select apps for installation.  FIG. 4  illustrates an example of communication between various entities to allow a user to indicate what apps the user would like to install in the process for installing the apps. In some such embodiments, the app may be installed when the device determines that it has sufficient free resources to install the app without serious impact to the user experience of the device. 
         [0062]    The method  500  may further include maintaining an enumeration of apps from the set of apps available only to users of a particular enterprise that have been installed on the device. In particular, a manifest may be maintained at the device  102  and the agent  104  that enumerates the various apps that have been installed on the device  102 . This can be used to report to an enterprise central authority information about what apps are installed on the device  102 . 
         [0063]    The method  500  may further include providing a report to an enterprise administrator. The report may include an enumeration of all apps from the set of apps available only to users of a particular enterprise that have been installed on the device without identifying in the report other apps that have been installed on the device. For example, the report may identify any the apps  116  that have been installed on the device  102  but will not identify any apps selected from the set of apps  122  that have been installed on the device  102 . 
         [0064]    The method  500  further includes various acts for removing the device  102  from the enterprise network  110 . For example, the method  500  may include deauthorizing the device such that the device can no longer install apps from among the set of apps available only to users of a particular enterprise; disabling or deleting any apps from among the set of apps available only to users of a particular enterprise that have already been installed on the device; and making data associated with any apps from among the set of apps available only to users of a particular enterprise that have already been installed on the device inaccessible. In some embodiments, this may be performed in response to the device not contacting a management infrastructure for a pre-determined period of time. In alternative or additional embodiments, this may be performed in response to a user indicating a desire to disconnect the device from the enterprise. In yet another additional or alternative embodiment this may be performed in response to an administrator indicating a desire to disconnect the device from the enterprise. 
         [0065]    Referring now to  FIG. 6 , a method  600  is illustrated. The method  600  includes acts for installing apps and setting configuration on a device. The method  600  includes receiving user input from a user of a device, the user input indicating a level of control that the user is willing to give an enterprise over the device (act  602 ). The method  600  may be practiced where the user input comprises a user indicating that the enterprise may enforce one or more restrictions on the device. For example, the one or more restrictions may include one or more of requiring a password, requiring certain apps to be installed on the device, limiting access of the device to certain networks or the like. Alternatively or additionally, the method  600  may be practiced where the user input comprises a user indicating that the enterprise may control data access on the device. For example, the user input may indicate that the enterprise may perform one or more of locking the device, erasing all user data on the device, restoring the device to factory settings, erasing all enterprise data on the device, erasing data associated with certain apps on the device, or the like. The method  600  may be practiced where the user input comprises a user selecting a plurality of items from a predetermined list, such as a checkbox list, that the user is willing to let the enterprise control or restrict on the device. 
         [0066]    The method  600  further includes determining, based on the level of control indicated by a user, a set of apps that the user is allowed to install on the device (act  604 ). The set of apps that the user is allowed to install on the device is limited by the level of control indicated by the user. 
         [0067]    The method  600  further includes authorizing the device to install the set of apps while restricting the device from installing other apps that would be authorized had the user selected a different level of control that the user is willing to give the enterprise over the device (act  606 ). For example, a device, such as device  102 , may be allowed to install some apps, but not other apps based on the user setting and the level of control that the user is willing to allow the enterprise to have over the device  102 . In some embodiments, the method  600  may be practiced where the device is generally configured to be used in a closed market environment that only allows generally available apps of the closed market to be installed on the device, but the device is authorized to install apps outside of a set of apps generally available from the closed market and wherein the set of apps are available only to users of the particular enterprise. 
         [0068]    Further, the methods may be practiced by a computer system including one or more processors and computer readable media such as computer memory. In particular, the computer memory may store computer executable instructions that when executed by one or more processors cause various functions to be performed, such as the acts recited in the embodiments. 
         [0069]    Embodiments of the present invention may comprise or utilize a special purpose or general-purpose computer including computer hardware, as discussed in greater detail below. Embodiments within the scope of the present invention also include physical and other computer-readable media for carrying or storing computer-executable instructions and/or data structures. Such computer-readable media can be any available media that can be accessed by a general purpose or special purpose computer system. Computer-readable media that store computer-executable instructions are physical storage media. Computer-readable media that carry computer-executable instructions are transmission media. Thus, by way of example, and not limitation, embodiments of the invention can comprise at least two distinctly different kinds of computer-readable media: physical computer readable storage media and transmission computer readable media. 
         [0070]    Physical computer readable storage media includes RAM, ROM, EEPROM, CD-ROM or other optical disk storage (such as CDs, DVDs, etc.), magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store desired program code means in the form of computer-executable instructions or data structures and which can be accessed by a general purpose or special purpose computer. 
         [0071]    A “network” is defined as one or more data links that enable the transport of electronic data between computer systems and/or modules and/or other electronic devices. When information is transferred or provided over a network or another communications connection (either hardwired, wireless, or a combination of hardwired or wireless) to a computer, the computer properly views the connection as a transmission medium. Transmissions media can include a network and/or data links which can be used to carry or desired program code means in the form of computer-executable instructions or data structures and which can be accessed by a general purpose or special purpose computer. Combinations of the above are also included within the scope of computer-readable media. 
         [0072]    Further, upon reaching various computer system components, program code means in the form of computer-executable instructions or data structures can be transferred automatically from transmission computer readable media to physical computer readable storage media (or vice versa). For example, computer-executable instructions or data structures received over a network or data link can be buffered in RAM within a network interface module (e.g., a “NIC”), and then eventually transferred to computer system RAM and/or to less volatile computer readable physical storage media at a computer system. Thus, computer readable physical storage media can be included in computer system components that also (or even primarily) utilize transmission media. 
         [0073]    Computer-executable instructions comprise, for example, instructions and data which cause a general purpose computer, special purpose computer, or special purpose processing device to perform a certain function or group of functions. The computer executable instructions may be, for example, binaries, intermediate format instructions such as assembly language, or even source code. Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the described features or acts described above. Rather, the described features and acts are disclosed as example forms of implementing the claims. 
         [0074]    Those skilled in the art will appreciate that the invention may be practiced in network computing environments with many types of computer system configurations, including, personal computers, desktop computers, laptop computers, message processors, hand-held devices, multi-processor systems, microprocessor-based or programmable consumer electronics, network PCs, minicomputers, mainframe computers, mobile telephones, PDAs, pagers, routers, switches, and the like. The invention may also be practiced in distributed system environments where local and remote computer systems, which are linked (either by hardwired data links, wireless data links, or by a combination of hardwired and wireless data links) through a network, both perform tasks. In a distributed system environment, program modules may be located in both local and remote memory storage devices. 
         [0075]    Alternatively, or in addition, the functionally described herein can be performed, at least in part, by one or more hardware logic components. For example, and without limitation, illustrative types of hardware logic components that can be used include Field-programmable Gate Arrays (FPGAs), Program-specific Integrated Circuits (ASICs), Program-specific Standard Products (ASSPs), System-on-a-chip systems (SOCs), Complex Programmable Logic Devices (CPLDs), etc. 
         [0076]    The present invention may be embodied in other specific forms without departing from its spirit or characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
