DETAILED DESCRIPTION
The present disclosure is directed to a system and method for enabling access to resources in an enterprise perimeter when accessing services by connecting to a network through a wireless connection with another device. For example, a tablet computer, when connecting to a network through a wireless connection with another device, may access resources in an enterprise perimeter based on an enterprise identifier assigned to the tablet computer and the connecting device. A perimeter may generally refer to a logical separation of resources such as applications, stored data and network access. Resources included in a perimeter may be encrypted and password protected to securely separate those resources from resources in different perimeters. For example, resources in different perimeters may be prohibited from transferring data. In some implementations, perimeters may include personal perimeters and enterprise perimeters (or corporate perimeters). A personal perimeter may generally refer to a perimeter created by default for a user and managed by the same An enterprise perimeter may generally refer to a perimeter created for or by a user and managed by a remote management server or service (e.g., a BlackBerry Enterprise Server (BES) or a BlackBerry Playbook Administration Service (BPAS), etc.).
When connecting to a network through a wireless connection with another device, a wireless communication device (e.g., tablet computer) may access enterprise resources using tethering techniques, such as a connecting device, with another device. Tethering can happen, for example, when the connecting device is a cellular phone (e.g., BlackBerry smartphone), which has both cellular services and wireless local area network (WLAN) services (e.g., Wi-Fi services) enabled, while the wireless communication device (e.g., tablet computer) has WLAN services but not cellular services. The cellular phone may access, through a cellular network, enterprise resources that is associated with an enterprise perimeter included in the wireless communication device. The cellular phone may perform tethering to the wireless communication device through a direct wireless connection (e.g., Wi-Fi, Bluetooth). In some implementations, a user can access, when tethering, resources included in an enterprise perimeter to access services in an enterprise network. Alternatively or in addition, the wireless communication device may directly access enterprise resources. Regardless, the wireless communication device may compare an assigned enterprise identifier with an enterprise identifier assigned to the connecting device and grant access to resources in the enterprise in response to the identifiers matching.
FIG. 1 is an example system 100 for granting access to resources of an enterprise perimeter of a wireless communication device (e.g., tablet computer) when connecting to a network through a wireless connection with another device. For example, the system 100 may identify enterprise identifiers assigned to each device by an enterprise and grant access to resources in an enterprise perimeter if the identifiers match. An enterprise identifier can include an email address, an employee number, a client certificate, a cryptographic token, a server name, or other character strings. In some implementations, the system 100 may execute one or more of the following: transmit to an enterprise a request to access a server resource account; receive an indication that access has been granted and identifies an enterprise identifier assigned to the device; generate an enterprise perimeter including the enterprise identifier and resources for accessing the server resource account; receive a request to connect the current device to a network using another device; in connection with connecting with the devices, identifying an enterprise identifier assigned to the connecting device; receiving a request to access a resource in an enterprise perimeter of the current device; comparing the enterprise identifier of the current device to that of the connecting device; granting access to the resource in response to the identifiers matching; generating a separate unknown user perimeter in response to the identifiers not matching; or other processes. By assigning enterprise identifiers to device and connecting with another device with the same enterprise identifier, the system 100 may grant access to resources to an existing enterprise network when connecting to the enterprise network through a wireless connection with another device.
At a high-level description of the elements, the system 100 includes a first user device 102 communicably coupled to a second user device 104. The second user device 104 is communicably coupled to the cellular network 106 and the enterprise network 108. The first user device 102 includes perimeters 110a and 110b configured to prevent access to included resources, and the second user device 104 includes perimeter 110c configured to prevent access to included resources. The enterprise network 108 includes an enterprise server 112 for providing access to server resource accounts. As for a high level description of operation, the device 102 may wirelessly transmit a request to connect to a network using the device 104. The device 104 may verify the user and transmit information indicating that the connecting request is granted. The transmitted information may include an enterprise identifier. While connected to network through the device 104, the device 102 may receive a request to access a resource in an enterprise perimeter 110. In response to at least the request, the device 102 may compare the enterprise identifier of the device 102 to the enterprise identifier of the device 104. In the event that the identifiers match, the device 102 may grant access to the resource in the enterprise perimeter 110. In the event that the identifiers do not match, the device 110 may generate a separate unknown user perimeter 110 including resources for accessing an account from the enterprise server 112. In some implementations, when connecting to a network through a wireless connection with another device, the device 102 may be granted network connectivity to the Internet, network connectivity to the (enterprise) intranet, access personal or enterprise data on the device 110, or other access.
Turning to a more detailed description of the elements, the devices 102 and 104 may be any local or remote computing device operable to receive requests from the user via a user interface, such as a Graphical User Interface (GUI), a CLI (Command Line Interface), or any of numerous other user interfaces. Thus, where reference is made to a particular interface, it should be understood that any other user interface may be substituted in its place. In various implementations, the devices 102 and 104 may comprises electronic computing devices operable to receive, transmit, process and store any appropriate data associated with the communication system 100. As used in this disclosure, the devices 102 and 104 are intended to encompass any electronic device or computing device that has wireless communication capability. For example, the devices 102 and 104 may be a tablet computer, a personal computer, a laptop computer, touch screen terminal, workstation, network computer, kiosk, wireless data port, wireless or wireline phone, personal data assistant (PDA), smartphone, at least one processor within these or other devices, or any other suitable processing device. For example, the devices 102 and 104 may comprise wireless communication devices that include an input device, such as a keypad, touch screen, mouse, or other device that can accept information, and an output device that conveys information associated with the operation of the resources, including digital data, visual information, or GUI. The devices 102 and 104 may include fixed or removable storage media such as a magnetic computer disk, CD-ROM, flash memory, or other suitable media to both receive input from and provide output to users through the display, such as a GUI. In addition, the devices 102 and 104 may include less or more perimeters 110 as compared with the illustrated perimeters 110.
In some implementations, the device 102 and the device 104 may wirelessly communicate using Bluetooth, Wi-Fi, WiMAX, or other wireless communication protocols. The device 104 may wirelessly communicate with the cellular network 106. In these instances, the device 104 may be any wireless communication device that includes cellular network communication capability, i.e., comprises a cellular device 104. For example, the device 104 may be a 2nd generation (2G), a 3rd generation (3G), or a 4th generation (4G) telecommunication device. Example 2G, 3G and 4G telecommunication network standards include Global System for Mobile communication (GSM), Interim Standard 95 (IS-95), Universal Mobile Telecommunications System (UMTS), CDMA2000 (Code Division Multiple Access), 3GPP long-term evolution (LTE), LTE-Advanced (LTE-A), and others. In these instances, the wireless communication device 102 may communicate with the cellular device 104 through a wireless connection 114. For example, the cellular device 104 may be a connecting device, and information communicated between the wireless communication device 102 and the enterprise server 112 may be tethered by the cellular device 104.
In some implementations, the wireless communication device 102 may access the enterprise server 112 based on tethering via the cellular device 104. For example, when the wireless communication 102 does not have cellular network access functionality, and the enterprise server 112 is not communicably coupled to the cellular network 106, the wireless communication device 102 may not be able to communicate directly with the enterprise server 112. In such case, if the cellular device 104 (e.g., a BlackBerry smart phone) includes tethering functionality and can perform cellular network communications with the enterprise server 112, the cellular device 104 may then be used as a connecting device (or a relay) to enable communication between the wireless communication device 102 and the enterprise server 112. The wireless communication device 102 and the cellular device 104 may communicate using a direct wireless connection (e.g., Bluetooth, Infrared, optical connection, WiFi, WiMax, RFID, NFC, etc.), a wired connection (e.g, USB, Firewire, etc.), or personal or local area networks. The cellular device 104 may have access to an enterprise account maintained on the enterprise server 112. The cellular device 104 may also have an enterprise perimeter 110c associated with the enterprise account generated locally on the cellular device 104. When tethering, a user of the device 102 may access the enterprise account. In some implementations, the device 102 may grant access to resources an enterprise perimeter 110 when connecting to a network through the device 104. For example, the device 102 may request an enterprise identifier from the device 104 and determine whether the enterprise identifier matches the enterprise identifier of the device 102. In the case of a match, the device 102 grants access to the resources when connecting to a network through the device 104. If there is not match, the device 102 generates a separate unknown user perimeter including resources for accessing the account.
The devices 102 and 104 also include perimeters 110 configured to prevent access to internal resources. The perimeter 110 may include password protection, encryption, and other process for controlling access to resources assigned to the perimeter or internal resources. Resources may include at least one of data, network access, applications, configurations, policies, or others. In some implementations, the perimeters 110a-c may be enterprise perimeters created by an administrator for an enterprise and may be managed by the remote management server 112. As described previously, the enterprise account may be, for example, an account that pushes data to the device 102 (e.g., ActiveSync). When the wireless communication device 102 accesses the account, the perimeter 110 may include policies identifying one or more security settings for the enterprise account. These policies may be maintained and enforced by an enterprise server (not shown) residing in an enterprise network (or corporate network) 104a. in some implementations, the perimeters 110 may include at least one of data, network access, applications, configurations, or policies 120.
In some implementations, the cellular network 106 is provides connectivity with other wireless communication systems and wired communication systems. The wireless communication system may communicate with wireless device 104 using a wireless technology such as one based on orthogonal frequency division multiplexing (OFDM), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT-SOFDM), Space-Division Multiplexing (SDM), Frequency-Division Multiplexing (FDM), Time-Division Multiplexing (TDM), Code Division Multiplexing (CDM), or others. The wireless communication system may transmit information using Medium Access Control (MAC) and Physical (PHY) layers. The techniques and systems described herein may be implemented in various wireless communication systems such as a system based on Long Term Evolution (LTE), LTE-Advanced (LTE-A), Global System for Mobile Communication (GSM) protocols, Code Division Multiple Access (CDMA) protocols, Universal Mobile Telecommunications System (UMTS), Unlicensed Mobile Access (UMA), or others. The cellular network 106 may include one or more base station for wirelessly communicating with the device 104. In addition, the cellular network 106 may be connected to the enterprise network 108.
The enterprise network 108 is a network associated with an enterprise. The enterprise may comprise a corporate or business entity, a government body, a non-profit institution, or any other organization coupled to the devices 102 and 104. In some implementations, the enterprise may be the owner of devices 102 or 104. In some implementations, the device 102 or 104 may be owned the user, and, in these cases, the user may an enterprise to configure an enterprise perimeter 110 on the personal device 102. Of course, the enterprise may also lease the devices 102 or 104 or may hire contractors or agents who are responsible for maintaining, configuring, controlling, and/or managing the devices 102 and 104. In the illustrated implementation, the network 108 facilitates communication with the devices 102 and 104. The network 108 may communicate, for example, Internet Protocol (IP) packets, Frame Relay frames, Asynchronous Transfer Mode (ATM) cells, voice, video, data, and other suitable information between network addresses. In addition, while the enterprise network 108 is illustrated as a single network, the network 108 may comprise a plurality of networks. In short, the enterprise network 108 is any suitable network that configured to communicate with the device 104. In the illustrated implementation, the enterprise network 108 includes the enterprise server 112.
The enterprise server 112 may include any software, hardware, firmware, or a combination thereof configured to manage access to one or more server resource accounts. The enterprise account may be, for example, an ActiveSync email, calendar, or contacts account. The enterprise account may be associated with an enterprise perimeter 110 such that the perimeter 110 may secure applications, data, and security policies for accessing the account. The enterprise server 112 may maintain or enforce resources, settings, and security policies associated with the enterprise perimeter 110 and accounts. The enterprise server 112 may receive a request associated with the enterprise account and initiate generation of a perimeter 110 in connection with providing access to the account. In some implementations, the enterprise server 112 may transmit information indicating security policies for accessing a server resource account. As previously mentioned, the enterprise server 112 may also assign an enterprise identifier to a device in connection with granting access to a server user account. For example, the enterprise server 112 may transmit the enterprise identifier in connection with transmitting the security policies to the device 102 or 104. The enterprise identifier may include a network address, an employee number, or other character strings.
FIG. 2 is a communication system 200 including an example device 202. The example device 202 comprises an example implementation for device 102 and 104. As illustrated, the communication system 200 includes the device 202 communicably coupled to networks 204a and 204b (individually and collectively referred to as 204). In addition, the device 202 may interact with a device owner 205, one or more users 206a and 206b (individually and collectively referred to as 206), one or more administrators 208a-c (individually and collectively referred to as 208), a combination of the foregoing, or others. The wireless communication device 202 includes perimeters 210a-c, and each perimeter includes data 212, network access resource 214 for providing access to networks, applications 216 for providing services to users 206, configuration files 218 for configuring resources, and policies 220 for defining policies for accessing enterprise accounts. As for a high-level description of operation, the device 202 receives a request to access resources for accessing an enterprise account in the enterprise network 204a when connecting to a network through a wireless connection with another device. In response to the request, the device 202 determines whether the enterprise identifier assigned to the device 202 matches the connecting device. If matching, the device grants access to the resources in the perimeter 210. Otherwise, the device 202 generates a separate unknown user perimeter for accessing the account.
The device 202 includes the perimeters 210a-c configure to prohibit access to internal resources by external resources. In some implementations, the perimeter 210 may include password protection, encryption, and other process for controlling access to resources assigned to the perimeter or internal resources. A perimeter 210 may be generated by the device owner 205, a user 206, an administrator 208, or others. In some examples, the perimeter 210a may be a personal perimeter created by default for the user 206a and managed by the user 206a. In some examples, the perimeter 210a may be an enterprise perimeter created by an administrator 208a for an enterprise and may be managed by a remote management server. In some implementations, each personal perimeter 210 may be associated with a personal account, and each enterprise perimeter 210 may be associated with an enterprise account. In addition, a given perimeter 210 may be accessed by the device owner 204, a user 206, an administrator 208, a combination of the foregoing, or others. In some implementations, each perimeter 210 may be associated with a single user 206 while each user 206 may access multiple device perimeters 210. For example, the user 206a may access resources within both the perimeter 210a and the perimeter 210b. The user 206b may have access to resources in only one perimeter 210c. The device owner 205 may have the ability to remove individual perimeters 210 from the wireless communication device 202. In some implementations, the user 206 may set up or log in to an enterprise account via a user interface. As described previously, the enterprise account may be an account that pushes data to the device 202 (e.g., ActiveSync). When the wireless communication device 202 accesses the account, the perimeter 210 may include policies identifying one or more security settings for the enterprise account. These policies may be maintained and enforced by an enterprise server (not shown) residing in an enterprise network (or corporate network) 204a. While the perimeters 210 are illustrated as including all aforementioned resources such as data 212, one or more network access resources 214, one or more applications 216, one or more configuration files 218, and one or more policies 220, the perimeters 210 may include some, all or different resources without departing from the scope of the disclosure.
In the illustrated implementation, a given perimeter 210 may include data 212, network access resource 214, applications 216, configuration files 218, a policy 220, a combination of the foregoing, or other resources. The data 212 may include various objects or data, including classes, frameworks, applications, backup data, business objects, jobs, web pages, web page templates, database tables, repositories storing business and/or dynamic information, and any other appropriate information including any parameters, variables, algorithms, instructions, rules, constraints, or references thereto associated with the purposes of the wireless communication device 202 and its applications 216. Additionally, the data 212 may include any other appropriate data, such as data associated with VPN applications, firmware logs and policies, firewall policies, a security or access log, print or other reporting files, as well as others. The data 212 may be stored in any memory or database module and may take the form of volatile or non-volatile memory including, without limitation, magnetic media, optical media, random access memory (RAM), read-only memory (ROM), removable media, or any other suitable local or remote memory component.
The network access resource 214 may include any parameters, variables, policies, algorithms, instructions, settings, or rules for granting access to the network 204a or 204b or other network. For example, the network access resource 214 may include or identify firewall policies for accessing the enterprise network 204a. In some implementations, the network access resources 214 include or otherwise identify one or more of the following: a username; a password; a security token; a Virtual Private Network (VPN) configuration; firewall policies; a communication protocol; encryption key certificates, or others.
The applications 216 may comprise any application, program, module, process, or other software that may execute, change, delete, generate, or otherwise manage business information according to the present disclosure. In certain cases, the communication system 200 may implement a composite application 216. For example, portions of the composite application may be implemented as Enterprise Java Beans (EJBs) or design-time components may have the ability to generate run-time implementations into different platforms, such as J2EE (Java 2 Platform, Enterprise Edition), ABAP (Advanced Business Application Programming) objects, or Microsoft's .NET. Further, while illustrated as internal to the wireless communication device 202, one or more processes associated with the application 216 may be stored, referenced, or executed remotely. For example, a portion of the application 216 may be an interface to a web service that is remotely executed. Moreover, the application 216 may be a child or sub-module of another software module or enterprise application (not illustrated) without departing from the scope of this disclosure. In some implementations, the application 216 may be a hosted solution that allows multiple parties in different portions of the process to perform the respective processing. For example, the enterprise network 202 may access the application 216 on the wireless communication device 202 or even as a hosted application located over network 202b without departing from the scope of this disclosure. In another example, portions of the application 216 may be used by the user 206 working directly at the wireless communication device 202, as well as remotely via enterprise network 202a. In some implementations, the applications 216 may be configured to access at least one of a personal perimeter 210 or an enterprise perimeter 210, which may be referred to as dual mode applications or hybrid mode applications. A dual mode application 216 may access either a personal perimeter 210 or an enterprise perimeter 210. A hybrid mode application 216 may access both a personal perimeter 210 and an enterprise perimeter 210.
The configuration file 218 may include any parameters, variables, policies, algorithms, instructions, settings, or rules for configuring software of the wireless communication device 202. For example, the configuration file 218 may include a table that identifies settings for one or more applications 216. In some implementations, the configuration file 218 identifies initial settings for one or more applications 216. In addition to user applications 216, the configuration file 218 may identify settings for other types of applications such as operating system settings. The files 218 may be written in ASCII and line-oriented, with lines terminated by a newline or carriage return/line feed pair, depending on the operating system.
The policy 220 may include any parameters, variables, policies, algorithms, instructions, settings, or rules for accessing accounts. For example, the policy 220a may identify one or more accounts external in the network 204 and information for accessing the accounts. For example, the policy 220 may include a password, an encryption algorithm and key, and access rules. In some implementations, the policy 220 may include or otherwise identify one or more of the following: a password; an encryption key; access rules; a specific account; a network address; internal resources; a user; an owner; an administrator; a time period; or other information. With regard to external accounts, the policy 220 may identify a specific account and associated rules or information for accessing the external account. In some implementations, a policy 220 may define or otherwise identify a process for user authentication prior to enabling access to an account. For example, the policy 220 may identify the type and content of user authentication (e.g., password strength, lifecycle) to apply to an account-access request.
The wireless communication device 202 may be connected to multiple networks, such as the enterprise network 204a and the public network 204b. The enterprise network 204a is a network associated with an enterprise. The enterprise may comprise a corporate or business entity, a government body, a non-profit institution, or any other organization connected to the wireless communication device 202. The enterprise may be the owner 204 of the wireless communication device 202. Of course, the enterprise may also lease the wireless communication device 202 or may hire contractors or agents who are responsible for maintaining, configuring, controlling, and/or managing the wireless communication device 202. In the illustrated implementation, the networks 204 facilitate wireless and/or wireline communication with the wireless communication device 202. The networks 204 may communicate, for example, Internet Protocol (IP) packets, Frame Relay frames, Asynchronous Transfer Mode (ATM) cells, voice, video, data, and other suitable information between network addresses. In addition, while the enterprise network 204a and the public network 204b are each illustrated as a single network, each network 202 may comprise a plurality of networks. In short, the enterprise network 204a and the public network 204b are any suitable network that configured to communicate with the device 204.
FIG. 3A is an example screen 300 for accessing resources in an enterprise perimeter using a GUI. The GUI may be presented on a touchscreen display 300 of a wireless communication device (e.g., a BlackBerry Playbook tablet PC), as described with regard to FIG. 2. As shown in the first screen 300 of the example GUI, the left hand side of the GUI displays content included in a personal perimeter 302. The personal perimeter 302 may be a default perimeter of the wireless communication device, as described with regard to FIG. 2. Since the personal perimeter 302 may be a default perimeter, a user of the wireless communication device may have the permission to access and manipulate the documents under the personal perimeter 302. The right hand side of the GUI displays information associated with an enterprise perimeter (or a corporate perimeter) 304. As indicated, the user has not logged in to its enterprise account and verified enterprise identifiers with the connecting device. Thus, the corporate screen associated with the enterprise perimeter 304 is locked. The user may slide or click the scroll bar 306 to trigger a password authentication process.
FIG. 3B is a second screen 320 of the example GUI. In this implementation, the screen 320 shows a pop-up window 322 prompting to receive the password to log in to the enterprise account. The account settings may accordingly be added to the wireless communication device. As described with regard to FIG. 2, log in to the enterprise account or adding the enterprise account to the wireless communication device may create a new record at the password manager on an enterprise server, which may trigger an event for the enterprise server to “push down” settings/policies to the wireless communication device. Upon authenticating the password, the wireless communication device may determine whether access to the resources is granted by determining whether the enterprise identifiers of the current device match the connecting device.
FIG. 3C is a third screen 340 of the example GUI. In these implementations, the personal perimeter 302 and the enterprise perimeter 342 are displayed separately. The documents included in the personal perimeter 302 and the enterprise perimeter 304 are logically separated from each other and stored in the wireless communication device. The user may not be permitted to transfer documents between the personal perimeter 302 and the enterprise perimeter 342. As such, the corporate data included in the enterprise perimeter 342 may be secured.
FIG. 4 is a flow chart illustrating an example method 400 for granting access to resources in an enterprise perimeter when connecting to a network through a wireless connection with another device. The illustrated method is described with respect to system 100 of FIG. 1, but this method could be used by any other suitable system. Moreover, the system 100 may use any other suitable techniques for manufacturing the system 100. Thus, some of the steps in this flowchart may take place concurrently and/or in a different sequence than as shown. System 100 may also use methods with additional steps, fewer steps, and/or different steps, so long as the methods remain appropriate.
Method 400 begins at step 402 where a request to enable access of a current device through a wireless connection with another device. For example, the device 102 in FIG. 1 may receive a request from a user to connect to device 104. At step 404, a request to connect is transmitted to the other device. In the example, the device 102 may wirelessly transmit to the device 104 a request to connect device 102 with a network through the device 104. Next, at step 406, an enterprise identifier for the current device is identified. Again in the example, the device 102 may identify an enterprise identifier assigned to the device in connection with generating the enterprise perimeter 110. A response indicating that the connecting request is received and identifying an enterprise identifier assigned to the other device at step 408. Again turning to the example, the device 104 may wirelessly transmit a response to the device 102 that indicates the connecting request is granted and an enterprise identifier assigned to the device 104. If the identifiers match at decisional step 410, then, at step 412, the current device grants access to resources in the enterprise perimeter. In some implementations, creation of duplicate or redundant perimeters can be advantageously avoided. In addition, a plurality of resources in an enterprise perimeter may be accessed when connecting to a network through a wireless connection with another device as compared to a perimeter for each resource. If the identifiers do not match, the device generates a separate unknown user perimeter including resources for accessing the account.
A number of embodiments of the invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. Accordingly, other embodiments are within the scope of the following claims.
