Mobile Application Control

Abstract

A device user may determine what applications from a set of applications may access the corporate network and which applications do not access the network. An indication of the limits on what a corporate network may access on a user personal device may provided to a user and either accepted or rejected. The user, if the user agreement is accepted, may receive a list of allowed applications and modify the list by removing applications on the list which the user does not want to send data to the corporate network. Both the user and a corporate network administrator may view the user accepted limits and track what user device applications actually have accessed the corporate network to confirm compliance with the limits.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the priority benefit of U.S. Provisional Application Ser. No. 61/973,248, titled "Mobile Connect," filed Mar. 31, 2014, the disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

[0002] Consumers continue to push for a mechanism that allows them to use their own device to perform typical work tasks. In most cases, these devices are owned by the individual user, which means the company may have zero control over them. Because companies have little if any control over these user devices, there is concern regarding providing the device access to corporate remote networks due to the potential for attacks vectors (nefarious applications, leaking, tampering, or otherwise disclosing of critical intellectual property owned by company). The market has coined the term "unmanaged device" or "BYOD" (bring your own device) to represent any device that is not owned or controlled by the company that needs access to the corporate network so the employee can do their work. In most cases, this device is owned by the employee requesting access. Some companies require employee devices to be put under mobile device management (MDM) control before allowed onto the corporate network, but such a configuration is not really zero control.

[0003] Most mobile solutions are all or nothing--all data is shared or no data is shared with respect to a corporate intranet (i.e., an appliance based network). With the advent of BYOD, users need to access the corporate intranet but do not want their personal information to be available to the corporate intranet. Likewise, the corporate intranet may not want to risk exposure to certain content on the user device that is not germane (or appropriate) for the corporate network.

[0004] Secure communication with a corporate network can be achieved through virtual private network (VPN) connections. Current VPN clients that provide application level control block traffic in that VPN application running on the client device. For example, some companies provide a per-app VPN solution. Despite current VPN per application solutions, there are still concerns regarding the vulnerability of corporate network access from personal user devices.

[0005] There is a need in the art for managing access to corporate networks by user's personal devices at the application level that protects corporate interests while protecting personal data of users.

SUMMARY OF THE CLAIMED INVENTION

[0006] An appliance works in conjunction with an agent on a remote device to control application access to a corporate network. In conjunction with an SSL tunnel and policy operating at the appliance, granular application control may be implemented. In particular, a device user may determine what applications from a set of applications may access the corporate network and which applications do not access the network. A user agreement indicating of the limits on what a corporate network may access on a user personal device may be provided to a user and either accepted or rejected. The user, if the user agreement is accepted, may receive a list of allowed applications and modify the list by removing applications on the list which the user does not want to send data to the corporate network. Both the user and a corporate network administrator may view the user accepted limits and track what user device applications actually have accessed the corporate network to confirm compliance with the limits.

[0007] An embodiment may include a method for establishing a connection. The method may include establishing a connection between a user client device and a server. The user client device may have a plurality of applications and be associated with a user. A user agreement regarding what a corporate network will access on the user client device may be presented to the user through the user client device and from the server. A confirmation may be received of the user agreement from the user by the client device. The client may be provided with access to the corporate network by the server.

[0008] In an embodiment, a system for establishing a connection may include a device having a processor, memory, and an agent stored in memory and executable by the processor to establish a connection between a user client device and a server, the user client device having a plurality of applications and associated with a user, present to the user through the user client device a user agreement on what a corporate network will access on the user client device, receive a confirmation of the user agreement from the user by the client device, and provide the client access to the corporate network.

DETAILED DESCRIPTION

[0014] An intranet appliance works in conjunction with an agent on a remote device to control application access to a corporate network. In conjunction with an SSL tunnel and policy operating at the appliance, granular application control may be implemented. In particular, a device user may determine what applications from a set of applications may access the corporate network and which applications do not access the network.

[0015] A device user may determine what applications from a set of applications may access the corporate network and which applications do not access the network. A user agreement indicating what a corporate network may access on a user personal device may provided to a user and either accepted or rejected. The user, if the user agreement is accepted, may receive a list of allowed applications and modify the list by removing applications on the list which the user does not want to send data to the corporate network. Both the user and a corporate network administrator may view the user accepted limits and track what user device applications actually have accessed the corporate network to confirm compliance with the limits.

[0016] FIG. 1 illustrates a block diagram of a client communicating with a remote server. The system of FIG. 1 includes client device 110, network 120, VPN appliance 130, and corporate network 140. VPN appliance 130 may include tunnel server 136, policy server 134, and data store 138. Corporate network 140 may include one or more servers such as corporate server 142.

[0017] Client 110 may include a user device that is not controlled by the entity that provides 1 1 corporate network 140. Client 110 may be implemented as a mobile device such as a smart phone, tablet or laptop computer, a desk top computer, or other computing device.

[0018] Network 120 may include one or more networks used to communicate data between client device 120 and, ultimately, corporate server 142. For example, network 120 may include a private network, public network, the Internet, an intranet, a local area network, a wide area network, a wireless network, a cellular network, and a combination of these networks.

[0019] Tunnel server 130 on VPN appliance 125 may establish a VPN tunnel and communicate with client device 110 and serve as an intermediary between client device 110 and corporate server 142. This VPN may be used to allow applications on the client device 110 to communicate with a corporate server 142 in a secure fashion even though traffic is flowing over a public network 120.

[0020] 1The policy server may include one or more applications that perform functionality discussed herein, such as for example generating and applying policy rules. Datastore 138 may store and process data, and is accessible by servers 132, 134 and 136. For example, datastore 138 may store communication log data, application lists, application information, and other data. The client device 110 may communicate with tunnel server 136 to authorize access to corporate server 142. The client may also communicate through an API Server 132 which is a peer to the tunnel server and is used to authenticate the user, retrieve the list of applications, authenticate a device, and other functionality. Both API Server 132 and Tunnel Server 136 may communicate with policy server 134 to obtain policy decisions to help provide responses to client requests

[0021] Corporate server 142 of corporate network 140 may be accessed by the user device 110 through tunnel server 136 of VPN appliance 130. In this case, tunnel server 136 may receive and analyze all network traffic to confirm the traffic is from an authorized application before the traffic may access the corporate server. Access to corporate server 142 and other resources on corporate network 140 is determined by both policy server 134 and tunnel server 136. Tunnel Server 136 provides policy enforcement and traffic analysis while policy server 134 is the policy decision point, and the two servers work in concert to both analyze traffic and apply policy.

[0022] FIG. 2 illustrates a block diagram of a client having an agent. Agent 240 may communicate with tunnel sever 230 and API Server 280 to implement client side functionality of the present technology. For example, agent 240 may provide an interface to a user for selecting one or more of a set of applications allowed to access the corporate network 140, collect data at the device and provide the data to tunnel server 136 or API server 132, and other functionality.

[0023] Agent 240 may communicate with applications 210-230 on device 110 and may generate and manage application objects 250-260. An application may correspond to each application object. An application object may include the application name, version, and other data for a corresponding application. Agent 240 may transmit application information within each application object to tunnel server 136 or API server 132 to allow policy server 134 to make access control decisions.

[0024] FIG. 3 illustrates a method for providing application access to a network. A VPN connection is established between the tunnel server and an agent 240 on the client at step 310. The agent may initiate the VPN establishment by sending a VPN request to the VPN appliance.

[0025] A user is authenticated at step 310. User authentication is performed to identify the user of the device. A user device is then classified to determine if it meets acceptable parameters at step 315. In some instances, an administrator defines a set of device attributes, and the system may attempt to find a set of attributes that match the device. Classification of the device may include retrieval of a unique equipment identifier along with other device attribute data. The unique equipment identifier and device attribute data may be collected by an agent and transmitted to policy server 134. The attribute data may be used by the policy server to determine if client device 110 may allow for application control by the policy server via the agent.

[0026] Once the user is authenticated and the device is classified, the data store is queried to determine if a matching entry for the user and device exist. If the user and device combination are found in the data store, then the user and device have established a connection with the corporate network before and the version of the user agreement previously agreed to by the user is checked against the most recent version at step 317. If the user has already accepted the current user agreement at step 317, and therefore the most recent user agreement has not changed from the stored user agreement for the user and device combination, then the method continues to step 325 and the present system does not provide the user with the same user agreement and a portion of or all of step 320 (and corresponding method of FIG. 4) will not per performed for the current session.

[0027] If the device requires a new user agreement to be accepted, either because the user and device combination is not found in the data store or the current version of the user agreement does not match the stored version of the user agreement, the method continues from step 317 to step 320.

[0028] User acceptance of a user agreement is verified at step 320. Once a user accepts a user agreement, the user may be authorized for the corporate network access. In some embodiments, a policy server determines authorization of the user, device, and checks access permissions. The policy allows for application access to particular data for a particular device type and user type. Once the user has accepted the user agreement, the user may be authorized to access a corporate network. More detail for user acceptance of the user agreement is provided with respect to FIG. 4.

[0029] Application traffic may be transmitted to the corporate network at step 325. An agent on the client device may monitor communication data and provide information to the user of the device regarding what applications are communicating with the corporate network.

[0030] An audit may be performed on the application data sent to the corporate network at step 330. The server will collect data as packets are transmitted to the corporate network regarding which user and device are sending traffic. The data may include an application identifier and version specific hash, which is collected for any application that sends data to the corporate network. The server may receive the data and store the data for each session between the user and device combination and the corporate network.

[0031] The administrator may access the stored session data on the VPN appliance and identify which applications on the particular user device and for a particular user have sent data to the corporate network. The user may access data stored by the agent on the client device to identify which applications have sent data to which destination on the corporate network. The user and administrator may also access the limits agreed to by the user regarding application data to be sent to the corporate network. From this information, the user or administrator may each determine whether the application data transmitted complied with the limits agreed to by the user, thereby auditing the application data access by the corporate network.

[0032] FIG. 4 illustrates a method for verifying user acceptance of a user agreement. The method of FIG. 4 provides more detail for step 325 of the method of FIG. 3. A user is provided with a user agreement regarding corporate network access to application data from applications on the user's device at step 405. The user agreement is a mutual contract between the corporate network operator and the end user where the end user can choose to accept it to be granted access to the corporate network or decline and end their session. The language contained within the user agreement may be drafted by the corporate network legal counsel.

[0033] The user agreement may specify policies and rules regarding how the network access may access data, when it may access data, and generally inform the user of application data access over the corporate network. In some instances, the user agreement may be a contract offer to the user. The indication received by the user device from a server and provided to the user through an interface of the user device. A determination is then made as to whether the user accepts the user agreement at step 410. If the user does not accept the limits indicated, access to a corporate access is denied to the user and user device combination at step 415. If the user has not accepted the user agreement, upon a subsequent login attempt, the user may again be prompted to comply with the user agreement. If the user does accept the limits, the user's acceptance of the limits and the indication of the limits are stored at step 420. If the user accepts the user agreement a copy of the user agreement is stored on the client device. A record for the user, device and user agreement version number may also be created or updated at the VPN appliance to reflect the user's acceptance. The user's acceptance will not be required from the user again for the same user agreement for the particular user and user device combination.

[0034] The agent on the client device is provided with a list of applications from the VPN appliance, wherein the listed applications are allowed to access the corporate network at step 425. The list of applications is determined by the access policy configured by an administrator which contains detailed information on which users, devices, applications, and destinations should be granted access. If the received application list is the same list as that received during the previous session, the agent does nothing (e.g., will not present the newly received list to the user) and the method of FIG. 4 continues to step 440 (i.e., no input is received from the user as no applications from the newly received list are provided to the user).

[0035] If the list is different from the previous session for the user and device, or the list is provided during the first session for the user and device combination, the agent on the client device presents the list of applications to the user via an interface of the device. The user may choose to block applications on this list from accessing the corporate network and have network traffic data flow over the VPN. For each application, the application type may be specified along with particular versions or configurations of the application that may be allowed to access the corporate network. A determination is then made as to whether input is received from the user to remove applications from the list at step 430. If such input is received, the user selected applications are removed from the list at step 435 and the method continues to step 440. In some instances, if the user removes all the applications from the list, the session may be terminated. Otherwise, network access may be provided to application data from applications on the list at step 440. At any time during the session, the user may change the applications on the current list which are authorized to send data to the corporate server.

[0036] If the user removes an application from the list by deselecting it, the client device will not send traffic from that application to the corporate network. A network administrator may not be notified that the user chose to limit the application set to less than what was authorized by the network administrator. Hence, what the user decides to allow or not allow with the company to use on their device is not shared with the network administrator. For example, if the user would like to user a particular network browser to access monster.com to look for a new job, the user likely will not want to have to explain to her supervisor why they disabled it.

[0037] At any time during the current session, a network administrator may access the version number of the user agreement accepted by the user, as this information is stored in the data store 138. The user may also access a copy of the user agreement that they have previously agreed to, and may access a copy which has been stored on their device. The user may access a copy at any time via a menu setting on a UI provided by the VPN agent 240.
