Companies, enterprises, governments, agencies and other types of organizations may implement digital workspace solutions to allow users to access electronic resources, such as websites, web applications, software-as-a-service (SaaS) applications, virtual desktops, etc. Users may access electronic resources using personal devices and/or devices provided by an organization. An organization may implement security controls to manage access to various electronic resources. For example, company may prevent its employees from accessing certain websites using a company-owned device or a device connected to an internal company network. As another example, a company may protect certain electronic resources behind a firewall so that users can only access then when connected to an internal company network.
This Summary is provided to introduce a selection of concepts in simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key or essential features or combinations of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
It is appreciated herein that, although security controls exist for managing access (or navigation) to electronic resources, such controls may not be satisfactory or adequate to cover the full range of digital workspace solutions implemented and provided by a particular organization. For example, in order to enforce desired access policies, an organization may provide managed applications, such as the organization's browser application (also referred to herein as a “web browser” or more simply a “browser”), for use by its users to access electronic resources, such as the organization's software-as-a-service (SaaS) applications and web applications. However, when users navigate to or otherwise or access electronic resources using native or local browsers or using applications that open an accessed resource in a native or local browser, the organization is “out of the loop” with respect to the navigation to the electronic resource and unable to apply its access policies.
In some cases, users may be inconvenienced by access policies implemented by an organization. For example, an access policy may prevent access of certain insecure electronic resources (e.g., gmail.com) using an application other than a managed application (i.e., an application that is managed by the organization) even when the application is being used within the organization's network. This may be because accessing the insecure electronic resource may cause execution of malicious software, for example. In this case, if the user uses an application that is not a managed application and attempts to navigate to an insecure electronic resource, an applied access policy can prevent this navigation and generate an error notification to the user. Even though the attempted navigation is using an application that is running on the organization's network, the navigation is blocked by the applicable security policy, and the user is inconvenienced in having to then use a managed application to navigate to the insecure electronic resource.
While extensions (e.g., browser extensions) and plug-ins may provide controls for managing navigation to, or access of, electronic resources, users using their personal computing devices may not want these extensions and plug-ins installed on their personal devices. Moreover, the organization may not have the ability or capability to develop extensions and plug-ins to support all the different types of browsers. As still another example, while proxies, such as a local proxy that resides on the user's computing device or a network proxy that resides on the network, may provide controls for monitoring and managing navigation to, or access of, electronic resources, users may not want local proxies to be installed on their personal computing devices. With respect to network proxies, users may not want their personal network traffic to go through network proxies and be monitored. Moreover, the organization may not favor the use of such proxies for various reasons, including privacy and security concerns with respect to users using their personal computing devices, for example. In any such cases, an organization is unable to monitor and manage navigation to, or access of, electronic resources by users associated with the organization since the organization is out of the loop with respect to being able to apply its access policies to the access of electronic resources. Embodiments of the present disclosure provide solutions to these and other technical problems described herein.
In accordance with one example embodiment provided to illustrate the broader concepts, systems, and techniques described herein, a method may include, by a computing device, receiving input via an application of the computing device, the input to initiate navigation to a resource, and determining that navigation to the resource via the application is insecure. The method may also include, by the computing device, responsive to the determination that the navigation is insecure, modifying the navigation to the resource so as to prevent navigation to the resource via the application.
According to another illustrative embodiment provided to illustrate the broader concepts described herein, a system includes a memory and one or more processors in communication with the memory. The processor may be configured to receive input via an application of the computing device, the input to initiate navigation to a resource, and determine that navigation to the resource via the application is insecure. The processor may be further configured to, responsive to the determination that the navigation is insecure, modify the navigation to the resource so as to prevent navigation to the resource via the application.
According to another illustrative embodiment provided to illustrate the broader concepts described herein, a method may include, by a computing device, receiving an input via an application of the computing device to navigate to a resource and determining that the navigation is insecure based on a list of one or more addresses of allowable resources assigned to the computing device. The method may also include, by the computing device, responsive to the determination that the navigation is insecure, modifying the navigation to the resource so as to prevent navigation to the resource via the application.
The foregoing and other objects, features and advantages will be apparent from the following more particular description of the embodiments, as illustrated in the accompanying drawings in which like reference characters refer to the same parts throughout the different views. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the embodiments.

In cloud computing environment 300, one or more clients 102a-102n (such as those described above) are in communication with a cloud network 304. Cloud network 304 may include back-end platforms, e.g., servers, storage, server farms or data centers. The users or clients 102a-102n can correspond to a single organization/tenant or multiple organizations/tenants. More particularly, in one illustrative implementation, cloud computing environment 300 may provide a private cloud serving a single organization (e.g., enterprise cloud). In another example, cloud computing environment 300 may provide a community or public cloud serving multiple organizations/tenants.
In some embodiments, a gateway appliance(s) or service may be utilized to provide access to cloud computing resources and virtual sessions. By way of example, Citrix Gateway, provided by Citrix Systems, Inc., may be deployed on-premises or on public clouds to provide users with secure access and single sign-on to virtual, SaaS and web applications. Furthermore, to protect users from web threats, a gateway such as Citrix Secure Web Gateway may be used. Citrix Secure Web Gateway uses a cloud-based service and a local cache to check for URL reputation and category.
In still further embodiments, cloud computing environment 300 may provide a hybrid cloud that is a combination of a public cloud and a private cloud. Public clouds may include public servers that are maintained by third parties to clients 102a-102n or the enterprise/tenant. The servers may be located off-site in remote geographical locations or otherwise.
Cloud computing environment 300 can provide resource pooling to serve multiple users via clients 102a-102n through a multi-tenant environment or multi-tenant model with different physical and virtual resources dynamically assigned and reassigned responsive to different demands within the respective environment. The multi-tenant environment can include a system or architecture that can provide a single instance of software, an application or a software application to serve multiple users. In some embodiments, cloud computing environment 300 can provide on-demand self-service to unilaterally provision computing capabilities (e.g., server time, network storage) across a network for multiple clients 102a-102n. By way of example, provisioning services may be provided through a system such as Citrix Provisioning Services (Citrix PVS). Citrix PVS is a software-streaming technology that delivers patches, updates, and other configuration information to multiple virtual desktop endpoints through a shared desktop image. Cloud computing environment 300 can provide an elasticity to dynamically scale out or scale in response to different demands from one or more clients 102. In some embodiments, cloud computing environment 300 can include or provide monitoring services to monitor, control and/or generate reports corresponding to the provided shared services and resources.
In some embodiments, cloud computing environment 300 may provide cloud-based delivery of different types of cloud computing services, such as Software as a service (SaaS) 308, Platform as a Service (PaaS) 312, Infrastructure as a Service (IaaS) 316, and Desktop as a Service (DaaS) 320, for example. IaaS may refer to a user renting the use of infrastructure resources that are needed during a specified time period. IaaS providers may offer storage, networking, servers or virtualization resources from large pools, allowing the users to quickly scale up by accessing more resources as needed. Examples of IaaS include AMAZON WEB SERVICES provided by Amazon.com, Inc., of Seattle, Washington, RACKSPACE CLOUD provided by Rackspace US, Inc., of San Antonio, Texas, Google Compute Engine provided by Google Inc. of Mountain View, California, or RIGHTSCALE provided by RightScale, Inc., of Santa Barbara, California.
PaaS providers may offer functionality provided by IaaS, including, e.g., storage, networking, servers or virtualization, as well as additional resources such as, e.g., the operating system, middleware, or runtime resources. Examples of PaaS include WINDOWS AZURE provided by Microsoft Corporation of Redmond, Washington, Google App Engine provided by Google Inc., and HEROKU provided by Heroku, Inc. of San Francisco, California.
SaaS providers may offer the resources that PaaS provides, including storage, networking, servers, virtualization, operating system, middleware, or runtime resources. In some embodiments, SaaS providers may offer additional resources including, e.g., data and application resources. Examples of SaaS include GOOGLE APPS provided by Google Inc., SALESFORCE provided by Salesforce.com Inc. of San Francisco, California, or OFFICE 365 provided by Microsoft Corporation. Examples of SaaS may also include data storage providers, e.g., Citrix ShareFile from Citrix Systems, DROPBOX provided by Dropbox, Inc. of San Francisco, California, Microsoft SKYDRIVE provided by Microsoft Corporation, Google Drive provided by Google Inc., or Apple ICLOUD provided by Apple Inc. of Cupertino, California.
Similar to SaaS, DaaS (which is also known as hosted desktop services) is a form of virtual desktop infrastructure (VDI) in which virtual desktop sessions are typically delivered as a cloud service along with the apps used on the virtual desktop. Citrix Cloud from Citrix Systems is one example of a DaaS delivery platform. DaaS delivery platforms may be hosted on a public cloud computing infrastructure such as AZURE CLOUD from Microsoft Corporation of Redmond, Washington (herein “Azure”), or AMAZON WEB SERVICES provided by Amazon.com, Inc., of Seattle, Washington (herein “AWS”), for example. In the case of Citrix Cloud, Citrix Workspace app may be used as a single-entry point for bringing apps, files and desktops together (whether on-premises or in the cloud) to deliver a unified experience.
Client(s) 202 may be any type of computing devices capable of accessing resource feed(s) 406 and/or SaaS application(s) 410, and may, for example, include a variety of desktop or laptop computers, smartphones, tablets, etc. Resource feed(s) 406 may include any of numerous resource types and may be provided from any of numerous locations. In some embodiments, for example, resource feed(s) 406 may include one or more systems or services for providing virtual applications and/or desktops to client(s) 202, one or more file repositories and/or file sharing systems, one or more secure browser services, one or more access control services for SaaS applications 410, one or more management services for local applications on client(s) 202, one or more internet enabled devices or sensors, etc. Each of resource management service(s) 402, resource feed(s) 406, gateway service(s) 408, SaaS application(s) 410, and identity provider 412 may be located within an on-premises data center of an organization for which system 400 is deployed, within one or more cloud computing environments, or elsewhere.
For any of illustrated components (other than client 202) that are not based within cloud computing environment 414, cloud connectors (not shown in
As explained in more detail below, in some embodiments, resource access application 424 and associated components may provide user 426 with a personalized, all-in-one interface enabling instant and seamless access to all the user's SaaS and web applications, files, virtual Windows applications, virtual Linux applications, desktops, mobile applications, Citrix Virtual Apps and Desktops™, local applications, and other data.
When resource access application 424 is launched or otherwise accessed by user 426, client interface service 416 may send a sign-on request to identity service 418. In some embodiments, identity provider 412 may be located on the premises of the organization for which system 400 is deployed. Identity provider 412 may, for example, correspond to an on-premises Windows Active Directory. In such embodiments, identity provider 412 may be connected to the cloud-based identity service 418 using a cloud connector (not shown in
In other embodiments (not illustrated in
For each configured resource feed, resource feed service 420 may request an identity token from single sign-on service 422. Resource feed service 420 may then pass the feed-specific identity tokens it receives to the points of authentication for the respective resource feeds 406. Each resource feed 406 may then respond with a list of resources configured for the respective identity. Resource feed service 420 may then aggregate all items from the different feeds and forward them to client interface service 416, which may cause resource access application 424 to present a list of available resources on a user interface of client 202. The list of available resources may, for example, be presented on the user interface of client 202 as a set of selectable icons or other elements corresponding to accessible resources. The resources so identified may, for example, include one or more virtual applications and/or desktops (e.g., Citrix Virtual Apps and Desktops™, VMware Horizon, Microsoft RDS, etc.), one or more file repositories and/or file sharing systems (e.g., Sharefile®, one or more secure browsers, one or more internet enabled devices or sensors, one or more local applications installed on client 202, and/or one or more SaaS applications 410 to which user 426 has subscribed. The lists of local applications and SaaS applications 410 may, for example, be supplied by resource feeds 406 for respective services that manage which such applications are to be made available to user 426 via resource access application 424. Examples of SaaS applications 410 that may be managed and accessed as described herein include Microsoft Office 365 applications, SAP SaaS applications, Workday applications, etc.
For resources other than local applications and SaaS application(s) 410, upon user 426 selecting one of the listed available resources, resource access application 424 may cause client interface service 416 to forward a request for the specified resource to resource feed service 420. In response to receiving such a request, resource feed service 420 may request an identity token for the corresponding feed from single sign-on service 422. Resource feed service 420 may then pass the identity token received from single sign-on service 422 to client interface service 416 where a launch ticket for the resource may be generated and sent to resource access application 424. Upon receiving the launch ticket, resource access application 424 may initiate a secure session to gateway service 408 and present the launch ticket. When gateway service 408 is presented with the launch ticket, it may initiate a secure session to the appropriate resource feed and present the identity token to that feed to seamlessly authenticate user 426. Once the session initializes, client 202 may proceed to access the selected resource.
When user 426 selects a local application, resource access application 424 may cause the selected local application to launch on client 202. When user 426 selects SaaS application 410, resource access application 424 may cause client interface service 416 request a one-time uniform resource locator (URL) from gateway service 408 as well a preferred browser for use in accessing SaaS application 410. After gateway service 408 returns the one-time URL and identifies the preferred browser, client interface service 416 may pass that information along to resource access application 424. Client 202 may then launch the identified browser and initiate a connection to gateway service 408. Gateway service 408 may then request an assertion from single sign-on service 422. Upon receiving the assertion, gateway service 408 may cause the identified browser on client 202 to be redirected to the logon page for identified SaaS application 410 and present the assertion. The SaaS may then contact gateway service 408 to validate the assertion and authenticate user 426. Once the user has been authenticated, communication may occur directly between the identified browser and the selected SaaS application 410, thus allowing user 426 to use client 202 to access the selected SaaS application 410.
In some embodiments, the preferred browser identified by gateway service 408 may be a specialized browser embedded in resource access application 424 (when the resource application is installed on client 202) or provided by one of the resource feeds 406 (when resource access application 424 is located remotely), e.g., via a secure browser service. In such embodiments, SaaS applications 410 may incorporate enhanced security policies to enforce one or more restrictions on the embedded browser. Examples of such policies include (1) requiring use of the specialized browser and disabling use of other local browsers, (2) restricting clipboard access, e.g., by disabling cut/copy/paste operations between the application and the clipboard, (3) restricting printing, e.g., by disabling the ability to print from within the browser, (3) restricting navigation, e.g., by disabling the next and/or back browser buttons, (4) restricting downloads, e.g., by disabling the ability to download from within the SaaS application, and (5) displaying watermarks, e.g., by overlaying a screen-based watermark showing the username and IP address associated with client 202 such that the watermark will appear as displayed on the screen if the user tries to print or take a screenshot. Further, in some embodiments, when a user selects a hyperlink within a SaaS application, the specialized browser may send the URL for the link to an access control service (e.g., implemented as one of the resource feed(s) 406) for assessment of its security risk by a web filtering service. For approved URLs, the specialized browser may be permitted to access the link. For suspicious links, however, the web filtering service may have client interface service 416 send the link to a secure browser service, which may start a new virtual browser session with client 202, and thus allow the user to access the potentially harmful linked content in a safe environment.
In some embodiments, in addition to or in lieu of providing user 426 with a list of resources that are available to be accessed individually, as described above, user 426 may instead be permitted to choose to access a streamlined feed of event notifications and/or available actions that may be taken with respect to events that are automatically detected with respect to one or more of the resources. This streamlined resource activity feed, which may be customized for each user 426, may allow users to monitor important activity involving all of their resources—SaaS applications, web applications, Windows applications, Linux applications, desktops, file repositories and/or file sharing systems, and other data through a single interface, without needing to switch context from one resource to another. Further, event notifications in a resource activity feed may be accompanied by a discrete set of user-interface elements, e.g., “approve,” “deny,” and “see more detail” buttons, allowing a user to take one or more simple actions with respect to each event right within the user's feed. In some embodiments, such a streamlined, intelligent resource activity feed may be enabled by one or more micro-applications, or “microapps,” that can interface with underlying associated resources using APIs or the like. The responsive actions may be user-initiated activities that are taken within the microapps and that provide inputs to the underlying applications through the API or other interface. The actions a user performs within the microapp may, for example, be designed to address specific common problems and use cases quickly and easily, adding to increased user productivity (e.g., request personal time off, submit a help desk ticket, etc.). In some embodiments, notifications from such event-driven microapps may additionally or alternatively be pushed to clients 202 to notify user 426 of something that requires the user's attention (e.g., approval of an expense report, new course available for registration, etc.).
In some embodiments, a microapp may be a single use case made available to users to streamline functionality from complex enterprise applications. Microapps may, for example, utilize APIs available within SaaS, web, or home-grown applications allowing users to see content without needing a full launch of the application or the need to switch context. Absent such microapps, users would need to launch an application, navigate to the action they need to perform, and then perform the action. Microapps may streamline routine tasks for frequently performed actions and provide users the ability to perform actions within resource access application 424 without having to launch the native application. The system shown in
Referring to
In some embodiments, microapp service 430 may be a single-tenant service responsible for creating the microapps. Microapp service 430 may send raw events, pulled from systems of record 428, to analytics service 438 for processing. The microapp service may, for example, periodically pull active data from systems of record 428.
In some embodiments, active data cache service 436 may be single-tenant and may store all configuration information and microapp data. It may, for example, utilize a per-tenant database encryption key and per-tenant database credentials.
In some embodiments, credential wallet service 434 may store encrypted service credentials for systems of record 428 and user OAuth2 tokens.
In some embodiments, data integration provider service 432 may interact with systems of record 428 to decrypt end-user credentials and write back actions to systems of record 428 under the identity of the end-user. The write-back actions may, for example, utilize a user's actual account to ensure all actions performed are compliant with data policies of the application or other resource being interacted with.
In some embodiments, analytics service 438 may process the raw events received from microapps service 430 to create targeted scored notifications and send such notifications to notification service 440.
Finally, in some embodiments, notification service 440 may process any notifications it receives from analytics service 438. In some implementations, notification service 440 may store the notifications in a database to be later served in a notification feed. In other embodiments, notification service 440 may additionally or alternatively send the notifications out immediately to client 202 as a push notification to user 426.
In some embodiments, a process for synchronizing with systems of record 428 and generating notifications may operate as follows. Microapp service 430 may retrieve encrypted service account credentials for systems of record 428 from credential wallet service 434 and request a sync with data integration provider service 432. Data integration provider service 432 may then decrypt the service account credentials and use those credentials to retrieve data from systems of record 428. Data integration provider service 432 may then stream the retrieved data to microapp service 430. Microapp service 430 may store the received systems of record data in active data cache service 436 and also send raw events to analytics service 438. Analytics service 438 may create targeted scored notifications and send such notifications to notification service 440. Notification service 440 may store the notifications in a database to be later served in a notification feed and/or may send the notifications out immediately to client 202 as a push notification to user 426.
In some embodiments, a process for processing a user-initiated action via a microapp may operate as follows. Client 202 may receive data from microapp service 430 (via client interface service 416) to render information corresponding to the microapp. Microapp service 430 may receive data from active data cache service 436 to support that rendering. User 426 may invoke an action from the microapp, causing resource access application 424 to send that action to microapp service 430 (via client interface service 416). Microapp service 430 may then retrieve from credential wallet service 434 an encrypted Oauth2 token for the system of record for which the action is to be invoked and may send the action to data integration provider service 432 together with the encrypted Oath2 token. Data integration provider service 432 may then decrypt the Oath2 token and write the action to the appropriate system of record under the identity of user 426. Data integration provider service 432 may then read back changed data from the written-to system of record and send that changed data to microapp service 430. Microapp service 432 may then update active data cache service 436 with the updated data and cause a message to be sent to resource access application 424 (via client interface service 416) notifying user 426 that the action was successfully completed.
In some embodiments, in addition to or in lieu of the functionality described above, resource management services 402 may provide users the ability to search for relevant information across all files and applications. A simple keyword search may, for example, be used to find application resources, SaaS applications, desktops, files, etc. This functionality may enhance user productivity and efficiency as application and data sprawl is prevalent across all organizations.
In other embodiments, in addition to or in lieu of the functionality described above, resource management services 402 may enable virtual assistance functionality that allows users to remain productive and take quick actions. Users may, for example, interact with the “Virtual Assistant” and ask questions such as “What is Bob Smith's phone number?” or “What absences are pending my approval?” Resource management services 402 may, for example, parse these requests and respond because they are integrated with multiple systems on the backend. In some embodiments, users may be able to interact with the virtual assistance through either resource access application 424 or directly from another resource, such as Microsoft Teams. This feature may allow employees to work efficiently, stay organized, and deliver only the specific information they're looking for.

Client device 502 can include smartphones, tablet computers, laptop computers, desktop computers, or other computing devices configured to run user applications (or “apps”). In some embodiments, client device 502 may be substantially similar to client machine 102 described above in the context of
With continued reference to, and as shown in
Resource management services 402 may include a policy service 508. Policy service 508 can maintain policy and other configuration information related to the one or more organizations operating in network environment 500 including resource access policies defined by the organizations for enforcement within network environment 500. Via policy service 508, an organization can define one or more security policies related to users 506 and/or devices 502 associated with the organization. As shown in
An organization may also specify, via security policy 508a, a list of “managed” applications (e.g., applications that are managed and trusted by the organization) which can be used to access resources. In other words, when using a managed application, users are permitted to navigate to or otherwise access resources (both permitted resources and unpermitted resources). Then, when a user attempts to navigate to an address using a managed application, it can be determined that the initiated navigation is a secure navigation since a managed application is being utilized to navigate to the resource. Even in cases where the resource is an unpermitted resource, the navigation to the unpermitted resource can be determined to be secure since the organization's security policies can be applied to the managed application.
An organization may also specify, via security policy 508a, a list of “unmanaged” applications (e.g., applications that are not managed by resource management services 402) which cannot be used to access resources. In other words, users are not permitted to use an unmanaged application to navigate to or otherwise access resources. Then, when a user attempts to navigate to an address using an unmanaged application, a determination can be made as to whether the address is of an unpermitted resource (i.e., a resource the user is not permitted to access). If the address is of an unpermitted resource, it can be determined that the initiated navigation is an insecure navigation since an unmanaged application is being utilized to navigate to the unpermitted resource. In some such cases, the address of the unpermitted resource can be replaced with an address of a safe or secure resource, causing the application to navigate to or otherwise access the safe resource. Here, the user is directed to a different resource (i.e., a safe resource) than the resource that the user wanted to access.
In some cases, when a user attempts to navigate to an address of an unpermitted resource using an unmanaged application (i.e., the initiated navigation is an insecure navigation), a managed application can be launched, and the unpermitted resource can be opened in the managed application. Here, the unpermitted resource is opened in a managed and secure environment.
In some cases, when a user attempts to navigate to an address of an unpermitted resource using an unmanaged application (i.e., the initiated navigation is an insecure navigation), a secure browser URL (e.g., a browser managed by the organization) can be obtained with which to navigate to the unpermitted resource, a secure browser session can be launched using the secure browser URL, and the unpermitted resource can be opened using the secure browser session. In one embodiment, the secure browser session can be launched in a tab of a UI in which the unmanaged application was running. Note that launching the secure browser session in the same tab provides improved user experience as the user is already interacting with the content in that tab.
A security policy targeting a particular user or group of users may be applicable to the device/devices assigned to the user/users. As discussed in detail below, these and other types of resource access policies can be used to manage navigation to, or access of, resources. In some embodiments, policy service 508 may identify which of the policies are applicable for which users/devices and deliver applicable security policies (e.g., one or more security policies 508a) to client devices 502 within network environment 500.
For example, and according to an embodiment, user 506 may use resource access application 424 executing on client device 502 to connect to resource management services 402. When resource access application 424 connects to resource management services 402, security policy 508a may be delivered to client device 502. For example, policy service 508 may send or otherwise provide to client device 502 the security policy 508a. Security policy 508a may specify the user's resource access policies that have been defined, for example, by the user's organization, including actions that are to be performed in cases of insecure navigation to prevent the insecure navigation to the resource.
As a solution to the aforementioned and other technical problems related to insecure navigation to, or access of, resources, in some embodiments, client device 502 is programmed to or otherwise includes a navigation management module 510 that is configured to monitor and detect a user using an application executing (or running) on client device 502 to initiate navigation to, or access of, a resource, to receive (or intercept) the initiated navigation, and to determine whether the initiated navigation is insecure based on applicable resource access policies (e.g., security policy 508a). In response to a determination that the initiated navigation is insecure, navigation management module 510 may modify the initiated navigation to prevent the insecure navigation to the resource. Various types of modifications can be performed, including replacing an address of the resource with an address of a safe or secure resource and/or launching a managed application and opening the navigated to resource in the managed application, for example. In an embodiment, navigation management module 510 may be implemented as a native application on client device 502, which allows navigation management module 510 to access the underlying operating system.
In more detail, and in accordance with some embodiments of the present disclosure, navigation management module 510 may be configured to detect when a process, such as an application process, starts executing on client device 502. For example, in an implementation, navigation management module 510 may generate a hook procedure (e.g., a process and/or thread creation API hook such as a CreateProcess function on WINDOWS or fork function on Linux or MACOS) to hook or inject into and execute prior to and/or at the start of an application process as the process is initiated (launched) prior to the normal (conventional) application processing. Hooking into the application process in this manner allows navigation management module 510 to determine whether the application process is related to a managed application or an unmanaged application. As noted above, an unmanaged application may be an application that is not managed by resource management services 402 and, as such, includes applications such as native browsers and local browsers. For example, the managed applications and/or unmanaged applications may be indicated in security policy 508a. In such cases, navigation management module 510 can determine whether the application process is related to a managed application or an unmanaged application based on the information contained in security policy 508a. If the application process is related to a managed application, navigation management module 510 may determine that the initiated navigation is secure (i.e., not an insecure navigation) since the navigation is initiated via a managed application. In this case, navigation management module 510 does not initiate any further actions to prevent or otherwise interfere with the normal processing of the managed application.
If the application process is related to an unmanaged application (e.g., a native or local browser), navigation management module 510 may generate a script or function (e.g., an application foreground event listener) to listen for the unmanaged application process (i.e., the unmanaged application) becoming a foreground (or active) process, and a corresponding subroutine (e.g., application foreground event handler) that is called (or initiated) when the application foreground event occurs. Upon the unmanaged application process becoming a foreground process, the application foreground event handler may listen for the inputting of an address to access a resource using the unmanaged application. For example, the application foreground event handler may generate event listeners on user interface elements of the unmanaged application to listen for the inputting of an address and corresponding event handlers that are initiated when an address input event occurs. As another example, the application foreground event handler may generate a keyboard mouse handler to detect an enter key being pressed or a mouse/user event handler to detect a navigation control being clicked. In any case, the event handlers that are initiated when an address input event occurs may check an applicable resource access policy (e.g., security policy 508a) to the input address to determine whether the initiated navigation to the resource is an insecure navigation.
For example, in the case where the unmanaged application is a local or native browser, navigation management module 510 may generate an event handler that is initiated when the browser window is in the foreground (i.e., the browser window becomes the foreground window). In such example cases, the event handler (e.g., window foreground event handler) may generate scripts or functions (e.g., user interface element event listeners) that listen for events on user interface elements, such as a URL address bar, of the browser. For example, the window foreground event handler may generate event listeners on the URL address bar to listen for events, such as a FocusChangeEvent, and be notified when the contents (or text) in the URL address bar change. The change in the contents of the URL address bar may be indicative of an address being input to the browser. As another example, the window foreground event hander may use UI automation to access the UI element corresponding to the address bar and access its property, such as value/text, to monitor for a change in the URL address. Upon being notified of the change in the contents of the URL address bar (i.e., initiation of the event listener on the URL address bar), a corresponding event handler (e.g., URL address bar event handler) may generate a keyboard hook procedure to monitor for and detect the input of the “enter” key. Upon the input of the “enter” key, navigation management module 510 may check the address in the URL address bar (i.e., the input URL) with an applicable resource access policy (e.g., security policy 508a) to determine whether the address is of an unpermitted resource (i.e., a resource that the user is not permitted to access). If the address is of an unpermitted resource, navigation management module 510 can determine that the initiated navigation to the resource referenced by the address is an insecure navigation.
In cases where the initiated navigation to a resource is an insecure navigation, navigation management module 510 can modify the initiated navigation to prevent the insecure navigation to the resource as specified by security policy 508a, for example. As one example, upon a determination that the initiated navigation is an insecure navigation, navigation management module 510 may replace the address in the URL address bar with an address of a safe or secure resource (e.g., an address of a secure browser or a resource managed by resource management services 402) as specified in security policy 508a, for example. As another example, upon a determination that the initiated navigation is an insecure navigation, navigation management module 510 may launch a managed application as specified in security policy 508a, for example, and cause the resource referenced by the address in the URL address bar to be opened in the managed application. In some such examples, the managed application (e.g., a secure browser) can be launched in a tab of a UI in which the unmanaged application was running, and the resource referenced by the address in the URL address bar to be opened in the managed application launched in the same tab. As another example, upon a determination that the initiated navigation is an insecure navigation, navigation management module 510 may prevent navigation to the resource referenced by the address in the URL address bar by use of the local or native browser. In any such cases, navigation management module 510 may also alert or notify an analytics service and/or a user of the attempted insecure navigation.
In some embodiments, client device 502 may be configured to detect a use of a hyperlink (sometimes referred to herein more simply as a “link”) to initiate navigation to, or access of, a resource, and to receive (or intercept) the initiated navigation. Client device 502 may then determine whether the initiated navigation is insecure based on applicable resource access policies (e.g., security policy 508a), and, responsive to a determination that the initiated navigation is insecure, modify the initiated navigation to prevent the insecure navigation to the resource. Such navigation to a resource using a link may result in the resource being opened in a native or local browser, in which case the organization is out of the loop with respect to the opening of the resource and may not be able to apply its conventional security and/or access policies.
In an illustrative use case and embodiment, a user (e.g., user 506) may click, select, or otherwise activate a link within an application (e.g., a Slack client or a publishing application client), which may be a managed application or an unmanaged application, to initiate navigation to, or access of, a resource referenced by the link. To detect a use of a link to initiate navigation to, or access of, a resource, in some embodiments, navigation management module 510 may generate a hook procedure (e.g., an operating system API hook such as a CreateProcess function) to hook or inject into and execute prior to and/or at the start of a process as the process is initiated (launched) prior to normal processing of the launched process. Hooking into the launched process in this manner allows navigation management module 510 to determine whether the launched process is related to a clicking, selecting, or activation of a link. For example, the hook procedure can check the arguments that are passed with the hook procedure (e.g., arguments of the CreateProcess function) to determine whether the arguments include an address (e.g., URL) of a resource. If the launched process is not related to a clicking, selecting, or activation of a link (i.e., the arguments passed with the hook procedure do not include an address of a resource), the hook procedure may return, thus allowing normal processing of the launched process. However, if the launched process is related to a clicking, selecting, or activation of a link (i.e., the arguments passed with the hook procedure include an address of a resource), navigation management module 510 may check the address associated with the link (e.g., URL) with an applicable resource access policy (e.g., security policy 508a) to determine whether the initiated navigation to the resource is an insecure navigation. If the initiated navigation to the resource is insecure, navigation management module 510 can modify the initiated navigation to prevent the insecure navigation to the resource as specified by security policy 508a, as previously described herein, for example.
In some embodiments, navigation management module 510 may utilize optical character recognition (OCR) or other computer vision (CV) techniques to determine whether the content of an application (e.g., a managed application or an unmanaged application) contains a link. The content of the application may be in a text-based format (e.g., textual data) or an image-based format (e.g., an image of the content). In the case of an image, navigation management module 510 may utilize OCR to convert the image of the content to textual data. It will be appreciated that other methods/techniques of text extraction may also be used (e.g., textual data may be embedded in the content and extracted). In any case, navigation management module 510 may utilize OCR to scan the content to identify any links contained in the content. For example, navigation management module 510 may utilize OCR to scan the textual data for certain keywords or phrases, and/or search the textual data using regular expressions, for patterns of characters indicative of a URL to identify any links contained in the content. For the individual links that are identified, navigation management module 510 may also identify the coordinates of the text contained in the link (e.g., a URL). Having identified the link(s) contained in the content of the application, navigation management module 510 may generate user interface element event listeners/handlers and/or system/OS handlers (e.g., a mouse handler) to listen for and process a clicking or activation of the link(s) contained in the application. In an embodiment, the click event coordinates may be compared with the coordinates identified and corresponding to the text contained in the link being clicked. In such embodiments, the actual mouse click event is prevented and the text contained in the link (e.g., a URL) is instead checked against the applicable access policies and handled appropriately.
With reference to process 600 of
At 602, navigation management module 510 may detect a launch of a non-secure browser application (e.g., local or native browser or other unmanaged application). For example, navigation management module 510 may generate a hook procedure (e.g., operating system API hook) to hook into and execute at the start of a process as the process is launched prior to the normal processing of the launched process. Using the generated hook procedure, navigation management module 510 can detect a launch of a process and may determine that the launched process is related to a non-secure browser application based on the information contained in security policy 508a.
Upon determination of an initiation of a non-secure browser application process, at 604, navigation management module 510 may monitor for the non-secure browser application becoming active. For example, navigation management module 510 may generate a browser application foreground event listener to listen for the non-secure browser application becoming a foreground (active) process, and a corresponding browser application foreground event handler that is initiated (or executed) when the event (i.e., the non-secure browser application becoming a foreground process) occurs. In an example use case, user 506 may use client device 502 to launch the non-secure browser application to use in navigating to a resource.
At 606, navigation management module 510 may detect the non-secure browser application becoming a foreground (active) process. For example, the detection may be based on the initiation of the browser application foreground event handler. Continuing the above example use case, user 506 may make a window (UI) of the non-secure browser application on client device 502 an active window to input an address of a resource.
Upon detection of the non-secure browser application process becoming a foreground (active) process, at 608, navigation management module 510 may monitor for an input of an address (e.g., an address of a resource) to the non-secure browser application. For example, initiated browser application foreground event handler may generate event listeners on user interface elements of the non-secure browser application to listen for the inputting of an address, and corresponding event handlers that are initiated when an address input event occurs.
At 610, navigation management module 510 may detect an address input to the non-secure browser application. For example, the detection may be based on the initiation of a user interface element event handler. Continuing the above example use case, user 506 may input an address of a resource in a URL address bar provided in the non-secure browser application window.
Upon detection of an address input, at 612, navigation management module 510 may monitor for an input of an “enter” key. For example, the initiated event handler (e.g., the initiated user interface element event handler) may generate a keyboard hook procedure to monitor for the input of the “enter” key. At 614, navigation management module 510 may detect the input of the “enter” key. For example, using the generated keyboard hook procedure, navigation management module 510 may detect the inputting of the “enter” key to initiate navigation to an address that was previously entered. Continuing the above example use case, user 506 may press the “enter” key on a keyboard subsequent to inputting the address of the resource in the URL address bar provided in the non-secure browser application window to initiate navigation to the resource.
Upon detection of the inputting of the “enter” key, at 616, navigation management module 510 may check the input address with security policy 508a to determine whether the address is of an unpermitted resource (i.e., a resource that user 506 is not permitted to access). If the address is of an unpermitted resource, the navigation management module 510 can determine that the initiated navigation is an insecure navigation. In cases where the initiated navigation is an insecure navigation, navigation management module 510 may modify the initiated navigation to prevent the insecure navigation as specified by security policy 508a. As an example, navigation management module 510 may prevent the insecure navigation by causing the address of the unpermitted resource to be replaced with an address of a secure address as specified by security policy 508a.
Otherwise, if the address is of a resource that is not an unpermitted resource (e.g., the address is of a permitted resource), the navigation management module 510 can determine that the initiated navigation is not an insecure navigation. In cases where the initiated navigation is not an insecure navigation, navigation management module 510 does not initiate any further actions to prevent or otherwise interfere with the initiated navigation.
In some embodiments, navigation management module 510 may check a portion of the input address, such as a domain portion the address, to determine whether the address is of an unpermitted resource. By checking a portion of the input address, navigation management module 510 need not wait for the complete address to be input to the non-secure browser application and may perform the check upon the user inputting the domain portion of the address. Then, upon detection of the “enter” key, navigation management module 510 may take an appropriate action(s) based on the determination made by the keyboard hook procedure.
At 702, navigation management module 510 may monitor for the launch of process. For example, navigation management module 510 may generate a hook procedure (e.g., operating system API hook) to hook into and execute at the start of a process as the process is initiated. The generated hook procedure may be initiated upon a launch of a process on client device 502 prior to the normal processing of the launched process. As an example use case, user 506 may use client device 502 to launch a conferencing application client to use in participating in a scheduled conference session.
At 704, navigation management module 510 may detect a launch of a process and determine that the process was launched using a link. For example, navigation management module 510 may determine that the process was launched using a link based on the presence of an address (e.g., URL) in the arguments which were passed to the hook procedure. Continuing the above example use case, user 506 may click a link provided in the conferencing application client window while participating in the conference session to access a webpage.
Upon determination that the process was launched using a link, at 706, navigation management module 510 may intercept the initiated link navigation to the resource referenced by the address associated with the link. Intercepting the initiated link navigation allows navigation management module 510 to apply security policy 508a and determine whether the initiated link navigation to the resource is an insecure navigation.
To accomplish this, at 708, navigation management module 510 may check the address associated with the link with security policy 508a to determine whether the address is of an unpermitted resource (i.e., a resource that user 506 is not permitted to access). If the address is of an unpermitted resource, navigation management module 510 can determine that the initiated link navigation is an insecure navigation. In cases where the initiated link navigation is an insecure navigation, navigation management module 510 may modify the initiated link navigation to prevent the insecure navigation as specified by security policy 508a. As an example, navigation management module 510 may prevent the insecure link navigation by launching a managed application as specified by security policy 508a and causing the resource referenced by the address associated with the link (i.e., the unpermitted resource) to be opened in the launched managed application.
Otherwise, if the address is of a resource that is not an unpermitted resource (e.g., the address is of a permitted resource), navigation management module 510 can determine that the initiated link navigation is not an insecure navigation. In cases where the initiated link navigation is not an insecure navigation, navigation management module 510 does not initiate any further actions to prevent or otherwise interfere with the initiated link navigation.

As used in the present disclosure, the terms “engine” or “module” or “component” may refer to specific hardware implementations configured to perform the actions of the engine or module or component and/or software objects or software routines that may be stored on and/or executed by general purpose hardware (e.g., computer-readable media, processing devices, etc.) of the computing system. In some embodiments, the different components, modules, engines, and services described in the present disclosure may be implemented as objects or processes that execute on the computing system (e.g., as separate threads). While some of the system and methods described in the present disclosure are generally described as being implemented in software (stored on and/or executed by general purpose hardware), specific hardware implementations, firmware implements, or any combination thereof are also possible and contemplated. In this description, a “computing entity” may be any computing system as previously described in the present disclosure, or any module or combination of modulates executing on a computing system.
Terms used in the present disclosure and in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including, but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes, but is not limited to,” etc.).
Additionally, if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present.
