Patent
Citrix Systems | Date: 2017-03-08

Methods and systems are disclosed for providing approaches to authenticating and authorizing client devices in enterprise systems via a gateway device. The methods and systems may include passing, by a computing device to an enterprise device, a request transmitted by a client device for access to an enterprise resource, and transmitting, by the computing device, authentication credentials associated with the client device with a request for authorization information associated with the enterprise resource. The methods and systems may also include receiving, by the computing device, the authorization information associated with the enterprise resource, transmitting, by the computing device, the request transmitted by the client device for access to the enterprise resource with the received authorization information associated with the enterprise resource, and passing, by the computing device to the client device, information associated with the requested enterprise resource based on the received authorization information associated with the enterprise resource.

Methods and systems for preventing clock rollback attacks are described herein. A rollback attack may occur when a user manually sets a system clock to a date/time earlier than the actual present day date and time, thereby tricking any software relying on the system clock to believe it is in fact the earlier date and time rather than the current date and time. According to aspects described herein, a particular application may check and store a record of the system time when an application goes inactive (or at intervals) and again when the application subsequently is activated again. When the application determines that the time has gone backward, the application (or system) may take some remedial measure(s) to prevent further use of the application (or system) until the user reestablishes trust (e.g., by reauthenticating or reestablishing a connection with a trusted time server).

A technique enables a user to participate in an online meeting. The technique involves receiving, by processing circuitry of a vehicle, a join instruction to join the online meeting. The technique further involves performing, by the processing circuitry of the vehicle, a communications exchange with a remote online meeting server in response to the join instruction, the communications exchange establishing an online meeting session with the remote online meeting server to join the processing circuitry of the vehicle to the online meeting. The technique further involves outputting, after the online meeting session is established and by the processing circuitry of the vehicle, video of the online meeting on a display screen which is integrated with the vehicle. Along these lines, the display screen can output a static image while the vehicle is moving and moving video while the vehicle is not moving (e.g., parked).

Methods and systems for configuring mobile applications for managed execution are described herein. Executable application binaries may each be converted into a corresponding dynamic library. The dynamic libraries may be bundled with a managing application that is configured to manage execution of the dynamic libraries at a mobile computing device. Resource files consumed by the application binary may also be bundled with the managing application and accessible to the dynamic libraries during execution. The managing application may provide a workspace within which operation of the dynamic library occurs. Operation of the dynamic library may at least partially correspond to operation of the executable application binary. Execution of the dynamic library may be bound to a process that is executed for the managing application at a processor of a computing device.


The present application is directed to methods and systems for redirecting write requests issued by trusted applications to a secure storage. Upon redirecting the write requests, the data included in those requests can be stored in the secure storage area of a client computer. In some embodiments, the methods and systems can include determining whether an application issuing the request is a trusted application that requires data to be stored in a secure storage repository. Upon making this determination, a filter driver can identify a secure storage area on a client computer and can redirect the write request to this secure storage. In other embodiments, the filter driver may deny requests of trusted applications to write to unsecure storage areas.

One or more aspects of this disclosure may relate to using a configurable server farm preference for an application, desktop or other hosted resource. Additional aspects may relate to moving server farm workloads based on the configurable server farm preference. Further aspects may relate to performing reboot cycles, a reboot schedule and on-demand rebooting. Yet further aspects may relate to staggering individual machine reboot operations over a specified period of time and performing reboot operations such that some machines are available for user sessions during a reboot cycle.

The present disclosure is directed to systems and methods for controlling delivery of a resource. An intermediary device may establish a connection to deliver a resource hosted on at least one server to a client using a remoting protocol. The remoting protocol may define one or more channels in the connection for delivering or enabling one or more features of the resource to the client. The device may identify the one or more channels, and may identify the one or more features of the resource. The device may determine a policy for controlling access of the client to at least a first feature of the resource. The device may control access of the client to the first feature by modifying a first channel of the one or more channels according to the determined policy.

The present disclosure is directed towards systems and methods for measuring round trip time (RTT) in network devices between the device and an endpoint. A network device may be deployed as an intermediary to provide many security and visibility functions. For measuring the server side RTT between the network device and host, the intermediary device identifies the packet that has been sent by the client when it initiated the RTT measurement. The network device remembers the moment T1 when it sees this packet. The host (e.g., the server) will respond to this with a packet that contains the response. The intermediary device remembers the moment T2 when it sees this response. Server side RTT is calculated by the network device as T2T1. For measuring the client side RTT the network device and client, the intermediary device identifies the packet that the host sends to initiate measurement of RTT. As per the HDX protocol, the client will respond immediately with a new packet or with a bit set in any packet being sent to the host. Just as for server side RTT, the intermediary device can identify these packets and measure the times to calculate the client side RTT.


A client computer requests a resource from an ISP/OSP. The ISP/OSP maintains multiple instances of the resource. In deciding to which instance of the resource to route the client computer, a resource selection server takes network routability information into account. Geographic proximity, resource utilization, network utilization, and/or maintenance of peering agreements may also be taken into account in selecting the instance of the resource.
