Abstract

A processing device receives, from a remote access client executing on a mobile device, user input provided in a portion of an application window being displayed on the mobile device. The application window on the mobile device corresponds to an application executing on a remote host. The user input requests an operation to be performed on the application window and specifies a location of the portion of the application window in which the user input was provided. The processing device determines whether the portion of the application window is a restricted portion with respect to the requested operation to be performed on the application window, and prevents the remote access client on the mobile device from performing the requested operation responsive to a determination that the portion of the application window is the restricted portion.

3. The method of claim 1, wherein the requested operation is associated with a plurality of commands, and wherein preventing the remote access client on the mobile device from performing the requested operation comprises:

sending, by the processor of the remote host, a first command of the plurality of commands to the application executing on the remote host; and

ignoring, by the processor of the remote host, other commands of the plurality of commands.

4. The method of claim 1, wherein the location comprises coordinates of the portion of the application window.

5. The method of claim 1, wherein determining whether the portion of the application window is the restricted portion comprises:

sending the location of the portion of the application window to an operating system of the remote host to determine whether the location corresponds to any user interface (UI) element from a stored list of restricted UI elements; and

receiving a response from the operating system indicating that the location corresponds to a UI element from the stored list of restricted UI elements.

6. The method of claim 5, wherein the UI element is at least one of a title bar, a tool bar, a status bar, or a resize handle.

7. The method of claim 1, wherein determining whether the portion of the application window is the restricted portion comprises:

sending the location of the portion of the application window to an operating system of the remote host to determine whether the location corresponds to any user interface (UI) element from a stored list of restricted UI elements;

receiving a response from the operating system indicating that the location does not correspond to any UI element from the stored list of restricted UI elements;

comparing the location to application data specifying restricted areas in the application window; and

determining, based on the comparison, that the location corresponds to one of the specified restricted areas.

8. The method of claim 1, wherein determining whether the portion of the application window is the restricted portion comprises:

querying an operating system of the remote host to obtain an element identifier and an application identifier; and

determining whether the portion of the application window is the restricted portion based on at least one of the element identifier or the application identifier.

9. The method of claim 1, further comprising:

allowing, by the processor of the remote host, the remote access client on the mobile device to perform the requested operation responsive to a determination that the portion of the application window is not the restricted portion.

10. The method of claim 9, wherein allowing the remote access client to perform the request operation comprise:

sending a plurality of commands associated with the requested operation to the application being executed on the remote host.

11. The method of claim 1, wherein a user of the mobile device is validated to the remote host.

12. The method of claim 1, wherein the mobile device and the remote host are connected through a proxy server-based broker over a proxy broker connection.

13. The method of claim 12, wherein the proxy server-based broker is a closest proxy server-based broker to the remote host.

14. The method of claim 1, wherein the user input is provided via a cursor control device of the mobile device, a keyboard of the mobile device, or one or more touches on a screen of the mobile device.
