Method and apparatus for monitoring and filtering universal serial bus network traffic

摘要

In one embodiment, a method includes obtaining at least one packet from a first element on a Universal Serial Bus (USB) bus. The at least one packet is intended for a second element. The method also includes processing the at least one packet to determine whether the at least one packet is associated with unsafe content, and providing the at least one packet to the second element if it is determined that the at least one packet is not associated with the unsafe content. The at least one packet is provided to the second element on the USB bus. Finally, the method includes blocking the at least one packet from being provided to the second element when it is determined that the at least one packet is associated with the unsafe content.

1. A method comprising:
obtaining, at a hub device, at least one packet from a first element, the at least one packet being obtained on a Universal Serial Bus (USB) bus, wherein the at least one packet is intended for a second element; processing, at the hub device, the at least one packet to determine whether the at least one packet is associated with unsafe content; providing the at least one packet from the hub device to a processing arrangement of the second element if it is determined that the at least one packet is not associated with the unsafe content, wherein the at least one packet is provided to the second element on the USB bus; blocking the at least one packet from being provided to the processing arrangement of the second element when it is determined that the at least one packet is associated with the unsafe content; and providing an indication to the second element when it is determined that the at least one packet is associated with the unsafe content, wherein the indication is arranged to indicate that the first element is attempting to provide the unsafe content to the second element.
