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.
