Method, device and system of the invention discloses a control switch isolation card, the method is applied to the system including the security hardware device, host and isolation card, control switch isolation card through the security hardware device, so that the host operation included in different network environment, security hardware device receiving host switch send the request, the handover request contains the user password and the switch port information; judging whether the user password and pre stored user passwords are the same, and according to the current switch port information records confirm the switch port switch port information is available; in the user password and the pre stored user password consistent, and corresponding to the switch port information switch port available, send commands to the isolation switch card. The invention adopts the security hardware device to control the switching process, and the security hardware device is used as a black box, which is not easy to be attacked by a Trojan horse, thereby improving the security of switching.
