Meanwhile, the lock unit 100 and the key unit 200 according to the embodiment of the present invention serve as physical security means for the USB port 10. [ However, it is necessary to prepare for the case where the lock unit 100 is taken out of the stolen key unit 200 or the lock unit 100 is taken out in an unexpected way and is connected to the USB port 10 without permission.

To cope with such a problem, it is desirable to construct a computer security system in a manner as shown in Fig. That is, a predetermined electronic circuit 160 is mounted on the lock unit 100, a USB security program capable of performing communication with the electronic circuit 160 is installed in the computer 300, (400) through a communication network.

At this time, the USB security program of the computer 300 may include the lock monitoring means 310 and the authentication means 320. The lock monitoring means 310 displays predetermined information on the display of the computer 300 or transmits the information to the administrator terminal 400 when it is determined that the lock unit 100 has been removed from the USB port. Accordingly, the administrator can confirm in real time which computer the lock unit 100 has been removed through the display connected to the administrator terminal 400 or a predetermined warning sound.

The method of confirming whether or not the lock unit 100 is detachably attached is not particularly limited. For example, it is possible to confirm whether the electronic circuit 160 is mounted or not by communicating with the USB security program with the electronic circuit 160 provided in the lock unit 100, or whether the electronic circuit 160 is recognized by the USB hub controller of the computer 30 .

The authentication means 320 verifies whether or not the lock unit 100 distributed by a legitimate administrator has been mounted against the information stored in the semiconductor chip included in the electronic circuit 160 (e.g., product information, seller information, etc.) When the unlocking unit 100 is unauthorized, the administrator terminal 400 can transmit the corresponding information.

When the lock monitoring unit 310 determines that the lock unit 100 is disconnected or the authentication unit 320 does not approve the authentication, the USB security program restricts the operation of the computer 300 to a predetermined range The power can be turned off. As an example, input from a mouse or a keyboard connected to the computer 300 may be blocked and a predetermined message may be displayed on the screen.

As described above, the present invention is not limited to the above-described embodiments and can be modified or modified in various forms. Even if the modified or modified embodiment includes the technical idea of the present invention disclosed in the claims, Of course.
