<p>The present invention relates to a host security device, comprising an input/output control unit which relays the data transmitted through more than one data movement path; and a security unit which performs more than one security function by monitoring the data inputted through the input / output control unit. The input / output control unit and the security unit are integrally modulated and installed on the data movement path of a security target device. Thereby, all sorts of security services are provided for the security target device, implementing a module physically combined on the data movement path of the security target device. The present invention minimizes load of the host and provides improved security, by using an independent device different from the security target device and controlling the memory installed at the security target device. Also, the invention provides security service to the security target service without the change of composition for the security target device by loading a host security device on the memory, corresponding to a standard memory, installed at the security target device.</p> |
