A method for keyboard security and a recording medium storing a keyboard security driver using the same are provided to block malicious keyboard data leakage by modifying a call function of an IRP(I/O(Input/Output) Request Packet) dispatch table of a USB(Universal Serial Bus) hub driver, which is the bottom layer of a system. A call function for IRP_ML_INTERNAL_DEVICE_CONTROL among an IRP dispatch table of a USB hub driver is changed into a security device control function(S534). The call functions for a keyboard disconnection request IRP among the IRP dispatch table of the USB hub driver are changed into a security device disconnection function. Device objects to protect inputted data are registered to a protected device list database. It is continuously monitored whether contents of the IRP dispatch table of the USB hub driver are changed. First and second stages are repeated when the contents of the IRP dispatch table of the USB hub driver are changed.
