Abstract
A removable drive is plug compatible with a host computer preferably through its USB port. The drive auto-launches upon insertion and runs read, write and execute functions on a resident file in the removable drive, tagging the control programs of the host computer that are responsible for these functions. The control programs are then copied to the removable drive and the path for these functions is changed to the removable drive. When the removable drive is right protected, the host computer is no longer a viable target for unauthorized access.
Claims13
A method for protecting a host computer, the method comprising the steps of:
- interconnecting the host computer with a memory device having a memory space containing an executable program;
- configuring the memory device with a physical switch having a first state enabling signal flow from the host computer to the memory device and a second state disabling signal flow from the host computer to the memory device;
- placing the physical switch in the first state;
- loading the executable program onto the host computer;
- executing a write function in the host computer;
- flagging control files of the host computer that are used in execution of the write function;
- copying the flagged write control files into the memory space of the memory device;
- executing a change-path function in the host computer to point to the copies of the control files in the memory device;
- and placing the physical switch into the second state for write protecting the memory device.
A method for protecting a host computer comprising the steps of:
- incorporating a memory device within the host computer, the memory device having a memory space containing an executable program;
- configuring the memory device with a physical switch having a first state enabling signal flow from the host computer to the memory device and a second state disabling signal flow from the host computer to the memory device;
- placing the physical switch in the first state;
- loading the executable program onto the host computer;
- executing a write function in the host computer;
- flagging control files of the host computer that are used in execution of the write function;
- copying the flagged write control files into the memory space of the memory device;
- executing a change-path function in the host computer to point to the copies of the control files in the memory device;
- and placing the physical switch into the second state for write protecting the memory device.
A method for protecting a host computer operating system for unwanted modifications, the method comprising the steps of:
- copying control files of the operating system to an interconnected memory device having a physical switch activated write protection mode;
- and directing paths for executable control functions to the memory device;
- and placing the physical switch into a mode for write protecting the memory device.
