Abstract

Identifying an operating system running on a computer system. In one aspect of the invention, an enumeration pattern is collected, the enumeration pattern describing an enumeration of a device that has been performed between the device and the operating system running on a host computer system. The type of the operating system running on the host computer system is identified based on the collected enumeration pattern.

Claims

1. A method for identifying an operating system running on a computer, the method comprising:

collecting an enumeration pattern describing an enumeration of a device that has been performed between the device and the operating system running on a host computer system, wherein the enumeration pattern does not explicitly identify the operating system; and

identifying the type of the operating system running on the host computer system based on the collected enumeration pattern;

wherein identifying the type of the operating system is based on a comparison of the collected enumeration pattern with at least one known enumeration patterns associated with different types of operating systems;

wherein the comparison of the collected enumeration pattern with known enumeration patterns includes comparing a plurality of steps of the collected enumeration pattern to a plurality of steps in the known enumeration patterns, such that the known enumeration pattern having the highest correlation of steps to the collected enumeration pattern is selected for identifying the type of operating system.

2. The method of claim 1 wherein identifying the type of the operating system includes inputting the collected enumeration pattern to a neural network that has been trained with known enumeration patterns associated with different types of operating systems.

3. The method of claim 1 wherein the enumeration includes the host computer system requesting and receiving enumeration information from the device and providing commands to the device.

4. The method of claim 1 wherein the enumeration pattern is collected from a virtual device engine that emulates the operation of the device to at least one host computer system.

5. The method of claim 4 wherein the virtual device engine is operative to receive information from at least one additional host computer system connected to the device.

6. The method of claim 5 wherein the operating system identification and virtual device engine are provided in a management module operative to receive information from a plurality of host computer systems and connected to a plurality of devices.

7. The method of claim 1 wherein the device communicates with the host computer using one of the standard protocols including USB, SCSI, and IDE.

8. The method of claim 1 wherein the identifying the type of the operating system includes identifying a version of the operating system.

9. The method of claim 1 wherein the device is a USB device and wherein the host computer system includes a USB host controller.

10. The method of claim 1 wherein identifying the type of the operating system is based on a comparison of the collected enumeration pattern with at least one known enumeration pattern associated with a particular type of operating system.

11. The method of claim 1 wherein for each step in a sequence in the collected enumeration pattern, the step is compared to a step in an equivalent place to the step in a sequence in the known enumeration patterns.
