1. A method of intrusion detection with respect to each of a plurality of operating systems in a terminal device that supports driving of the plurality of operating systems, the method comprising:

  • collecting, at a first operating system of the plurality of operating systems in the terminal device, intrusion detection data from at least a second operating system of the plurality of operating systems in the terminal device;

    performing, at the first operating system in the terminal device, an intrusion detection with respect to the at least a second operating system in the terminal device using the collected intrusion detection data;

    performing a selective approach control with respect to the at least a second operating system of the plurality of operating systems which are simultaneously driven in the terminal device, based on a result of the performing the intrusion detection; and

    selectively restoring damaged data in the at least a second operating system based on a result of the performing the intrusion detection,wherein the performing the intrusion detection comprises analyzing the collected intrusion data and determining whether there is an intrusion in the at least a second operating system,wherein the performing the selective approach control comprises controlling of a ratio of using a central processing unit or memory of the terminal device, by the at least a second operating system into which intrusion is determined to have occurred among the plurality of operating systems which are simultaneously driven in the terminal device, andwherein the selectively restoring comprises receiving back-up data for restoring damaged data in the at least a second operating system from a server and restoring the damaged data with the back-up data, wherein the back-up data is received by the server at a predetermined interval from the terminal device and the data is data used in the at least a second operating system or image data generated with respect to the at least a second operating system.
