Abstract:
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; and performing a selective approach control with respect to the at least a second operating system of the plurality of operating systems 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 first operating system is configured not to be connected to a network of an external device, 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.
