Abstract: Proposed is a method for tracking a cyber-attack to be performed by a cyber-attack tracking device including a memory and a processor. The method may include determining a plurality of behavior events performed by network devices in one or more domains, and mapping the plurality of the behavior events onto metadata of preset standards. The method may also include generating relationship data indicating a relationship between behavior events mapped onto metadata designated as a preset group based on the metadata mapped onto the behavior events. The method may further include counting a number of behavior events related to a preset suspected behavior among behavior events having a relationship data same as a relationship data of a first behavior event to calculate score for the relationship data including the first behavior event.

Abstract: A method of determining topographical interference with a guided missile is proposed. The method may include obtaining a pre-calculated expected trajectory of a guided missile. The method may also include extracting topographic elevations with respect to a topography corresponding to the pre-calculated expected trajectory from stored topographical information. The method may further include determining presence or absence of topographical interference with the guided missile based on bottom trajectory elevation values in the pre-calculated expected trajectory and topographic elevation values corresponding to the bottom trajectory elevation values. The pre-calculated expected trajectory may include top, bottom, left, and right trajectories with respect to a launch direction of the guided missile, calculated based on an error factor for the guided missile, and the error factor includes manufacturing error values with respect to at least one of a weight, center of gravity, a thrust, or a moment of inertia of the guided missile.
