Abstract: An apparatus for LAN booting environment-based file security and centralization, a method therefor, and a computer-readable recording medium recorded with a program for performing the method are proposed. The apparatus can include a central server including a storage module for storing a plurality of operating system images; a communication module for communicating with a user device; and a LAN booting management module configured to, when receiving a LAN booting start request message from the user device through the communication module, select an operating system image that can be used in the user device among the plurality of operating systems according to user device information, and transmit the selected operating system image, a user apparatus corresponding to the same, a method for LAN booting environment-based file security and centralization of these devices, and a computer-readable recording medium recorded with a program for performing the method.
Abstract: An apparatus for selecting a representative token of the present invention includes a token graph generation unit configured to extract a plurality of tokens from a plurality of detection names for malicious files and generate a detection name token graph representing a relationship between the extracted plurality of tokens, and a representative token selection unit configured to select a representative detection name token for the input file based on the detection name token graph.
