摘要： An apparatus and method for detecting forgery/falsification of a homepage. The apparatus includes a homepage image shot generation module for generating homepage image shots of an entire screen of an accessed homepage. A character string extraction module extracts character strings from each homepage image shot using an OCR technique. A character string comparison module compares each of the extracted character strings with character strings required for determination of homepage forgery/falsification, thus determining whether the extracted character string is a normal character string or a falsified character string. A homepage falsification determination module determines whether the corresponding homepage has been forged/falsified, based on results of the comparison. A character string learning module learns the character string extracted from the homepage image shot, based on results of the determination, and classifies the character string as the normal character string or the falsified character string.

摘要： Disclosed herein is an Intrusion Detection System (IDS) false positive detection apparatus and method. An IDS false positive detection apparatus includes a payload extraction unit for extracting payloads by dividing each packet corresponding to an IDS detection rule into a header and a payload. A false positive payload information generation unit generates false positive payload information required to identify a false positive payload by extracting a payload of a false positive packet based on results of packet analysis received from a manager. A false positive payload determination unit transmits results of a determination of whether each payload extracted by the payload extraction unit corresponds to a false positive payload, based on the false positive payload information, to the manager.
摘要翻译：本文公开了入侵检测系统（IDS）假阳性检测装置和方法。 IDS假阳性检测装置包括有效载荷提取单元，用于通过将对应于IDS检测规则的每个分组划分成报头和有效载荷来提取有效载荷。假正负载信息生成单元基于从管理器接收到的分组结果的结果，提取伪阳性分组的有效载荷，生成用于识别假正负载所需的假正负载信息。假正负载确定单元向管理者发送确定由有效载荷提取单元提取的每个有效载荷是否基于假正负载信息对应于假正有效载荷的结果。

摘要： An apparatus for improving detection performance of an intrusion detection system includes a transformed detected data generation unit for changing original detected data, detected based on current detection rules, to transformed detected data complying with transformed detected data standard. A transformed detected data classification unit classifies the transformed detected data by attack type, classifies transformed detected data for attack types by current detection rule, and classifies transformed detected data for detection rules into true positives/false positives. A transformed keyword tree generation unit generates a true positive transformed keyword tree and a false positive transformed keyword tree. A true positive path identification unit generates a true positive node, and identifies a true positive path connecting a base node to the true positive node in the true positive transformed keyword tree. A true positive detection pattern generation unit generates a true positive detection pattern based on the true positive path.
