    • An apparatus and a method for detecting a malicious program by using behavior of a computer are provided to generates optimized malicious code diagnosis data which are used for judging whether a computer program executed in a computer system is a normal code or a malicious code. A behavior feature vector creation unit(410) creates a first behavior feature vector based on behavior features extracted from a diagnosis target program, and a diagnosis data storage unit(420) stores plural second behavior feature vectors for a sample program of which malicious feature is known to everybody. A code diagnosis unit(430) diagnoses whether or not a diagnosis target program is a malicious code by comparing the first behavior feature vector with the plural behavior feature vectors, and the code diagnosis unit consists of a distance calculation unit(440) and a code judgment unit(450).
    • 提供了一种通过使用计算机的行为来检测恶意程序的装置和方法,用于产生用于判断在计算机系统中执行的计算机程序是正常代码还是恶意代码的优化恶意代码诊断数据。 行为特征向量创建单元(410)基于从诊断目标程序提取的行为特征创建第一行为特征向量,并且诊断数据存储单元(420)存储用于其恶意特征的样本程序的多个第二行为特征向量 众所周知 代码诊断单元(430)通过将第一行为特征向量与多个行为特征向量进行比较来诊断诊断目标程序是否是恶意代码,并且代码诊断单元由距离计算单元(440)和代码 判断单元(450)。
