    • Artificial Immune Systems (AIS) including the Dendritic Cell Algorithm (DCA) are an emerging method to detect malware in computer systems. A DCA module may receive an output or signal from multiple indicators concerning the state of at least a portion of the system. The DCA module is configured to combine the plurality of signals into a single signal vector. The DCA module may be configured to sort the received signals based on signal type and magnitude of each signal. The DCA module may then use a decay factor to weight the received signals so that a large number of “nominal” signals do not drown out a small number of “strong” signals indicating a malware attack. The decay factor may be exponentially increased each time it is applied so that all received signals are considered by the DCA module, but so that the “nominal” signals may have a minimal effect.
    • 包括树突细胞算法(DCA)在内的人造免疫系统(AIS)是检测计算机系统中恶意软件的新兴方法。 DCA模块可以从关于系统的至少一部分的状态的多个指示器接收输出或信号。 DCA模块被配置为将多个信号组合成单个信号向量。 DCA模块可以被配置为基于每个信号的信号类型和幅度对接收到的信号进行分类。 然后,DCA模块可以使用衰减因子对接收的信号进行加权,使得大量的“标称”信号不会淹没少量指示恶意软件攻击的“强”信号。 衰减因子可以在每次应用时指数地增加,使得所有接收的信号都被DCA模块考虑,而是使得“标称”信号可能具有最小的影响。
