【摘要】 提出了一种基于时间场景识别的安全报警熔合算法。该算法将已知的攻击模式定义成时间场景模型来处理在线或离线的报警流。算法同时完成报警聚合以及报警关联两个工作,并且采用基于时间推理的方法来预处理场景模型,从而使识别过程具有较高的效率。更多还原

【Abstract】 A security alert fusion algorithm based on temporal scenario recognition is proposed. Known attack patterns are defined into temporal scenario models to process online or offline alert flow. Alert aggregation and alert correlation are performed simultaneously in the recognition procedure. Methods based on temporal reasoning are adopted to preprocess temporal scenario models, giving the recognition algorithm a high efficiency.更多还原
