| 摘 要： | 面向入侵容忍的入侵检测是网络安全最前沿的研究热点之一．受容侵服务对象本身固有缺陷及系统噪声数据的干扰，传统异常检测算法在容侵系统中检测入侵的准确度不高且耗时较长，影响了容侵系统性能，不再适用．在分析容侵系统特性和现有异常检测方法的基础上，结合数据抗噪思想，提出了一种基于数值序列统计分析的容侵异常检测算法．理论上对算法时间复杂度的分析和真实数据集上的实验结果均表明该算法是可行高效的．

| Abstract: | Intrusion-tolerant intrusion detection has become another pivotal techniques in network security. In a noisy environment, an observation may not accurately reflect the underlying intrusion, and this would depress the intrusion-tolerant ability of system. In this paper, we provide a probabilistic connection from the observation to the underlying true value, and present a novel numerical sequence analysis-based anomaly detection algorithm for intrusion tolerance system (ITS). Finally the theoretical analysis and empirical results demonstrate the robustness and efficiency of the algorithm. |
