摘要: High speed of processing massive audit data is crucial for an anomaly Intrusion Detection System (IDS) to achieve real-time performance during the detection. Abstracting a potential solution improve efficiency processing. In this work, we propose two strategies abstraction in order build lightweight detection model. The first strategy exemplar extraction and second attribute abstraction. Two clustering algorithms, Affinity Propagation (AP) as well traditional k-means, are employed extract exemplars, Principal Component Analysis (PCA) abstract important attributes (a.k.a. features) from data. Real HTTP traffic collected our institute KDD 1999 used validate extensive test results show that process significantly improves has better than PCA
