An Entropy-Based Network Anomaly Detection Method
Data mining is an interdisciplinary subfield of computer science involving methods at the intersection of artificial intelligence, machine learning and statistics. One of the data mining tasks is anomaly detection which is the analysis of large quantities of data to identify items, events or observations which do not conform to an expected pattern. Anomaly detection is applicable in a variety o...
متن کاملAn Empirical Evaluation of Entropy-based Anomaly Detection
There is considerable interest in using entropy-based analysis of traffic feature distributions for anomaly detection. Entropy-based metrics are appealing since they provide more fine-grained insights into traffic structure than traditional traffic volume analysis. While previous work has demonstrated the benefits of using the entropy of different traffic distributions in isolation to detect an...
متن کاملA Network Anomaly Detection Method Based on Transduction Scheme
Network anomaly detection has been an active and difficult research topic in the field of intrusion detection for many years. Up to now, high false alarm rate, requirement of high quality data for modeling the normal patterns and the deterioration of detection rate because of some “noisy” data in the training set still make it not perform as well as expected in practice. This paper presents a n...
متن کامل3D Gabor Based Hyperspectral Anomaly Detection
Hyperspectral anomaly detection is one of the main challenging topics in both military and civilian fields. The spectral information contained in a hyperspectral cube provides a high ability for anomaly detection. In addition, the costly spatial information of adjacent pixels such as texture can also improve the discrimination between anomalous targets and background. Most studies miss the wort...
متن کاملDistributed Monitoring of Conditional Entropy for Network Anomaly Detection
Monitoring the empirical Shannon entropy of a feature in a network packet stream has previously been shown to be useful in detecting anomalies in the network traffic. Entropy is an information-theoretic statistic that measures the variability of the feature under consideration. Anomalous activity in network traffic can be captured by detecting changes in this variability. There are several chal...
