Patent attributes
A method adapts network intrusion detection. The method includes: a) deploying a network traffic capture system and collecting network packet traces; b) using a network audit tool, extracting features from the collected network packet traces; c) feeding the extracted features as unlabeled data into a representation function, and, utilizing the representation function as an unsupervised feature learning algorithm, learning a new representation of the unlabeled data; d) providing a labeled training set capturing examples of malicious network traffic, and, using the learned new representation of the unlabeled data, modifying the labeled training set to obtain a new training set; and e) using the new training set, training a traffic classification machine learning model.
