The main objective of our work is to aid in the improvement of attack detection capabilities of machine learning based network anomaly detection. The paper leverages several techniques aimed at obfuscation of remote attacks which are based on the modification of various properties of network flows. We present a tool, based on NetEm utility and Metasploit framework, which serves for automatic exploitation of network vulnerabilities enabling utilization of obfuscation techniques. The tool is applied to the chosen set of network attacks and later we use captured data for data mining experiments employing anomaly detection features called Advanced Security Network Metrics which were designed in our previous work. Experiments confirm the assumption of achieving a better classification recall and precision only in the case of obfuscated attacks are included into a training process of the Naive Bayes classifier compared to training without prior knowledge about them. We perform accuracy evaluation of all suggested obfuscations, whereby the most successful ones are based on combinations of several techniques and damaging of packets. Experimentally, our approach does not consider a normalizer of network traffic, as there were described performance and platform dependence issues with normalizers as well as differences and problems with various implementations.
