Using RS and SVM to Detect New Malicious Executable Codes

A hybrid algorithm based on attribute reduction of Rough Sets(RS) and classification principles of Support Vector Machine (SVM) to detect new malicious executable codes is present. Firstly, the attribute reduction of RS has been applied as preprocessor so that we can delete redundant attributes and conflicting objects from decision making table but remain efficient information lossless. Then, we realize classification modeling and forecasting test based on SVM. By this method, we can reduce the dimension of data, decrease the complexity in the process. Finally, comparison of detection ability between the above detection method and others is given. Experiment result shows that the present method could effectively use to discriminate normal and abnormal executable codes.
