In this particular research work, the efficacy of directionality properties for classification is explored, through engineered features from those on existing datasets. This study curates two datasets, Dataset A which includes features extracted from only single directional packet flows and Dataset B which includes those from bi-directional packet flows. Classification with these features is performed with selected classifiers, where SVM obtained the highest accuracy with 99.88% for Dataset A, while the highest accuracy went to RF, DT and XGBoost for Dataset B with 99.24%. Comparing these results with those from existing research work, the directional properties in these engineered features are able to provide improvements in terms of accuracy in classifying these spywares.
