Feature Selection for Malware Detection on the Android Platform Based on Differences of IDF Values
(SCIENCE PRESS, 2020) Gokcer Peynirci; Mete Eminagaoglu; Korhan Karabulut; Eminagaoglu, Mete; Peynirci, Gokcer; Karabulut, Korhan
Android is the mobile operating system most frequently targeted by malware in the smartphone ecosystem with a market share significantly higher than its competitors and a much larger total number of applications. Detection of malware before being published on official or unofficial application markets is critically important due to the typical end users' widespread security inadequacy. In this paper a novel feature selection method is proposed along with an Android malware detection approach. The feature selection method proposed in this study makes use of permissions API calls and strings as features which are statically extractable from the Android executables (APK files) and it can be used in a machine learning process with different algorithms to detect malware on the Android platform. A novel document frequencybased approach namely Delta IDF was designed and implemented for feature selection. Delta IDF was tested upon three universal benchmark datasets that contain Android malware samples and highly promising results were obtained by using several binary classification algorithms.

Implementation and comparison of machine learning classifiers for information security risk analysis of a human resources department
(2010) Mete Eminaǧaoǧlu; Şaban Eren; Eminagaoglu, Mete; Eren, Saban
The aim of this study is threefold. First a qualitative information security risk survey is implemented in human resources department of a logistics company. Second a machine learning risk classification and prediction model with proper data set is established from the results obtained in this survey. Third several classifier algorithms are tested where their training and test performances are compared using error rates ROC curves Kappa statistics and F-measures. The results show that some classifier algorithms can be used to estimate specific human based information security risks within acceptable error rates. ©2010 IEEE. © 2011 Elsevier B.V.
