• Title: OutCenTR: A novel semi-supervised framework for predicting exploits of vulnerabilities in high-dimensional datasets
• Authors: Hadi Eskandari, Michael Bewong, Sabih ur Rehman
• Abstract summary: We make use of outlier detection techniques to predict vulnerabilities that are likely to be exploited. We propose a dimensionality reduction technique, OutCenTR, that enhances the baseline outlier detection models. The results of our experiments show on average a 5-fold improvement of F1 score in comparison with state-of-the-art dimensionality reduction techniques.

• Abstract: An ever-growing number of vulnerabilities are reported every day. Yet these vulnerabilities are not all the same; Some are more targeted than others. Correctly estimating the likelihood of a vulnerability being exploited is a critical task for system administrators. This aids the system administrators in prioritizing and patching the right vulnerabilities. Our work makes use of outlier detection techniques to predict vulnerabilities that are likely to be exploited in highly imbalanced and high-dimensional datasets such as the National Vulnerability Database. We propose a dimensionality reduction technique, OutCenTR, that enhances the baseline outlier detection models. We further demonstrate the effectiveness and efficiency of OutCenTR empirically with 4 benchmark and 12 synthetic datasets. The results of our experiments show on average a 5-fold improvement of F1 score in comparison with state-of-the-art dimensionality reduction techniques such as PCA and GRP.

• Enhancing Code Vulnerability Detection via Vulnerability-Preserving Data Augmentation [29.72520866016839]
  Source code vulnerability detection aims to identify inherent vulnerabilities to safeguard software systems from potential attacks. Many prior studies overlook diverse vulnerability characteristics, simplifying the problem into a binary (0-1) classification task. FGVulDet employs multiple classifiers to discern characteristics of various vulnerability types and combines their outputs to identify the specific type of vulnerability. FGVulDet is trained on a large-scale dataset from GitHub, encompassing five different types of vulnerabilities.
