Abstract

The increasing use of Virtual Private Networks (VPNs) in modern networks poses significant challenges for network monitoring and traffic management, particularly in accurately and efficiently distinguishing VPN and non-VPN traffic. This study aims to analyze the effectiveness of the SelectKBest feature selection method in improving VPN traffic classification performance using Random Forest and Support Vector Machine (SVM) algorithms. The dataset used in this study is the CIC VPN-NonVPN Traffic Dataset provided by the Canadian Institute for Cybersecurity (CIC), which is widely recognized as a standard benchmark in network security research. Feature selection was performed using SelectKBest with the ANOVA (f_classif) scoring function, reducing the original feature set to 15 most relevant features. Experimental results show that the Random Forest classifier achieved a test accuracy of 84.94%, along with high F1-score and ROC-AUC values, and an average cross-validation accuracy of 95.18% with low variance. In contrast, the SVM model demonstrated relatively poor performance, with a test accuracy of approximately 62%, indicating its limitation in capturing the complex patterns of network traffic data. Further analysis using ROC curves, Precision–Recall curves, confusion matrices, and learning curves confirms that Random Forest exhibits superior generalization capability compared to SVM. These findings indicate that the combination of SelectKBest and Random Forest not only delivers high classification performance but also improves computational efficiency through feature dimensionality reduction, making it suitable for large-scale VPN traffic classification scenarios.

Abstract

This study aims to analyze the forms of legal protection for honorary teachers within the Cianjur Regency Education Office and to identify various obstacles in their implementation. Honorary teachers play a strategic role in the provision of education; however, they are often in a vulnerable position due to uncertain employment status, low welfare, and limited legal protection guarantees. This research employs a normative legal research method using a statutory approach and a conceptual approach. The legal materials used consist of primary legal materials in the form of laws and regulations related to labor, education, and the state civil apparatus, as well as secondary legal materials such as literature, journals, and relevant research findings. The results of the study indicate that legal protection for honorary teachers has not been fully optimized. Normatively, there are provisions in the National Education System Law, the State Civil Apparatus Law, and various implementing regulations that provide a basis for protection; however, their implementation still faces several challenges, including limited regional budgets, the absence of proper wage standards, and unclear mechanisms for appointment as state civil servants. In addition, weak supervision and uneven regional policies further exacerbate the condition of honorary teachers. The conclusion of this study emphasizes that legal protection for honorary teachers in Cianjur Regency requires the strengthening of more specific regulations, increased commitment from local governments, and policy harmonization between central and regional governments. These efforts are essential to ensure legal certainty, justice, and welfare for honorary teachers as an integral part of the national education system.
