My recent experience as a Machine Learning (ML) Engineer with 2+ years. Familiar with ML methodologies, namely data preprocessing, training phase, and testing phase. In data preprocessing, it can be ascertained that data cleaning, data transform and feature selection have been carried out so that they can be implemented in model building at the training phase. After obtaining the most suitable model, a final model is made, then the final model is applied in the model evaluation at the testing phase, the results of which can be measured by metrics. My thesis is about the Development of Machine Learning-Based Intrusion Detection System.

My experience as a Software Engineer/Developer for 3 years has made me familiar with software development both front end with HTML, CSS and Javascript and back end with PHP framework and MySQL, Oracle and PostgreSQL databases. When I was a System Analyst for 10 years, I also made the scope of API and database development and directed vendors in designing according to application needs, including using the API Management System and changing the repository from SVN to Git and implementing CI/CD using Jenkins. In both roles I also bridge the needs of internal users and ensure the successful implementation of the application by the vendor. When creating ToR for IT projects, also conduct research on the development of IT technology that will enhance system capabilities according to EA with an understanding of the architecture of Business Processes, Data, Applications and Infrastructure.

Development of Machine Learning-Based Intrusion Detection System Methods at the Feature Selection, Class Balancing, and Ensemble Learning Stages [Master Thesis]

Researcher

Abstract: The risk of cyberattacks is directly proportional to the growth of applications and computer networks. An Intrusion Detection System (IDS) is implemented to detect cyber attacks in network traffic. However, there are problems detecting unknown attacks or new types of attacks. In addition, there are performance issues regarding detection time, detection accuracy, and false alarms. A machine learning approach takes anomaly detection in network traffic to reduce these problems. The development and utilization of IDS with machine learning have been applied in several studies to improve performance and evaluate attack detection predictions. Choosing the right machine learning approach is necessary to improve the accuracy of cyberattack detection. This research uses a homogeneous ensemble learning method that optimizes tree algorithms, especially gradient boosting tree - LightGBM. The Communications Security Establishment and Canadian Institute of Cybersecurity 2018 (CSE-CIC-IDS 2018) dataset evaluated the proposed approach. The Polynom-fit SMOTE (Synthetic Minority Oversampling Technique) method solved the dataset imbalance problem. The application of spearman's rank correlation coefficient method to the dataset resulted in 24 subset features of the 80 dataset features used to evaluate the model. The proposed model achieves 99% accuracy; precision 99.2%, recall 97.1%; F1-score 98.1%; ROC-AUC 99.1%; and an average-PR of 98.1% and increased the training time of the model from 3 minutes 25.10 seconds to 2 minutes 39.68 seconds.

Anomaly Intrusion Detection System Based On Homogeneous Ensemble Learning with Oversampling and Feature Selection [Conference Paper]

Researcher

Abstract: The risk of cyberattacks is directly proportional to the growth of applications and computer networks. The Intrusion Detection System (IDS) detects anomalies in network traffic to reduce this risk. A machine learning approach is needed related to this. The development and utilization of IDS with machine learning have been applied in several studies. Choosing the right machine learning approach is needed to improve cyberattack detection. In this study, we used a homogeneous ensemble learning method that optimizes the tree algorithm. The Communications Security Establishment and Canadian Institute of Cybersecurity 2018 (CSE-CIC-IDS 2018) dataset were used to evaluate the proposed approach. The Polynom-fit SMOTE (Synthetic Minority Oversampling Technique) method was used to resolve the imbalanced dataset problem. 23 feature subset results from the application of feature selection on the dataset were used to evaluate the model. The proposed model achieved 99% accuracy; 99,2% precision, 97,1% recall; and 98,1% F1-score.
