Advanced machine learning system for classifying network traffic and detecting cyber-intrusion attempts with production-ready MLOps implementation.
In today's rapidly evolving threat landscape, network infiltration attempts are increasingly sophisticated [web:1][web:2]. This system applies machine learning to system log data with the goal of classifying network activity as benign or malicious. We compare Logistic Regression (baseline) with a more complex Decision Tree Classifier, finding that the latter achieves 92.3% accuracy and a 0.92 F1-score, capturing critical non-linear traffic patterns [web:6][web:10].
The research identifies decision trees as more effective for minimizing false negatives, a crucial priority in security contexts [web:6]. We also propose a roadmap for deploying the system into production with a full MLOps lifecycle [web:7][web:10].
- Perform binary classification on network log entries with high accuracy
- Emphasize minimization of false negatives (undetected threats) for enhanced security
- Establish a scalable framework conducive to real-world deployment in security operations centers
- Implement MLOps best practices for continuous integration and deployment [web:7][web:16]
| Metric | Logistic Regression | Decision Tree Classifier |
|---|---|---|
| Accuracy | 85.6% | 92.3% |
| Precision | 0.88 | 0.94 |
| Recall | 0.82 | 0.90 |
| F1-Score | 0.85 | 0.92 |
Key Finding: Decision Tree Classifier outperforms Logistic Regression on all metrics, with recall (0.90) being especially important for preventing missed infiltration attempts [web:6].
