Analysis And Classification Of Adversarial Machine Learning Attacks Against Machine Learning-Based Network Intrusion Detection Systems

Network Intrusion Detection Systems (NIDS) play a critical role in modern cybersecurity infrastructures by monitoring network traffic and identifying suspicious or malicious activities. In recent years, machine learning techniques have significantly improved the performance of intrusion detection systems by enabling automated traffic analysis and anomaly detection. However, the integration of machine learning into security systems also introduces new vulnerabilities that can be exploited by attackers. One such threat is adversarial machine learning, where malicious actors manipulate training or testing data to deceive machine learning models and degrade their performance. This study presents a comprehensive analysis of adversarial machine learning attacks targeting network intrusion detection systems. The work explores how adversarial samples are generated by introducing small perturbations into original datasets, which results in incorrect predictions by the intrusion detection model. Furthermore, the paper classifies adversarial attacks based on several criteria, including attacker knowledge level, misclassification objectives, affected learning phase, and the intended security violation. Understanding these attack strategies is essential for designing more robust and secure intrusion detection systems capable of defending against adversarial manipulation.
