Categorical Robustness Assessment for Machine Learning based Network Intrusion Detection Systems

arXiv:2606.12075v1 Announce Type: cross Abstract: Network Intrusion Detection Systems (NIDS) heavily utlize Machine Learning (ML) but ML models can be manipulated via adversarial attacks. These attacks add carefully crafted perturbations to network traffic data that leads to misclassifications. While prior work has demonstrated adversarial vulnerabilities in isolated settings, systematic cross-architecture as well as class and category of attack based comparisons under controlled attack conditions remain limited, leaving practitioners without clear guidance on which models to deploy in adversa

Why this matters
Why now

The increasing reliance on Machine Learning in Network Intrusion Detection Systems (NIDS) and the growing sophistication of adversarial methods necessitate a deeper understanding of ML model robustness.

Why it’s important

This research provides crucial insights into the vulnerabilities of AI-driven cybersecurity defenses, which could impact national security, critical infrastructure, and corporate data integrity.

What changes

The systematic comparison of adversarial vulnerabilities across different ML architectures in NIDS offers clearer guidance for practitioners, potentially leading to more resilient cybersecurity deployments.
