A Deeper Analysis of Adversarial Examples in Intrusion Detection

(1, 2) , (2) , (2) , (1)


During the last decade, machine learning algorithms have massively integrated the defense arsenal made available to security professionals, especially for intrusion detection. However, and despite the progress made in this area, machine learning models have been found to be vulnerable to slightly modified data samples called adversarial examples. Thereby, a small and well-computed perturbation may allow adversaries to evade intrusion detection systems. Numerous works have already successfully applied adversarial examples to network intrusion detection datasets. Yet little attention was given so far to the practicality of these examples in the implementation of end-to-end network attacks. In this paper, we study the applicability of network attacks based on adversarial examples in real networks. We minutely analyze adversarial examples generated with state-of-the-art algorithms to evaluate their consistency based on several criteria. Our results show a large proportion of invalid examples that are unlikely to lead to real attacks.
