NAttack! Adversarial Attacks to bypass a GAN based classifier trained to detect Network intrusion

no code implementations20 Feb 2020 Aritran Piplai, Sai Sree Laya Chukkapalli, Anupam Joshi

In this paper, we show that even if we build a classifier and train it with adversarial examples for network data, we can use adversarial attacks and successfully break the system.
