摘      要:DL has revolutionized Network Intrusion Detection Systems (NIDS) in recent years. However, these models suffer from Adversarial Examples (AEs), which are maliciously crafted to cause misclassification by a target NIDS. Unlike image recognition, AEs in a network intrusion domain are crafted for evasion and to launch attacks once they have successfully evaded detection. In recent years, several adversarial attack techniques have been developed to generate adversarial examples that retain their maliciousness even after perturbations. This is achieved by only modifying the non-functional features of a malicious data sample. In this paper, we propose a deep autoencoder (DAE) mechanism that can detect adversarial examples that are crafted by only modifying non-functional attributes. The method trains a DAE to establish a latent space relationship between non-functional attributes of feature space data samples. It then uses the inconsistency in the classification result of an AE and latent space relationship between non-functional features for adversarial detection. The paper shows that a DAE trained on only non-functional features produces fewer false positives than a DAE trained on both functional and non-functional features. We evaluate our proposed method on three data sets (CICIDS2017, NSL-KDD, and UNSW-NB15) and against five state-of-the-art AE attacks. Experimentally, our method was able to detect up to 99% AEs with very few false positives.
