一种基于GAN的网络入侵检测方法

Efficient GAN-based method for cyber-intrusion detection

摘要:

无处不在的异常不断危及我们系统的安全。它们可能会对系统造成不可逆转的损害,并导致隐私泄露。因此,及时发现这些异常至关重要。传统的监督方法,如决策树和支持向量机(SVM)被用来分类正常和异常。然而,在某些情况下,异常状态比正常状态少得多,这导致这些方法的决策偏差。生成对抗网络(GAN)已被提出来处理这种情况。它具有很强的生成能力,只需要学习正常状态的分布,并通过它与学习的分布之间的差距来识别异常状态。然而,现有的基于GAN的模型不适合处理具有离散值的数据,导致检测性能大幅下降。为了处理离散特征,在本文中,我们提出了一种高效的基于GAN的模型,具有专门设计的损失函数。实验结果表明,我们的模型优于国家的最先进的模型在离散数据集上,显着降低了开销。

英文摘要:

Ubiquitous anomalies endanger the security of our system constantly. They may bring irreversible damages to the system and cause leakage of privacy. Thus, it is of vital importance to promptly detect these anomalies. Traditional supervised methods such as Decision Trees and Support Vector Machine (SVM) are used to classify normality and abnormality. However, in some case the abnormal status are largely rarer than normal status, which leads to decision bias of these methods. Generative adversarial network (GAN) has been proposed to handle the case. With its strong generative ability, it only needs to learn the distribution of normal status, and identify the abnormal status through the gap between it and the learned distribution. Nevertheless, existing GAN-based models are not suitable to process data with discrete values, leading to immense degradation of detection performance. To cope with the discrete features, in this paper, we propose an efficient GAN-based model with specifically-designed loss function. Experiment results show that our model outperforms state-of-the-art models on discrete dataset and remarkably reduce the overhead.
