摘要:

异常检测对于确保网络物理系统(CPS)的安全至关重要。然而,由于CPS的日益复杂和更复杂的攻击,传统的异常检测方法,面对不断增长的数据量,需要特定领域的知识,不能直接应用于解决这些挑战。为此,已经提出了基于深度学习的异常检测(DLAD)方法。在本文中,我们回顾了CPS中最先进的DLAD方法。我们提出了一个分类的异常,战略,实施和评估指标的类型,以了解当前方法的基本属性。此外,我们利用这种分类法,以确定和突出新的特点和设计在每个CPS域。此外,我们还讨论了这些方法的局限性和开放的问题。此外,为了让用户在实践中选择合适的DLAD方法,我们通过实验探索了典型神经模型的特点,DLAD方法的工作流程,以及DL模型的运行性能。最后,我们讨论了DL方法的不足之处,我们的研究结果,以及可能的方向,以改善DLAD方法和激励未来的研究。

英文摘要:

Anomaly detection is crucial to ensure the security of cyber-physical systems (CPS). However, due to the increasing complexity of CPSs and more sophisticated attacks, conventional anomaly detection methods, which face the growing volume of data and need domain-specific knowledge, cannot be directly applied to address these challenges. To this end, deep learning-based anomaly detection (DLAD) methods have been proposed. In this paper, we review state-of-the-art DLAD methods in CPSs. We propose a taxonomy in terms of the type of anomalies, strategies, implementation, and evaluation metrics to understand the essential properties of current methods. Further, we utilize this taxonomy to identify and highlight new characteristics and designs in each CPS domain. Also, we discuss the limitations and open problems of these methods. Moreover, to give users insights into choosing proper DLAD methods in practice, we experimentally explore the characteristics of typical neural models, the workflow of DLAD methods, and the running performance of DL models. Finally, we discuss the deficiencies of DL approaches, our findings, and possible directions to improve DLAD methods and motivate future research.
