Abstract

This paper presents the development and evaluation of methods for detecting cyberattacks on industrial systems using neural network approaches. The focus is on the task of detecting anomalies in multivariate time series, where the diversity and complexity of potential attack scenarios require the use of advanced models. To address these challenges, a transformer-based autoencoder architecture was used, which was further enhanced by transitioning to a variational autoencoder (VAE) and integrating normalizing flows. These modifications allowed the model to better capture the data distribution, enabling effective anomaly detection, including those not present in the training set. As a result, high performance was achieved, with an F1 score of 0.93 and a ROC-AUC of 0.87. The results underscore the effectiveness of the proposed methodology and provide valuable contributions to the field of anomaly detection and cybersecurity in industrial systems.

本文介绍了利用神经网络方法检测工业系统网络攻击的方法的开发和评估。重点是检测多变量时间序列中的异常情况,潜在攻击场景的多样性和复杂性要求使用先进的模型。为了应对这些挑战,我们使用了基于变压器的自动编码器架构,并通过过渡到变异自动编码器(VAE)和整合归一化流量进一步增强了该架构。这些修改使模型能够更好地捕捉数据分布,从而实现有效的异常检测,包括训练集中不存在的异常。因此,该模型取得了很高的性能,F1 得分为 0.93,ROC-AUC 为 0.87。结果凸显了所提方法的有效性,为工业系统的异常检测和网络安全领域做出了宝贵贡献。
