Abstract

ABSTRACTOver the past few years, many intellectuals have focused on unsupervised learning for anomaly detection in IoT networks. Deploying an unsupervised Autoencoder algorithm for Intrusion Detection System (IDS) is computationally intensive for IoT devices with limited resources. In this work, we propose two distinct AI models using Post-Training Quantization; Quantized Autoencoder float16 (QAE-float16) and Quantized Autoencoder uint8 (QAE-uint8). QAE models are derived using Autoencoder models, which work on the assumption of generating high Reconstruction Error (RE) for anomaly data. Post Training Quantization includes pruning, clustering, and Quantization techniques. The proposed models were tested against the RT-IoT23 dataset, which includes normal and attack traces. This study is focused on the three major types of attacks, namely SSH brute-force, UFONet and DDoS (Distributed Denial of Service) exploitation. Since these attacks are the gateway for future exploitation. The model performance evaluated on IoT devices reveals that QAE-uint8 is the most efficient model by a wide margin, with average memory utilization decreased by 70.01%, memory size compressed by 92.23%, and peak CPU utilization decreased by 27.94%. Therefore, the proposed QAE-uint8 model has the potential to be used in low-power IoT Edge devices to detect anomalies.KEYWORDS: Anomaly detectionartificial intelligenceautoencodersIoTIDSpost-quantization training Disclosure statementNo potential conflit of interest was reported by the authors.
QAE-IDS:使用后量化训练的物联网设备中的DDoS异常检测
在过去的几年里,许多知识分子都在关注物联网网络中用于异常检测的无监督学习。为入侵检测系统(IDS)部署无监督自编码器算法对于资源有限的物联网设备来说是计算密集型的。在这项工作中,我们使用训练后量化提出了两种不同的人工智能模型;量化的自动编码器float16 (QAE-float16)和量化的自动编码器uint8 (QAE-uint8)。基于对异常数据产生高重构误差(RE)的假设,利用自编码器模型推导出了QAE模型。培训后量化包括修剪、聚类和量化技术。提出的模型针对RT-IoT23数据集进行了测试,其中包括正常和攻击痕迹。本研究的重点是三种主要的攻击类型,即SSH暴力破解、UFONet和DDoS(分布式拒绝服务)利用。因为这些攻击是未来利用的门户。在物联网设备上评估的模型性能表明,QAE-uint8是最有效的模型,平均内存利用率降低了70.01%,内存大小压缩了92.23%,峰值CPU利用率降低了27.94%。因此,提出的QAE-uint8模型有潜力用于低功耗物联网边缘设备来检测异常。关键词:异常检测人工智能自动编码器siotidpost -量化训练披露声明作者未报告潜在利益冲突
