摘要:

机器学习(ML)和深度学习(DL)已被用于构建入侵检测系统(IDS)。新的网络攻击的数量和种类的增加对依赖历史攻击特征数据库的IDS解决方案提出了巨大的挑战。因此,工业界对能够标记零日攻击的强大IDS的需求正在增长。目前基于离群值的零日检测研究存在较高的假阴性率,从而限制了其实际应用和性能。本文提出了一种检测零日攻击的自动编码器实现。我们的目标是建立一个具有高召回率的IDS模型,同时将未命中率(假阴性)保持在可接受的最小值。两个著名的IDS数据集用于评估-CICIDS 2017和NSL-KDD。为了证明我们的模型的有效性,我们将其结果与一类支持向量机(SVM)进行比较。该手稿强调了当零日攻击与正常行为不同时单类SVM的性能。所提出的模型大大受益于自动编码器的编码-解码能力。结果表明,自动编码器非常适合检测复杂的零日攻击。结果表明,NSL-KDD数据集的零日检测准确率为[89-99%],CICIDS 2017数据集为[75-98%]。最后,本文概述了召回和辐射之间观察到的权衡。

英文摘要:

Machine Learning (ML) and Deep Learning (DL) have been used for building Intrusion Detection Systems (IDS). The increase in both the number and sheer variety of new cyber-attacks poses a tremendous challenge for IDS solutions that rely on a database of historical attack signatures. Therefore, the industrial pull for robust IDSs that are capable of flagging zero-day attacks is growing. Current outlier-based zero-day detection research suffers from high false-negative rates, thus limiting their practical use and performance. This paper proposes an autoencoder implementation for detecting zero-day attacks. The aim is to build an IDS model with high recall while keeping the miss rate (false-negatives) to an acceptable minimum. Two well-known IDS datasets are used for evaluation-CICIDS2017 and NSL-KDD. In order to demonstrate the efficacy of our model, we compare its results against a One-Class Support Vector Machine (SVM). The manuscript highlights the performance of a One-Class SVM when zero-day attacks are distinctive from normal behaviour. The proposed model benefits greatly from autoencoders encoding-decoding capabilities. The results show that autoencoders are well-suited at detecting complex zero-day attacks. The results demonstrate a zero-day detection accuracy of [89-99%] for the NSL-KDD dataset and [75-98%] for the CICIDS2017 dataset. Finally, the paper outlines the observed trade-off between recall and fallout.
