摘要:

用有监督的机器学习(ML)增强网络入侵检测系统(NIDS)是一项艰巨的任务。ML-NIDS必须经过培训和评估,操作需要明确标记良性和恶意样本的数据。这样的标签需要昂贵的专业知识,导致缺乏真正的部署,以及论文总是依赖于相同的过时数据。最近情况有所改善,因为一些努力披露了他们的标记数据集。然而,大多数过去的作品使用这样的数据集只是作为一个“又一个”测试平台,忽略了这种可用性提供的额外潜力。相比之下,我们提倡使用这种现有的标记数据来交叉评估ML-NIDS。这种方法只得到有限的注意,由于其复杂性,需要专门处理。因此,我们提出了第一个交叉评估模型。我们的模型突出了更广泛的现实用例,可以通过交叉评估进行评估,允许发现最先进的ML-NIDS的未知品质。例如,它们的检测表面可以扩展-而不需要额外的标签费用。然而,进行这种交叉评价具有挑战性。因此,我们提出了第一个框架,XeNIDS,可靠的交叉评估的基础上网络流。通过在六个知名数据集上使用XeNIDS,我们展示了ML-NIDS交叉评估的隐藏潜力和风险。

英文摘要:

Enhancing Network Intrusion Detection Systems (NIDS) with supervised Machine Learning (ML) is tough. ML-NIDS must be trained and evaluated, operations requiring data where benign and malicious samples are clearly labelled. Such labels demand costly expert knowledge, resulting in a lack of real deployments, as well as on papers always relying on the same outdated data. The situation improved recently, as some efforts disclosed their labelled datasets. However, most past works used such datasets just as a 'yet another' testbed, overlooking the added potential provided by such availability. In contrast, we promote using such existing labelled data to cross-evaluate ML-NIDS. Such approach received only limited attention and, due to its complexity, requires a dedicated treatment. We hence propose the first cross-evaluation model. Our model highlights the broader range of realistic use-cases that can be assessed via cross-evaluations, allowing the discovery of still unknown qualities of state-of-the-art ML-NIDS. For instance, their detection surface can be extended--at no additional labelling cost. However, conducting such cross-evaluations is challenging. Hence, we propose the first framework, XeNIDS, for reliable cross-evaluations based on Network Flows. By using XeNIDS on six well-known datasets, we demonstrate the concealed potential, but also the risks, of cross-evaluations of ML-NIDS.
