摘要:

检测或修复恶意网络活动的技术的研究和开发需要访问包含标记的恶意连接的多样化的、现实的、当代的数据集。在没有这些数据的情况下,所述技术不能被有意义地训练、测试和评估。包含伪造或合并的网络流量的合成产生的数据具有有限的价值,因为即使通过简单的机器学习(ML)算法也可以很容易地将其与真实流量区分开。真实的网络数据是更可取的,但普遍存在的是敏感的,缺乏真实的标签,限制了其在机器学习研究中的效用。本文提出了一种多方面的方法来生成嵌入在从大型生产网络收集的匿名网络流量中的标记恶意连接的数据集。真实世界的恶意软件被拆除并引入这些网络中的模拟安全节点,以生成真实的流量,同时保持足够的隔离以保护真实数据和基础设施。网络传感器数据,包括这种嵌入式恶意软件流量,在网络边缘收集并匿名化以供研究使用。在两个主要教育机构按照上述方法收集和制作了网络流量。其结果是一个高度现实的,长期的,多机构的数据集,嵌入式数据标签跨越1.5万亿连接和超过PB的传感器日志数据。该数据集的可用性通过其对我们的人工智能和机器学习(AI/ML)研究计划的实用性来证明。

英文摘要:

Research and development of techniques which detect or remediate malicious network activity require access to diverse, realistic, contemporary data sets containing labeled malicious connections. In the absence of such data, said techniques cannot be meaningfully trained, tested, and evaluated. Synthetically produced data containing fabricated or merged network traffic is of limited value as it is easily distinguishable from real traffic by even simple machine learning (ML) algorithms. Real network data is preferable, but while ubiquitous is broadly both sensitive and lacking in ground truth labels, limiting its utility for ML research. This paper presents a multi-faceted approach to generating a data set of labeled malicious connections embedded within anonymized network traffic collected from large production networks. Real-world malware is defanged and introduced to simulated, secured nodes within those networks to generate realistic traffic while maintaining sufficient isolation to protect real data and infrastructure. Network sensor data, including this embedded malware traffic, is collected at a network edge and anonymized for research use. Network traffic was collected and produced in accordance with the aforementioned methods at two major educational institutions. The result is a highly realistic, long term, multi-institution data set with embedded data labels spanning over 1.5 trillion connections and over a petabyte of sensor log data. The usability of this data set is demonstrated by its utility to our artificial intelligence and machine learning (AI/ML) research program.
