AI 中文总结

该研究提出DUPIN方法,先对海量审计事件做无监督预训练,再用少量带标签攻击示例微调检测能力,经25个APT攻击活动评估,其作为灵活取证学习者表现良好。

AI 中文摘要

我们提出一种名为DUPIN的新型基于学习的攻击取证方法。DUPIN以溯源图形式对海量审计事件执行无监督预训练,随后进入少样本学习阶段,利用少量带标签的攻击示例微调其检测能力。我们在长达38-52天的审计日志(总计7.3TB)上预训练DUPIN,并针对四个不同数据源的25个APT攻击活动,在多种基准方法上对其进行评估,以实现可扩展评估。

英文摘要

We propose a novel approach to learning-based attack forensics called DUPIN. DUPIN performs unsupervised pre-training on an enormous amount of audit events in the form of provenance graphs. It then proceeds to a few-shot learning stage, leveraging a small number of labeled attack examples to fine-tune its detection capabilities. We pretrain DUPIN on up to 38 - 52 days of audit logs (7.3TB total) and evaluate it against various baselines on 25 APT campaigns across four different data sources, facilitating the scalable evaluation.
