基于系统级起源图的威胁检测与调查研究综述

Threat Detection and Investigation with System-level Provenance Graphs: A Survey

Zhenyuan Li, Qi Alfred Chen, Runqing Yang, Yan Chen

摘要:

随着信息技术的发展,网络空间的边界越来越宽,暴露在攻击者面前的漏洞也越来越多。传统的以缓和为基础的防御战略难以应对当前的复杂局势。安全从业人员迫切需要更好的工具来描述和建模攻击防御。起源图具有强大的语义表达能力和攻击历史关联能力,是一种理想的威胁建模方法。本文首先介绍了系统级起源图的基本概念,提出了基于起源图的威胁检测与调查的典型系统架构。一个基于起源图的综合威胁检测系统可以分为三个模块,即“数据汇集模块”、“数据管理模块”和“威胁检测模块”。每个模块包含多个组成部分,涉及多个研究问题。我们系统地分析了所涉及的算法和设计细节。通过比较,给出了技术选择的策略.同时指出了现有工作的不足之处,为今后的工作提供了参考。

英文摘要:

With the development of information technology, the border of the cyberspace gets much broader, exposing more and more vulnerabilities to attackers. Traditional mitigation-based defence strategies are challenging to cope with the current complicated situation. Security practitioners urgently need better tools to describe and modelling attacks for defence. The provenance graph seems like an ideal method for threat modelling with powerful semantic expression ability and attacks historic correlation ability. In this paper, we firstly introduce the basic concepts about system-level provenance graph and proposed typical system architecture for provenance graph-based threat detection and investigation. A comprehensive provenance graph-based threat detection system can be divided into three modules, namely, "data collection module", "data management module", and "threat detection modules". Each module contains several components and involves many research problem. We systematically analyzed the algorithms and design details involved. By comparison, we give the strategy of technology selection. Moreover, we pointed out the shortcomings of the existing work for future improvement.
