摘要：

容器作为一种轻量化隔离方法，具有方便部署、易于移植等特点，近年来发展很快。容器的隔离性阻碍了内部软件成分被外部检测工具所获知，导致软件成分分析、安全评估等无法有效开展，阻碍了软件供应链安全检测。为了解决此问题，文章提出基于依赖关系的容器供应链脆弱性检测方法，区别于利用分析工具在容器运行时进行检测的方法，该方法以镜像为粒度，利用不同镜像中各个层之间的相关性，在解构镜像的基础上提取基于镜像依赖关系形成的软件供应链，能够检测到镜像内容依赖、执行配置依赖和动态构建依赖等多个维度导致的供应链安全问题。实验结果表明，文章所提方法在应对软件供应链的安全威胁时能发挥很好的检测作用，高效地发现了公开容器仓储（如Docker Hub）中存在的大量供应链安全隐患。

Abstract:

As a lightweight isolation method, the container has been widely applied due to its convenient deployment and portability. However, its isolation also naturally prevents its internal software components from being known by external detection tools. It will result in the inability to carry out general software component analysis and evaluation, further hindering threats in the software supply chain. To address this dilemma, this paper proposed a dependency-based vulnerability detection method in container supply chain, which was different from the popular tools that usually analyze by launching the target container. This method took the image as the granularity. The correlation between the layers in different images was used, this paper extracted the software formed based on the container image dependency on the basis of deconstructing the software image. The proposed method could detect supply chain security problems caused by multiple dimensions, such as image-content dependencies, execution-configuration dependencies, and dynamic build dependencies. The experimental results show that the proposed method can make sense in detecting various risks in the software supply chain and efficiently discover a large number of risks in public container repositories (such as Docker Hub).

Key words: software supply chain, container security, security detection, multi-dimensional dependency
