一、内容摘要（Content summary）

本期推文将从思维导图、精读内容、知识补充三个方面介绍精读期刊论文《混源操作系统供应链安全风险评估方法研究》的引言。

This issue of tweets will introduce the introduction of the journal paper "Research on Supply chain Security Risk assessment Method of Mixed source Operating System" from three aspects: mind mapping, intensive reading content, and knowledge supplement.

二、思维导图（Mind Mapping）

三、精读内容（Detailed Reading Content）

在引言部分，作者首先介绍了本文内容的研究背景。近年来，软件供应链安全风险日益凸显，典型案例包括2021年10月NPM开发者账号被劫持导致恶意包传播，以及同年12月Apache Log4j漏洞波及超17万下游组件的事件。此类攻击具有隐蔽性高、扩散性强、成本低且收益大的特点，正推动全球供应链安全事件激增，急需从开发、分发到依赖管理的全链路加强防护。

In the introduction part, the author first presents the research background of the content of this article. In recent years, security risks in the Software supply chain have become increasingly prominent. Typical cases include the hijacking of NPM developer accounts in October 2021, which led to the spread of malicious packages, and the incident in December of the same year where the Apache Log4j vulnerability affected more than 170,000 downstream components. Such attacks are characterized by high concealment, strong spread, low cost and high returns. They are driving a sharp increase in global supply chain security incidents and urgently need to enhance protection throughout the entire chain from development, distribution to dependency management.

然后，提出了本文的研究问题。当前软件供应链安全风险评估的研究进展，指出代表性方法包括基于指标体系和基于风险驱动因素的评估方法。然而，这些方法在评估混源操作系统时存在局限性：未区分不同来源代码的差异性影响，现有文献的驱动因素主要针对商业软件供应商，难以适配开源社区和自研代码混合的场景，且缺乏定量分析能力。因此，现有方法无法准确评估混源操作系统因代码来源多样、演化路径独立带来的供应链安全风险差异性。

Then, the research questions of this paper were raised. The current research progress on software supply chain security risk assessment indicates that representative methods include assessment methods based on index systems and risk-driven factors. However, these methods have limitations when evaluating mixed-source operating systems: they fail to distinguish the differential effects of different source codes. The driving factors of existing literature mainly target commercial software suppliers, making it difficult to adapt to scenarios where open-source communities and self-developed codes are mixed, and lacking quantitative analysis capabilities. Therefore, the existing methods cannot accurately assess the differences in supply chain security risks brought about by the diverse code sources and independent evolution paths of mixed-source operating systems.

最后，总结了本文的研究内容。该文以通用操作系统为研究对象，聚焦软件包粒度的代码来源分析，通过融合可用性、可替代性与安全因素，提出供应链安全的可溯性、可用性和安全性保障目标，并基于混源操作系统供应链特点构建了多级风险评估指标体系及量化方法，同时验证了其可行性与有效性，还探讨了相关技术手段与工具在指标评估中的应用。

Finally, the research content of this paper was summarized. This paper takes the general operating system as the research object, focuses on the code source analysis at the software package granularity, and by integrating availability, substitutability and security factors, proposes the traceability, availability and security guarantee goals of supply chain security. Based on the characteristics of the supply chain of the mixed-source operating system, a multi-level risk assessment index system and quantitative method are constructed, and its feasibility and effectiveness are verified at the same time. The application of relevant technical means and tools in the evaluation of indicators was also discussed.
