Space security has emerged as a concern for the European Union (EU), given that space systems have become integral to ensuring the safety of all European society. This strategy reflects the interaction of geopolitical dynamics and the rising specter of hybrid threats. However, grappling with hybrid threats targeting the EU space presents distinct challenges, primarily owing to their elusive nature. Hence, our objective is to develop practical methodologies to identify and mitigate such threats effectively. To meet this objective, we propose an innovative 8-step process. This approach streamlines the systematic identification and analysis of discourses of hybrid threats within online platforms dedicated to EU space discussions. Our methodology underwent rigorous scrutiny, including a comprehensive literature review that prioritized peer-reviewed manuscripts from sources such as Web of Science and Elsevier Scopus. Additionally, we selected documents from Google Scholar to ensure comprehensive coverage of diverse scholarly contributions, enriching the depth of our analysis. Our research yielded a conceptual framework for Online Discourse Analysis (ODA) tailored to evaluate hybrid threats targeting EU space defense and security. The results highlight the importance of leveraging advanced ODA techniques to deepen our understanding of emerging threats. In conclusion, we advocate for the adoption of these innovative methods to enhance the robustness of EU space defense strategies in the face of evolving security scenarios. The establishment of the 8-step ODA framework marks a pivotal milestone, offering a structured approach to deciphering hybrid threats. Looking ahead, we aim to empirically validate this framework by creating and deploying custom-tailored software designed to identify potential hybrid threats jeopardizing the security of European space assets. Through continued research and practical implementation, we endeavor to fortify the EU's defenses against emerging threats in the space domain.
空间安全已成为欧盟（EU）关注的焦点，因为空间系统已成为确保所有欧洲社会安全的不可或缺的组成部分。该战略反映了地缘政治动态和混合威胁抬头的相互作用。然而，应对针对欧盟空间的混合威胁带来了独特的挑战，主要是由于它们难以捉摸的性质。因此，我们的目标是开发实用的方法来有效地识别和减轻这些威胁。为了实现这一目标，我们提出了一个创新的 8 步流程。该方法简化了在专门讨论欧盟空间的在线平台上系统地识别和分析混合威胁话语的过程。我们的方法经过了严格的审查，包括对同行评审手稿的全面文献综述，这些手稿来自 Web of Science 和 Elsevier Scopus 等来源。此外，我们还从 Google Scholar 中选择了文档，以确保全面涵盖各种学术贡献，从而丰富了我们的分析深度。我们的研究提出了一个针对在线话语分析（ODA）的概念框架，旨在评估针对欧盟空间防御和安全的混合威胁。研究结果强调了利用先进的 ODA 技术来加深我们对新兴威胁的理解的重要性。总之，我们主张采用这些创新方法，以增强欧盟空间防御战略在不断变化的安全环境下的稳健性。建立 8 步 ODA 框架是一个关键的里程碑，为解析混合威胁提供了一种结构化的方法。展望未来，我们的目标是通过创建和部署专门设计用于识别威胁欧洲空间资产安全的潜在混合威胁的定制软件，来对该框架进行实证验证。通过持续的研究和实际的实施，我们努力加强欧盟在空间领域抵御新兴威胁的能力。
