The outbreak of the COVID-19 pandemic crisis around the world and the resulting unprecedented measures taken by governments required organizations to quickly adopt new ways of (remotely) working. At face value, this would suggest a higher vulnerability for cyber threats. This research note analyses how a global financial institution dealt with this challenge by using Hollnagel's four abilities for resilient performance as a theoretical lens. Semi-structured in-depth interviews with eleven key actors were conducted. Three findings stand out. First, the interviews suggest that the organization performed cyber resiliently in the sense that the number of incidents and impact were not significantly higher. Second, the interviews show that all four abilities of resilience were formally developed prior to the COVID-19 outbreak, but rarely resulted in anticipatory adjustment. Third, the interviews indicate that the ability to respond contributed most to the organization's cyber resilience during the pandemic crisis. To conclude, our research note raises the question to what extent the four potentials should be developed beforehand in order to perform resiliently during crises.

COVID-19 大流行危机期间的网络弹性：案例研究

全球 COVID-19 大流行危机的爆发以及政府由此采取的前所未有的措施要求组织迅速采用新的（远程）工作方式。从表面上看，这表明网络威胁的脆弱性更高。本研究报告分析了一家全球金融机构如何通过使用 Hollnagel 的四种弹性表现能力作为理论视角来应对这一挑战。对 11 位关键人物进行了半结构化深度访谈。三个发现脱颖而出。首先，采访表明，从事件数量和影响没有显着增加的意义上说，该组织在网络方面表现出色。其次，采访表明，所有四种复原能力都是在 COVID-19 爆发之前正式发展的，但很少导致预期调整。第三，采访表明，在大流行危机期间，响应能力对组织的网络弹性贡献最大。总而言之，我们的研究报告提出了一个问题，即应在多大程度上预先开发这四种潜力，以便在危机期间发挥弹性。
