Web浏览器警告应该有助于保护人们免受恶意软件、网络钓鱼和网络攻击。遵守警告让人们在网上更安全。最近对警告设计的改进提高了遵守率，但仍有可能更高。先前的研究表明，许多人仍然不理解它们。因此，仍然存在两个挑战：提高理解和遵从率。为了更深入地挖掘用户对警告的决策和理解，我们进行了一项关于网络浏览器安全警告的体验抽样研究，包括对6000多名Chrome和Firefox用户进行现场调查，以收集坚持或不遵守真正警告的原因。我们发现这些原因很多，而且随着背景的不同而不同。与以前的工作相反，我们在现代警示设计中没有发现单一的主导失败-比如习惯性-阻碍有效决策的失败。我们的结论是，进一步改进警告将需要解决一系列较小的上下文误解。
Web browser warnings should help protect people from malware, phishing, and network attacks. Adhering to warnings keeps people safer online. Recent improvements in warning design have raised adherence rates, but they could still be higher. And prior work suggests many people still do not understand them. Thus, two challenges remain: increasing both comprehension and adherence rates. To dig deeper into user decision making and comprehension of warnings, we performed an experience sampling study of web browser security warnings, which involved surveying over 6,000 Chrome and Firefox users in situ to gather reasons for adhering or not to real warnings. We find these reasons are many and vary with context. Contrary to older prior work, we do not find a single dominant failure in modern warning design---like habituation---that prevents effective decisions. We conclude that further improvements to warnings will require solving a range of smaller contextual misunderstandings.
