IoT安全的最佳实践:这意味着什么?

Best Practices for IoT Security: What Does That Even Mean?

Christopher Bellman, Paul C. van Oorschot

摘要:

物联网(IoT)安全的最佳实践最近引起了全球工业界和政府的极大关注,而学术研究则强调了许多物联网产品制造商未能遵循公认的实践。我们探讨的不是未能遵循最佳实践,而是令人惊讶的缺乏理解,在文献中,(一般)“最佳实践”的意思是什么,独立于有意义地确定具体的个人做法。混淆是显而易见的,从指导方针,混淆了预期的结果与安全实践,以实现这些结果。最佳实践、良好实践和标准实践有何不同?或指导方针、建议和要求?如果某个做法不可行,它能成为最佳做法吗?我们考虑最佳实践的类别,以及它们如何在物联网设备的生命周期中应用。为了讨论的具体性,我们分析和分类了来自工业、政府和学术来源的1014个物联网安全最佳实践、建议和指南。作为一个示例结果,我们发现这些实践或指南中约有70%与物联网设备生命周期的早期阶段有关,突出了制造商在解决相关安全问题方面的关键地位。我们希望我们的工作为社区提供一个基础,以便更好地了解最佳做法,确定并就具体做法达成共识,然后找到激励相关利益攸关方遵循这些做法的方法。

英文摘要:

Best practices for Internet of Things (IoT) security have recently attracted considerable attention worldwide from industry and governments, while academic research has highlighted the failure of many IoT product manufacturers to follow accepted practices. We explore not the failure to follow best practices, but rather a surprising lack of understanding, and void in the literature, on what (generically) "best practice" means, independent of meaningfully identifying specific individual practices. Confusion is evident from guidelines that conflate desired outcomes with security practices to achieve those outcomes. How do best practices, good practices, and standard practices differ? Or guidelines, recommendations, and requirements? Can something be a best practice if it is not actionable? We consider categories of best practices, and how they apply over the lifecycle of IoT devices. For concreteness in our discussion, we analyze and categorize a set of 1014 IoT security best practices, recommendations, and guidelines from industrial, government, and academic sources. As one example result, we find that about 70\% of these practices or guidelines relate to early IoT device lifecycle stages, highlighting the critical position of manufacturers in addressing the security issues in question. We hope that our work provides a basis for the community to build on in order to better understand best practices, identify and reach consensus on specific practices, and then find ways to motivate relevant stakeholders to follow them.
