TWC: Medium: Handling a Trillion Unfixable Flaws on Billions of Internet-of-Things

物联网（IoT）已经迅速从概念变为现实，据估计，到2020年，已部署的物联网设备数量将增加到250亿。然而，研究表明，许多物联网设备存在严重的安全漏洞。此外，物联网设备的局限性和物联网设备网络的规模往往使传统的IT安全方法不切实际。该项目采用第一原则方法来重新思考网络安全，并解决物联网网络的这些问题：(1)简单外围防御的可扩展替代方案；(2)物联网设备部署网络安全管理新方法；(3)具有足够通用性的新安全策略，以管理许多不同用例中的物联网设备和网络。通过提供一个有原则的架构来保护物联网部署，该项目将有助于实现物联网的全部潜在社会效益。该项目将开发出新颖的开源工具、建模抽象、算法和原型实现，这将减少部署新型物联网安全解决方案的时间，并使项目结果可供社区使用。该项目的pi将参与教育和推广活动，为新兴的物联网领域培养下一代人才。特别是，pi计划将跨学科的研究理念整合到跨越安全，网络，系统和网络物理系统的课程中。该项目还将积极鼓励代表性不足的群体参与。最后，该项目产生的工具和测量将通知并加速行业向安全可靠的普及物联网部署的过渡。

The Internet-of-Things (IoT) has quickly moved from concept to reality, with estimates that the number of deployed IoT devices will rise to 25 billion in 2020. However, studies show that many IoT devices have serious security vulnerabilities. Moreover, the limitations of IoT devices and scale of networks of IoT devices often make traditional IT security approaches impractical. This project takes a first-principles approach to rethinking network security and address these concerns for IoT networks: (1) scalable alternatives to simple perimeter defenses; (2) new methods to manage security in deployed networks of IoT devices; and (3) new security policies with sufficient generality to administer IoT devices and networks in many diverse use-cases. By providing a principled architecture to secure IoT deployments, the project will help realize the full potential societal benefits of IoT. The project will result in the development of novel open-source tools, modeling abstractions, algorithms, and prototype implementations that will reduce the time to deploy novel IoT security solutions, and make the results of the project available to the community. The project's PIs will engage in educational and outreach activities to train the next generation talent for the emerging area of IoT. In particular, the PIs plan to integrate the interdisciplinary research ideas into courses spanning security, networking, systems and cyber-physical systems. The project will also actively encourage participation from underrepresented groups. Finally, the tools and measurements generated by this project will inform and accelerate the industry transition to pervasive IoT deployments that are safe and secure.
