在IoT中简化访问控制

Making Access Control Easy in IoT

Vafa Andalibi, Jayati Dev, DongInn Kim, Eliot Lear, L. Jean Camp

摘要:

物联网(IoT)设备的安全安装需要为每个设备正确配置访问控制。为了实现正确的配置,互联网工程任务组(IETF)已经开发了制造商使用描述(MUD),以通过使用动态访问控制列表的微分段来自动保护物联网设备。该协议定义了一种概念上简单的方法,通过提供每个设备的每个授权访问的列表,在安装时实现访问控制。该访问控制列表可以包含用于每个设备的几个规则或数百个规则。因此,验证这些规则是一个挑战。为了使MUD标准更适用于开发人员,系统集成商和网络运营商,我们报告一个交互式系统称为MUD可视化,可视化的文件包含这些访问控制规则。我们表明,与手动分析不同,当使用MUD-Visualizer时,知识和经验的水平不会影响分析的准确性,这表明该工具对我们研究中所有知识和经验水平的参与者都有效。

英文摘要:

Secure installation of Internet of Things (IoT) devices requires configuring access control correctly for each device. In order to enable correct configuration the Manufacturer Usage Description (MUD) has been developed by Internet Engineering Task Force (IETF) to automate the protection of IoT devices by micro-segmentation using dynamic access control lists. The protocol defines a conceptually straightforward method to implement access control upon installation by providing a list of every authorized access for each device. This access control list may contain a few rules or hundreds of rules for each device. As a result, validating these rules is a challenge. In order to make the MUD standard more usable for developers, system integrators, and network operators, we report on an interactive system called MUD-Visualizer that visualizes the files containing these access control rules. We show that, unlike manual analysis, the level of the knowledge and experience does not affect the accuracy of the analysis when MUD-Visualizer is used, indicating that the tool is effective for all participants in our study across knowledge and experience levels.
