安全安装物联网(IoT)设备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)开发了制造商使用说明(MUD),通过使用动态访问控制列表的微分段来自动化物联网设备的保护。该协议定义了一种概念上简单的方法,通过为每个设备提供每个授权访问的列表,在安装时实施访问控制。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,验证这些规则是一项挑战。为了使MUD标准更便于开发人员、系统集成商和网络运营商使用,我们报告了一个名为MUD-Visualizer的交互系统,该系统将包含这些访问控制规则的文件可视化。我们表明,与人工分析不同,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的所有参与者都是有效的,跨越知识和经验水平。
Secure installation of Internet of Things (IoT) devices requires configuring access control correctly for each device. In order to enable correct configuration 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.
