WPA2企业级申请者的安全配置实践

(In)Secure Configuration Practices of WPA2 Enterprise Supplicants

Alberto Bartoli, Eric Medvet, Andrea De Lorenzo, Fabiano Tarlao

摘要:

WPA2 Enterprise是企业无线网络中安全通信的基础技术。该技术的关键要求是支持WiFi的设备(即,请求者)在连接到企业无线网络之前进行正确配置。未正确配置的请求者可能会很容易地成为旨在窃取网络凭据的攻击的牺牲品。这种凭证具有巨大的价值,因为它们通常可以解锁对所有企业服务的访问。在这项工作中,我们调查用户和技术人员是否意识到这些重要和广泛的风险。我们进行了两项广泛的分析:对大约1000名用户进行了一项调查,了解他们如何为企业网访问配置WiFi设备;以及对企业网管理员提供的大约310个网络配置指南进行了审查。结果提供了强有力的迹象表明,WPA2企业的关键要求被系统地违反,因此不能再被认为是现实的。

英文摘要:

WPA2 Enterprise is a fundamental technology for secure communication in enterprise wireless networks. A key requirement of this technology is that WiFi-enabled devices (i.e., supplicants) be correctly configured before connecting to the enterprise wireless network. Supplicants that are not configured correctly may fall prey of attacks aimed at stealing the network credentials very easily. Such credentials have an enormous value because they usually unlock access to all enterprise services. In this work we investigate whether users and technicians are aware of these important and widespread risks. We conducted two extensive analyses: a survey among approximately 1000 users about how they configured their WiFi devices for enterprise network access; and, a review of approximately 310 network configuration guides made available by enterprise network administrators. The results provide strong indications that the key requirement of WPA2 Enterprise is violated systematically and thus can no longer be considered realistic.
