害制造商的名声。为了便于分析，我们首先要研究一下在其他物联网产品上已经确认了
的安全问题，看看我们的原型是否有相似的漏洞问题。然后，我们再讨论另一种安全机制，
实现该安全机制能够让我们的原型更加安全，接着评估一下当前已存在的物联网安全框
架，以确保方法的全面性。
7.2.1 WiFi
虽然方便，但不安全
我们要做的第一件事就是创建一个工作原型配置
cloudBit
，使其能提供有效地认证信息，
访问到我们的家庭
WiFi
网络（如图
7-11
所示）。最终的产品也需要用户输入类似方式
的
WiFi
认证信息。但是，对于我们来讲，它是我们了解设计是否存在潜在危险的很重
要的因素。
现在，我们必须要加入到一个由我们的
cloudbit
配置暴露的临时
WiFi
网络中。一旦
加入到
cloudBit
网络中，浏览器就会连接到
cloudBit
的
web
服务器上（
IP
地址为
10.0.0.1
），并请求资源
http://10.0.0.1/scan-wifi
，返回的输出如图

一旦浏览器从
cloudBit
那里获取了网络列表，就会将结果呈现给用户（如图

当用户选择自己的家庭网络并输入认证新信息之后（如图 ...
