Starting Today, Google Chrome Will Show Warnings for Non-Logged SSL Certificates (bleepingcomputer.com)
Starting today, Google Chrome will show a full-page warning whenever users are accessing an HTTPS website that's using an SSL certificate that has not been logged in a public Certificate Transparency (CT) log. From a report: By doing so, Chrome becomes the first browser to implement support for the Certificate Transparency Log Policy. Other browser makers have also agreed to support this mechanism in the future, albeit they have not provided more details. This new policy was first proposed by Google engineers in 2016, and was scheduled to enter into effect in October 2017, but was later delayed for 2018.
Why do home devices need to have trusted SSL certs?
Because Service Workers and several other web platform APIs are restricted to secure contexts per W3C's spec. For example, a browser may restrict the Fullscreen API or Presentation API to secure contexts as a mitigation against phishing by replicating the chrome of the operating system and web browser. In such a browser, the web interface of a NAS on which video is stored will not be able to present the video in the full screen.
