So, yeah -- this is a really hard problem: mapping technical characteristics such as TLS properties and domain name similarities to actual threats.<p>That's one of the reasons why, in my thesis (which I defend in... 1 week!), I propose replacing replacing security indicators with risk indicators [1]. I think technical properties of a web page, in conjunction with the context of specific interactions, can be used to determine whether the interactions might be risky. By informing users of risks they may be taking, they feel more confident making their own trust decisions.<p>(Meanwhile on the back-end: as a web server developer, I'm trying to find ways to make it easier to do upgrades when vulnerabilities in protocols are fixed, etc. It's also hard.)<p>[1]: <a href="https://twitter.com/mholt6/status/1112748525413031936" rel="nofollow">https://twitter.com/mholt6/status/1112748525413031936</a>
