Security when you’re on untrusted network. I can trust Google to snoop my banking data and update the spending power info on my ad profile, I can’t trust the random dude in trench coat also using the public wifi when I am traveling out of my roaming coverage.
I joke of course, but the security aspect is still valid.
What is it that you're doing that is still not using some form of authenticated encryption? Almost everything is https, ssh, almost all mailservers have tls support, irc does have tls support.. What's left that needs to be encrypted by a VPN?
The addresses themselves that you're connecting to as one example. Also often DNS.
What's the threat model here? I can think of no DNS shennanigans that would not be detectable through the authentication mechainsms in TLS (chain-of-trust). Not having to trust network infrastructure is exactly what TLS is for.
Most DNS requests are clear text, which is why DOH was introduced to secure it such that no one can snoop on you looking up
something-embarrassing.com. Also, the initial request, before you get the SSL certificate from the web server, you must tell the server at169.169.169.169that you’re looking for the certificate forsomething-embarrassing.combefore they can get you the correct certificate. This is why ECH was introduced. Neither of which have became mainstream yet, and so there are still some basic leakage going on.
