Might sound a bit of a silly question. I see people talking about threat models, and privacy guides which say things like “if this is part of your threat model, do X Y Z”. I’m just not sure if it’s a general “this is what I want to protect myself against” or if there’s more to it.
That’s basically it. It’s the things you either think are likely threats or the threats you want to be protected from.
It’s why people often ask what’s in someone’s threat model, because each is individual. More security/privacy usually comes with tradeoffs, so just “do the most secure thing always” isn’t necessarily the best solution for everyone.
