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.
Threat plan.
Ask yourself the following:
What do you have that you want to protect?
Who do you want to protect it from?
How likely is it that you will need to protect it?
How bad are the consequences if you fail?
How much trouble am you willing to go through to prevent these consequences?
After you feel you have answered these sufficiently, you can begin to prepare to protect yourself!
