I have collected over many, many years data from many sources, some of which could be questionable - for example an upload page on a web server at home - to the point where I don't completely trust the integrity of the data.
My current plan is to set up a sacrificial laptop that can be reinstalled easily, running a decent security package and scan all disks before importing the data to my main system.
Is this a decent approach? Is it overkill? Are there better/cheaper/easier/more reliable techniques I could consider?
