CFI Liabilities

I am a fresh CFI looking to do some flight reviews for people I know who own airplanes and I was thinking, how do I properly protect myself from a possible incident? Of course I can get CFI insurance but is there more I should be doing? I don’t want to go up and have a bad landing with a student or something and then get sued into oblivion because I wasn’t covered on the owners insurance or something even if I was flying with the owner. Let me know if I’m just over thinking it or if I should be doing something different or any other pointers like how much I should be insured for. Thanks!
