0) This write-up is intended to be a general explanation of what constitutes a strong password. Bare with me, for now! As it turns out, this quickly because a very complicated topic. This page will get completed once I put together a clean, and meaningful, explanation for all the recommendations included. 1) Configure Root A) Set a strong password using the command:
 passwd

There are tools that utilize dictionary words (and permutations thereof) to bruteforce, the same way that other tools use characters.
