This is my first box ever. It took me a few hours.
Once I became root, I used my root privileges to chattr +i all of the flags and the .bash_history of root and the other two accounts after clearing them. This way no bash history can be recorded, preventing it from giving away clues from other users. Only root will be able to delete critical files now.
Well, on your server and until it is reset, yes.
This could have been done “out of the box” by the author.
True - and certainly worth suggesting. I’ve found quite often Linux boxes desperately need the creator to make critical files immutable - OpenAdmin was a good example of this.
