Thanks so much for this. I am new to cyber patriot and was fumbling blindly last year trying to find decent checklists and this will help a lot

Once again, thank you for your very informative advice on hardening these operating systems :)

Sometimes forensic questions ask what version of Linux you are running and if you do updates before the README and Forensic questions then you may lose the answer so always do the read me and the Forensic Questions first.

Thanks for making this great video! I really appreciate it. I heard you mention shadow files and a passdvd file (or something like that) around 17:10. Can you expound on that a bit?

Another great video! Do you think you could do one of these videos with windows server 2019 possibly?

Whenever I try to install Bum it says it's unable to locate package.

If only forensics questions were that easy… :)

For firewall do you leave it on home for cyber patriot? I always put it on office but I don’t know what it does.
