Of course, If it's for the total noob, they are not going to kave a clue what you're talking about when you say DDoS. Maybe a good idea to either require an intro to computer concepts or teach it as a part of the curriculum. I wouldn't go too far back (Stonehenge, abacus, Babbage, ARPANET....), just through the evolution of the MS-DOS/Windows/Windows NT OS.

I'd cover topics like basic OS hardening, backups, pop ups, browser hijacks, passwords (not using the same one for everything), the importance of virus scanning, malware, personal software and hardware firewalls, phishing, identity theft, and social engineering overview, what to do when hacked, etc.

Might want to use some PowerPoint or Flash presentations. If you need any material for the class, PM me. I'e got tons of free time and I'd be glad to help.
