I have, unexpectedly, been asked to speak at a class for network security that will cover wired, wireless security as well as internet security for dial-up and high-speed users. I don't have a lot of time to prepare this class. So I am looking for suggested topics. I can prepare the topics I am just looking to cover my bases. I will have about 1 hour. Some of it will be lecture and some of it will be Q&A. Target audience will be retired to semi-retired users who's children have bought them a computer or they have bought a computer and they are trying to learn how to use it. What highlights would you cover? I plan on covering wireless security as far as WEP, controled DHCP, limited number computers. I plan on covering AV programs both freeware and non-freeware. I plan on covering spy-ware etc... I am a little lost on dial-up security. I have never had the need to do that. What is avaiable. Does Windows built-in firewall cover dial-up connections? And does ZoneAlarm cover dial-up? Is Zone Alarm free or pay? Anything else I should cover? When you first got a computer what do you wish someone had told you?
