For a project I have to do a presentation on computer security. I do not know much about computer security. Antionline is a great resource that i found when I was looking for information but it is very specific in that it talks about specific security practices.

I was wondering is some of the people that frequent here could give me some ideas for what would be useful in a presentation to computer students that are not security experts.

So far I have the basics covered:

What is a virus, worm, spyware

I have a section of AVG anti virus, and ad aware (these were recommended by the professor)

I also have some simple steps for virus prevention.

This gives me about 8 minutes of material and I must say it isnt anything that great. Would you all be able to give me some ideas on other material i could further research that is relevant in todays security world?

Thanks,
Derrick
