One new thing I have learned in this module.... I was interested to see there were so many distinctions for mal-ware and mal-users. I previously would have classified anyone doing wayward things to/with a computer as either a hacker or an unauthorized user, and I thought that any program that went on a computer and did bad things was a virus. I don't know that it will make a difference, but I'm glad to know the difference.
Another thing that impressed me was the information that any computer is vulnerable to attack. I have a MacBook, and have always had a sense of security, because there just aren't Mac viruses. After this module, I thought about it, and realized there are many more Macs out there than there used to be, and people are probably starting to target them. So I downloaded the McAfee virus detection program for MacIntosh computers - FYI, this is available for free to University of Utah students through campus software licensing.
