Internet Safety

I have always known that it is important to be careful about what information I send over the internet, but I have never done anything about it. I guess I am a pretty naive person, I never think that people are actually going to try and get someone's personal information to do bad things with it. I can not comprehend why someone would want to send viruses and other harmful things to people, but apparently people do those types of things for fun. Right after class I went and changed all my security settings on my facebook account to make it more private. While I was reading online about internet safety, the most common thing that I read was to not put your full name, entire birthdate, telephone number, address, and any other personal identification numbers online.
It is important that as a teacher I teach the students about internet safety. Some parents may not teach their children about it, so where else are they going to learn about being safe on the internet? Even if a student's parent does teach them, it is never a bad thing to be constantly reminded about it.
After researching internet safety, I went home and taught my roommates about it. Right after I finished talking, everyone went and changed their security settings on facebook, and made sure their banking site had an "s" after the http.
I have learned a lot from studying internet safety, and I will definitely be more careful about what I share over the internet!
