Hackers Beware!

My last blog for my first class at UC. I honestly thought Dr. Goldberg would have had us to write a blog on what we have learned these last eight weeks. Umm...well, if she did ask that, my answer would be a lot! If ya have been reading my blogs; and especially the one where I told you about my computer history, then you know I would be learning a lot. However, this is not what my blog is about. It is hackers beware.
I sub at school and have for the last nine years. I have been using the school computer for maybe the last five years. It is wonderful to use and I communicate with the teachers I sub. They even email me asking for me to sub. I honestly don't know what kind of protection that our tech gurus have on our systems. It did enter my mind to shoot them an email, but that simply escaped my mind until I am sitting in bed typing this up. In the years that I have been using the school computers, I have not heard of any major issues. Yes, the systems have been down, but that might have lasted half-a-day.
I do know they take the AUP seriously. Many students have had their privileges taken away. My concern with the older students on the computer is that they are able to change the proxy. I learned about this within the last year. This enables them to get on Facebook, MySpace, and any other site that is blocked from school. Another area of concern, and this is a fact, I know of some teachers who sign on for students. NO WAY will I ever do that. The kids have asked me and I am not willing to be called out and have to go in front of the tech judge. I am smarter than that. Not sure what on earth those teachers are thinking about. My guess, they aren't thinking.
I have heard that our tech guys have called a teacher before and told them that computer "five" is looking at ZXY site. The teacher comes over and tells little "Johnny" to get off and if he is caught again he will not have computer privileges.
Pop-ups are blocked and there are many sites that are blocked. (If you don't change the proxy). I have not heard of any teacher's computer being hacked or having any malicious Mal ware. So far so good that I can tell.
Concerns I have are:  A) If the students are able to change the proxy settings and get to blocked sites, then wouldn't that rise the potential for a virus? Yes, and it looks like the school would be able to block changing the proxy. B) If they are able to tell that little "Johnny" is on a blocked site and they call his teacher; why can't they tell when the proxy is changed and call the teacher? I have asked other teachers these exact questions and I get "I don't know". Interesting
