Hmm. Totally depends on the school - different schools, even different school districts.
From other programs I recall - I used to work with them in my first semester this year, actually
- They had a pretty good system set up, I suppose. Of course, they had the occasional.... 'bug,' for lack of a better word, that would give 1 or more random students (which are here classified as numbers in their accounts.) complete staff (note: I said staff
because there is a difference in the teacher and staff privileges on our Novell systems. They had most of the same permissions though.) access to the computer. So, we could shut off the Deep Freeze program that ran on all the computers in the network (except the Dean's, Principal's, and school officer's laptops, I believe), we could even edit the audit script (lucky for me, on my last day working with them, I copied the file to a flash drive to see how it worked.
However, I'm getting off topic. As previously stated, different schools/districts run different programs. As to why that is, I know not. Almost everyone knows that that someone's security will be different from someone else. Although - I always did have a little thought: I thought that perhaps security was different because they have to go out and actually buy the full versions or school-only available programs. And, based on schools, others schools will have more money, as will the the districts, and some won't have as much.
To get off topic again, I'd like to vouch for my school. They learned a thing or two from me, as I did from them. I'm thrilled I had the opportunity to help them, because God knows what would have happened if some punk might have gotten a hold on the systems.
Perhaps when you learn more about their systems, you could ask them for a shot. All I really did was turn the vulnerabilities they had against them (Clark County School District, of course), took some screenshots of my number using the vulns, printed, and reported them - of course, they had wondered why I'd do that for them, and I ended up getting my shot, I suppose. But be careful, though, when you do try something like that - if they catch you, you could end up in some trouble with the law. Perhaps ask, first. Or tell them, and ask to use the vulns against them - reporting them after, of course.
