At my school, we each have our personal hard drives, as well as 5 other network drives and 2 hard-drives per computer. One of the shared network drives (known as drive K:/) has Counter-Strike: Source Portable edition on it. However, my school seems competent on computers, and actually monitors most of them. One of the few security flaws they have is all the school's security cameras are on the same network as the school's computers, so hackers can see everything going on in class (which has happened).
