These days, the vast majority of administrators go to great lengths to protect the files on their network. Typically, elaborate firewalls are used to keep outsiders away from file servers. The files residing on those servers often lie behind an intricate permissions scheme and are often encrypted. Complex auditing mechanisms might even monitor access to files. The point is that in this day and age, most administrators take security very seriously. What you might not realize though is that all of this security can be easily undone through the simple action of a user accessing a file through legitimate means.
