It is very rare that a student uses an authorized console, unless you've given them access to the console program. However if you suspect that someone has the Teacher Console, there is a utility located in the Utilities folder on the CD called security.exe.
This program logs all Insight activity and can help you quickly identify unauthorized consoles. In Insight v7.0 you can watch the security messages in the status window.
