The Amiga by it's nature is very insecure and open. If a person wanted to secure the Amiga, they'd really have to start with the early boot control which would allow anyone to bypass OS security. I thought of a hardware solution, a relay disconnecting one of the mouse lines until software in the startup triggered it to reconnect or a keylock triggers it.
Would there be a software solution to prevent a user from bypassing the startup-sequence? Maybe a custom filesystem in the RDB that calls a seperate startup file?
