"In theory" is one of the scariest phrases in the world of computing. Take this story about vulnerabilities in the computer systems used to run some federal prisons in the USA:
While the computers that are used for the system control and data acquisition (SCADA) systems that control prison doors and other systems in theory should not be connected to the Internet, the researchers found that there was an Internet connection associated with every prison system they surveyed. In some cases, prison staff used the same computers to browse the Internet; in others, the companies that had installed the software had put connections in place to do remote maintenance on the systems.
