Madam Speaker, I am not entirely sure how to respond. I do not know the details of how the networks are set up, but a properly run IT system will provide the appropriate firewalls within their systems to prevent data from going where it is not supposed to go. That is the whole purpose of having a high-security system. If security is the issue, then we need to address that issue properly, but Shared Services has an obligation to provide every department with the properly protected systems they need.
