My superintendent recently I approached me and asked what protections or policies were in place to ensure privacy and confidentiality of e-mails, documents, etc. in regards to the my role as the network administrator. Do your Network Admins need to sign a code of ethics? Or is the general operating procedure to trust them to do their job and stay out of business that is not related to them? I think the Superintendent was trying to ensure protection for the Network Admin if any accusations were to come up.
