Off-campus remote administration access to critical servers must be available only through encrypted and secure connection methods (e.g., SSH, SSL/VPN).
Consult the help files that are provided with your operating system for guidance.
Any connection to a Queen's server that is initiated from off-campus will travel through networks that are not controlled by Queen's. These networks may have malicious users capturing information that passes through them. If the data that passes through these networks is not encrypted, a malicious user can capture all the passed data (including your username and password) and read it just as easily as reading a Word document.
