Making Connections Secure
VNC Server (Enterprise) and VNC Server (Personal) are designed to permit authenticated and encrypted
connections between a host and any number of client computers out-of-the-box. This chapter explains how
to configure VNC Server to relax the authentication and encryption rules if you consider it safe to do so.
Conversely, you can tighten the encryption rules for VNC Server (Enterprise) if required.
Note: VNC Server (Free) can only authenticate connections. Upgrade the host computer to VNC Server
(Enterprise) or VNC Server (Personal) if security is important to you.
This chapter also explains how to configure VNC Server to protect the host computer from accidental or
malicious damage by particular connected users, either by restricting their access to RealVNC remote
control features while connections are in progress, or by preventing them from connecting in the first place.
