VNC stands for Virtual Network Computing. It is remote control software which allows you to view and fully interact with one computer desktop (the "VNC server") using a simple program (the "VNC viewer") on another computer desktop anywhere on the Internet. The two computers don't even have to be the same type, so for example you can use VNC to view a Windows Vista desktop at the office on a Linux or Mac computer at home. For ultimate simplicity, there is even a Java viewer, so that any desktop can be controlled remotely from within a browser without having to install software.
VNC is in widespread active use by millions throughout industry, academia and privately.
VNC has a wide range of applications including system administration, IT support and helpdesks. It can also be used to support the mobile user, both for hot desking within the enterprise and also to provide remote access at home, or on the road. The system allows several connections to the same desktop, providing an invaluable tool for collaborative or shared working in the workplace or classroom. Computer support within the geographically spread family is an ever popular use.
For the individual user, one common scenario is using VNC to help troubleshoot the computer of a distant less-technically-savvy relative. In other words, sitting at your desk in Baltimore, you could use VNC to take control of your relative's PC in California and show them how to install and use some new software package by actually doing it yourself.
A very common business application of VNC is in remote system administration, where it is used to allow administrators to take control of employee machines to diagnose and fix problems, or to access and administer server machines without making a trip to the console. VNC can also be used to provide a flexible hot-desking and road-warrior environment by allowing employees to access their office desktop and server machines from any machine in the company's offices or from other remote sites, regardless of the type of computers involved at either end.
VNC is widely used in educational contexts, for example to allow a distributed group of students simultaneously to view a computer screen being manipulated by an instructor, or to allow the instructor to take control of the students' computers to provide assistance.
Core Features
VNC Enterprise Edition is an enhanced version of the industry-standard VNC, developed for use in corporate environments and across the Internet. Designed and built from the ground up by the original inventors of VNC, Enterprise Edition provides robust and easily-administered security with a minimum of fuss.
The core Enterprise Edition features, common across all supported platforms, are as follows.
* Integrated Session Security provides protection from connection snooping, man-in-the-middle attacks and packet-tampering attacks, to name but a few.
o Server Authentication uses 2048-bit RSA keys to verify identity.
o Viewer Authentication supports both usernames and passwords of up to 256 characters each.
o Secure Communication with 128-bit AES—the experts' choice for high performance encryption.
* Platform-Native Authentication removes the need for separate VNC and system passwords. Users can access their desktops using the same credentials with which they log on to the system.
* One-Port HTTP & VNC allows VNC Server to serve VNC Viewer for Java and VNC sessions through a single TCP port, simplifying NAT and firewall configuration.
* Cross-Platform Interoperability with the other members of the VNC Enterprise family
