CM4000 Secure Desktop Tunneling

CM4000
Secure Desktop Tunneling is an easy to use remote management tool that allows both end users and administrators to securely access and take remote control of any computer running VNC or Microsoft's Remote Desktop. The new tool couples Remote Desktop Protocol (RDP) and the popular VNC with the trusted open source SSH tunneling protocol, to significantly improve productivity and security for companies accessing their remote offices, or remotely accessing their data centers.

Remote access, management and troubleshooting

Opengear’s Secure Desktop Tunneling enables remote users and administrators to securely access Windows, Linux, Mac, AIX, HP-UX, Solaris and UNIX computers. The remote administrator can manage these computers and the data center (remotely upgrading server operating systems, rebooting the machines, viewing BIOS information from booting servers before their OS is loaded etc). The remote user can connect to an office computer and have access to all of the applications, files, and network resources (just as though they were in front of the computer screen at work).

 
 
Opengear bundles the Secure Desktop Tunneling tool with its console server and secure device server remote management hardware products. So Opengear's CM4000 desktop and rack-mount appliances now provide secure remote VNC and Remote Desktop access, while also giving administrators the tools to remotely monitor and administer their networks and servers over the console ports. The administrator has the troubleshooting tools to console manage UNIX basedservers; and securely access EMS in Microsoft Windows Server 2003. CM4000 also provides secure out-of-band access; so these remote computers and network appliances can be reconfigured and power cycled, even if the main internet data pathway is down.

Secure SSH Tunnels protect VNC and Remote Desktop

Secure Desktop Tunneling implements SSH tunneling, also known as SSH port forwarding, the process of forwarding selected TCP ports through authenticated and encrypted tunnels. It is generally recognized that while VNC and RDP are secure enough to use on a firewall protected private network, they are not robust enough for use directly over a public network. Secure Desktop Tunneling securely tunnels the VNC and RDP sessions from the remote user through to the CM4000 over any broadband (wireless, ADSL, cable) Internet connection; or over the enterprise private network, or even over a direct dial-up or ISDN modem connection. The CM4000 then forwards these RDP and VNC sessions to the computer being accessed through the local TCP/IP network or through the computer’s serial COM port.

 
 
VNC access generally allows access to the whole computer, so security is imperative. VNC uses a random challenge-response system to provide the basic authentication to connect to a VNC server. This is reasonably secure and the password is not sent over the network. However, once connected, all subsequent VNC traffic is unencrypted. So a malicious user could snoop the VNC session. Also there are VNC scanning programs available, which will scan a subnet looking for PCs which are listening on one of the ports which VNC uses. Similarly security with Microsoft’s Remote Desktop is paramount as anyone who has access to these administrative features can control the server. You can configure Remote Desktop traffic to be all encrypted, however its authentication is weak so it is susceptible to man in the middle (MITM) attacks. The solution is to tunnel all RDP and VNC over a SSH connection, thereby ensuring all traffic is protected by strong authentication and encryption.

No more hostile branch office sites and SMB customer sites

With its Secure Desktop Tunneling and its rich set of console management features, the CM4000 is the solution for off-site administration. No longer do enterprises with large distributed networks and branch offices need to regard their remote locations as hostile environments. Opengear now offers them a secure affordable solution for remote access to these sites, without the complexities of implementing full enterprise wide VPN solutions. The administrators controlling these networks can implement out-of-band remote management of the servers and network devices at these sites, and embrace them within the enterprise managed network (without the prohibitive costs of installing legacy KVM over IP solutions). They can also now administer their enterprise data centers after-hours; with a tool that lets them remotely manage from the application layer, right down through the operating system bring-up and boot level, to hardware reset.

Similarly the VAR/SI support manager now has the tools to help their SMB customers from afar. Opengear enables them to proactively manage the servers, power facilities, network equipment and storage devices at their customers' remote sites. No longer are they limited to being just reactive. And in event of trouble (or disaster) they can offer rich out-of-band recovery facilities (that would usually only be found in a large data center) and save the costs of on site repair. Best of all, they can make money, by offering their customers a truly top quality service package.
