Advanced Features with a Jump Host

Why use a Jump Host?

• A jump host is located in a DMZ or (demilitarized zone) and therefore it can access servers at customer sites via the Internet. Local servers quite often are excluded from Internet access for security concerns.
• Jump hosts are used in order to store files temporarily and to forward them to the final destination Depending on the transfer direction, this can either be a local server or a server at a customer site.
• A typical jump host architecture is shown in the following diagram:

Security Considerations

• Jade YADE does not store its configuration data on the jump host. Instead, the Jade client YADE Client hands over its parameterization to the jump host on-the-fly where it is used by an additional Jade client YADE Client instance.
• Files stored temporarily on the jump host are removed on completion of the transfer.
• No log output is created on the jump host and therefore private data is not stored on that host.
