Jump Host

Noun · Security & Infosec

Definitions

  1. A system used as a secure stepping stone to access hosts in another network segment that are not directly reachable. A jump host is functionally similar to a bastion or jump box, but the term often emphasizes the connectivity role rather than the hardening details.

    In plain English: A host used as an access stepping stone into another network segment.

    Example: "Contractors had to VPN into the jump host before they could SSH to the private build servers."
