Jump Server

A jump server, also known as a jump host or pivot server, is a secure intermediary server used to access sensitive or restricted resources in a network. This server acts as a control point that enforces access controls and enhances security by providing a single entry point to reach other servers or devices within a network. Typically, it is used in environments where administrators need to manage and maintain various servers and systems without directly exposing them to the public internet. Users first connect to the jump server, and from there, they can “jump” to other servers with the necessary permissions, reducing the attack surface and ensuring a more controlled and secure access mechanism.
