What is the primary purpose of a jump server in a secure network?

The primary purpose of a jump server, also known as a jump box or bastion host, in a secure network is to act as a management console. It serves as a secure intermediary that allows system administrators to access and manage devices and servers in a more secure manner. By using a jump server, network administrators can limit direct access to critical servers, thereby reducing the attack surface. The jump server typically has stringent security controls in place, such as monitoring, firewall rules, and limited user access, which helps in maintaining a secure environment for administrative functions.

This centralized point of management means that all administrative tasks can be performed from a controlled location, enhancing security and making it easier to log and audit access and activities. Thus, the jump server plays a key role in maintaining the integrity and security of sensitive areas of the network by acting as a funnel for administrative connections.
