What is a Jump box in terms of cybersecurity?

A jump box, also known as a jump server or a bastion host, is a special-purpose computer on a network that is used to securely manage and access other systems within the network.

The main purpose of a jump box is to provide a controlled and secure way for system administrators to access other servers or devices on a network. Instead of directly accessing the servers or devices from their own computers, administrators log in to the jump box first, and then use it as a gateway to connect to other systems.

Using a jump box can help to improve network security by reducing the attack surface and controlling access to sensitive systems. By limiting access to a single, centrally-managed system, administrators can monitor and control user activity more effectively, and minimize the risk of unauthorized access or data breaches.

Jump boxes are commonly used in large enterprise networks, particularly those that are segmented or geographically distributed. They may be configured with additional security measures, such as two-factor authentication or access controls, to further enhance their security.
