Definition
A jump server is a secure computer that bridges two or more networks, enabling users to connect to one network and move to another. They are used to manage and control network access, especially for public networks.
In cybersecurity, a jump server is similar to a VPN, which creates a secure connection between the user and the server. However, the jump server adds a layer of security, like auditing features.
Jump Server Use Cases
- Security management: It is a centralized point for controlling authentication and access, minimizing the attack surface.
- Administrative access: In business settings, engineers or system administrators use it to reach servers behind firewalls or within secured networks.
- Audit trails: With all connections passing through the jump server, it can log activities, providing an audit trail of system access, which can help with auditing and tracking purposes.
