Which device can be used to manage access to a private database server from a public-facing web server?

The jump box, also known as a jump server or bastion host, is specifically designed for securely managing access to private network resources, such as a database server, from a less secure environment, like a public-facing web server. By using a jump box, an organization creates a controlled entry point that can have enhanced security measures, such as strict access controls, logging, and monitoring.

When administrators need to reach the private database server, they first connect to the jump box, ensuring that direct access to critical internal resources is restricted. This adds an additional layer of security because the jump box can be designed to expose only the necessary management tools and services to the web server, while keeping the internal database server hidden from direct external access.

Other options, such as VPNs and proxy servers, serve specific purposes but do not typically function solely as management access points. VPNs create secure tunnels for encrypted communication over the internet, which could allow access to the private database but don’t necessarily manage that access in an administrative capacity. Proxy servers can act as intermediaries for requests from clients seeking resources from other servers, but their primary function is not limited to direct management access. Load balancers distribute incoming traffic across multiple servers to ensure system reliability and performance, rather
