You are a member of the security team in the IT Infrastructure department at a manufacturer. You have received a ticket from the network architecture team who have requested your approval of a proposed network change. The change is to replace a network device that allows internal servers to make requests to the internet without external systems being able to determine what internal server made the original request. What type of system is being changed?
Correct Incorrect Unanswered Report Issue Answer Description
When a user or system wants to make a request to another system without revealing it's identity a proxy can be used. Proxies act as intermediaries to transmit data between systems. The most common use case is to route web requests from internal users and devices through a reverse proxy so that external web servers cannot tell which internal user or device made the original request.

In computer networking, a proxy server is a server application that acts as an intermediary between a client requesting a resource and the server providing that resource. It improves privacy, security, and performance in the process.
Instead of connecting directly to a server that can fulfill a request for a resource, such as a file or web page, the client directs the request to the proxy server, which evaluates the request and performs the required network transactions. This serves as a method to simplify or control the complexity of the request, or provide additional benefits such as load balancing, privacy, or security. Proxies were devised to add structure and encapsulation to distributed systems. A proxy server thus functions on behalf of the client when requesting service, potentially masking the true origin of the request to the resource server.
