Proxy server: It is a server which acting as an intermediary between the internal and external networks, showing all outgoing and incoming traffic. At the Application layer of the OSI model, security was managed by the proxy server. When compare to all other services, proxy server only provides low-grade security but it can help to prevent an attack on internal network resources such as web clients and web server.
