  • Socks protocol provides a framework for client-server applications in both the TCP and UDP domains to conveniently and securely use the services of a network firewall
  • The basic purpose of the protocol is to enable hosts on one side of a SOCKS server to gain access to hosts on the other side of a SOCKS Server, without requiring direct IP-reachability.
  • The protocol is conceptually a “shim-layer” between the application layer and the transport layer, and as such does not provide network layer gateway services
  • SOCKS includes two components, the SOCKS server and the SOCKS client
  • When an application client needs to connect to an application server, the client connects to a SOCKS proxy server. The proxy server connects to the application server on behalf of the client, and relays data between the client and the application server. For the application server, the proxy server is the client.
