Java supports creating of ServerSocket(s) in more than one way. This is an important aspect of security.

SSLServerSocketFactory is a secure way of achieving this. This ensures that the socket is encrypted and it is not an easy target for an attacker.

Code snippet:

*/import java.io.*;import java.net.*;import javax.net.ssl.*;public class SecureSocket{   ServerSocket serverSocket;      public static void main(String args[])   {      SecureSocket secureSocket = new SecureSocket();      secureSocket.proceed();   }      private void proceed()   {      //Creating a secure socket using SSLServerSocketFactory      try      {         serverSocket = SSLServerSocketFactory.getDefault().createServerSocket(8700);      }      catch(IOException ioe)      {         ioe.printStackTrace();      }   }}
