Being a hacker requires a bit more knowledge than TCP/IP. To build upon your analogy, TCP/IP is more like the path to your house. If offers no security beyond what you gain by mounting watch on your doorstep. Every open port on your server is like a door or a window. The protocol carried by TCP/IP and recognized by the server application listening on the open port is the lock on the door or window. Your login/credential is the key to the door. Hackers are like thieves trying to break into your house. A thief knows about various types of locks, doors and windows. He knows that some windows break if a pressure is applied on the upper corner opposite the hinges. Such a type of lock is easily defeated by drilling just below the barrel. Some kind of door is best attacked by breaking through the lower panel, and so on. A hacker can find your server the same way a thief can find your house. He just walk around and look at what may be a worthwhile target. A hacker knows about the protocols and server applications. He knows their strengths and weaknesses and will attack where it is easier when he sees an opportunity. That is the reason you must update your server on a regular basis. It removes old safety measures the hackers know how to break. And when the house is properly secured, a thief may knock at the door and sweet talk the owner into letting him in. Hackers do that too :-) Frederic -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
