How to resist this kind of attacking behavior is always the key point of the domain of the information security. And the port scanning draws peoples attention more and more. Port scanning is a usual method which is used by the hacker to collect the information of the target main processor. In order to deal with the invading behavior of the Internet effectively, it is very useful and necessary to work on the port scanning. When an attacker attacks to a target, he or she will firstly gets some basic information about the target, and the port scanning is one of the most simple and important methods which can scan the opening Port of the target machine to make sure the offering service made by the target machine, and it is a preparation to the next attacking. The port detecting seems more and more important referring to the port scanning. As an important task of the secure technique of Internet, the port detecting is of great significance. In this thesis, it firstly elaborates the basic principles and usual methods of the port scanning. On this basis, it then designs a program which can scan the Port of the Internet, and assess the opening situation of the target main processor, and the other program which begins on capturing and analyzing the information packet of Internet, and then assess whether there is a behavior about port scanning through statistic analyses. Lastly, it demonstrates and analyses the technology of port scanning and port detecting from the viewpoint of attacking and resisting.
