The automaton modeling of typical network attacks

Network security is one of the most important research fields among information security techniques. Most problems of network security are often caused by network attacks. In order to ensure network secure running it is very necessary to analyze and research the procedure of network attacks. In this paper, the formal method is researched and automaton theory is used to describe the procedure of network attacks. The state transform diagrams of some typical network attacks are given. Different state transform diagrams are used to describe models for various network attacks and these models can be combined flexibly so as to describe complicated attack behaviors. This formal method for describing network attacks provides an effective approach for researching the mechanism of network attacks.
