System(IDS) hasn't Protection capability for various security attacks perfectly. Because, It is probably affected by IDS's workload caused by treating all kind of the characteristics and attack patterns of system and can't probe all of the attack types being intelligently different with attack patterns. In this paper, we propose a new taxonomy criteria about DoS(denial of service attacks) to make more efficient and new real time probing system. It's started with an idea that most of the goal oriented systems make the state of system operation more unambiguous than general purpose system. A new event caused the state of the system operation to change and classifying a category of the new events may contribute to design the IDS.
