Since the first denial of Service (DoS) attack appears, DoS attacks cause significant financial damage
every year. The majority researchers focus on detection and respond mechanism of DoS, whereas limited progress has
been made in the details of DoS attacks. In this paper, we introduce Custom Audit Scripting Language (CASL) applied
to write simulation program for DoS attacks. Then we take a deep research in the methodology of DoS attacks and
simulate two typical DoS attacks in CASL. Additionally, recent trends of DoS attacks and problems associated with
defending against DoS attacks are also discussed. In short, our simulation attack programs can help examine the nature
of DoS attacks and find the corresponding countermeasures
