Denial of service is a constant concern in the world of networking. By DoS attack, the authors mean any effort to \"Prevent or impair the legitimate use of computer or network resources\", interrupting or delaying services which can cause a node or an entire network to become unavailable. The industry standard for handling DoS attacks includes a three-step process of protection, detection and reaction. Protection, however, is the best defense because if a system is not protected, or a network is not prepared, then detection is more difficult and reaction can be more costly.
