This essay will define a “denial of service” (DOS) attack and explain the steps involved in an attack. The new type of DOS attack using phone lines will be the focus of the research provided in this essay. Denial of service attacks can affect both business and financial operations of an individual or a business. The impact of the attack both on financial and business operations will be outlined. The measures a person or business can put into place in order to avoid these attacks will be discussed. If a business or individual is still subject to an attack certain actions can help to minimize the losses caused by the intrusion. Actions to take in the event an attack is not avoided will be suggested.
