Abstract
A lo largo de este documento, se presentará lo que trata de ser un estudio acerca de los ataques de denegación de servicio basados en servidores DNS (Domain Name System). Con el fin de poner al lector en situación, en primer lugar, se llevará a cabo una introducción en la cual se revisa la situación actual en la que nos encontramos frente a este tipo de ataques, así como, se explicará brevemente en qué consisten y cuál es la finalidad que persiguen.
Posteriormente, se muestra la planificación llevada a cabo para conseguir lograr los objetivos propuestos, además de poner en situación acerca del marco legal y socio-económico que envuelve y afecta directamente al desarrollo del proyecto. Previo a la presentación de las pruebas realizadas y los resultados obtenidos, se lleva a cabo una descripción de las herramientas empleadas de tal forma que los lectores puedan hacer un seguimiento del estudio de una manera más sencilla y amena.
Adicionalmente, se muestran los diferentes diseños y prototipos elaborados, hasta que finalmente se llega al desarrollo final del entorno en el cual se llevarán a cabo las diferentes fases del estudio. Dichas fases se desarrollan de manera progresiva de tal forma que se consiga lograr una denegación de servicio para de esta manera observar su comportamiento. Finalmente, se expondrán las conclusiones obtenidas y se analizará si el estudio ha cumplido o no con los objetivos marcados al inicio de este. Valorando si el resultado obtenido es satisfactorio o no.
Throughout this document, it will be displayed what tries to be a study about Denial of Service attacks based on DNS servers. In order to put the reader in situation, first of all, be held an introduction in which we review the current situation of this kind of attacks, as well as briefly explained in what consists and what is the purpose pursued by them. Subsequently, it will be shown the planning carried out to achieve the different objectives proposed, in addition to study about the legal and socio-economic framework which surrounds and affects the development of the project. Preceding the results of the different tests carried out, a description of the different used tools is made so that readers can follow up the study in a simpler way. In addition, the different designs and prototypes developed are shown, until we finally reach the final environment in which the different phases of the study will be carried out. These stages unfold progressively so that a denial of service attack is accomplished so that we can monitor their behaviour. Finally, the conclusions reached will be displayed and it will be analysed whether the study has complied or not with the objectives set at the beginning of it. Assessing if the result is satisfactory or not.
