Abstract
Como objetivo de mi proyecto pretendo dar a conocer a cualquier persona, empresa o institución que posea un Sistema de red inalámbrica los peligros que conlleva tener un sistema que no esté controlado y debidamente asegurado. En la documentación que voy a aportar quiero expresar la verdadera importancia y el auge que están teniendo las redes inalámbricas. Con el paso de los días podemos ir observando como estas, van incrementando tanto en restaurantes, centros comerciales, empresas, universidades, etc. Con las redes inalámbricas, lo que se pretende es tener las mismas funcionalidades que las redes cableadas, pero con un menor coste, mayor elasticidad y ligereza. Por otro lado voy a mostrar la topología y el modo de funcionamiento básico, con esto se va a comprender mejor porque, para la instalación de una red inalámbrica, a pesar de tener numerosas ventajas, estas presentan un problemas de seguridad, que solventaremos utilizando mecanismos de cifrado para garantizar la confidencialidad. Analizaremos los diferentes tipos de ataques (tanto pasivos, como activos), los métodos para captar redes inalámbricas inseguras, la utilización de herramientas para descifrar redes. Comprobaremos en detalle los diferentes mecanismos de cifrados WEP (Wired Equivalent Protocol), WPA (Wi-Fi Protected Access), WPA2, mecanismos de filtrado de MAC SSID, sistemas IDS (Sistemas de detección de intrusos), etc. Para finalizar una vez realizado el análisis anterior trataremos de dar una serie de pautas que nos ayudaran a mantener la seguridad de nuestra red inalámbrica y a realizar un diseño óptimo de la red. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Like aim of my project I want to inform any person, company or institution that has a wireless network system of the dangers of having a system that is not controlled and adequately protected. The documentation that I will bring I want to express the true significance and the boom being experienced by wireless networks. With the passage of time we can be observed how this one is growing up in restaurants, shopping centers, universities, etc. With the wireless networking, the aim is to have the same features as wired networks, but with a lower cost, greater flexibility and lightness. On the other hand I will show the topology and basic operating mode, with this is better understood why for the installation of a wireless network, despite having numerous advantages, they present a safety problem, but if we use encryption mechanisms, we solve to ensure confidentiality. We will analyze the different types of attacks (both passive and active), the methods to capture unsafe wireless networks, the use tools to crack networks. We will check in detail the different mechanisms of encrypted WEP (Wired Equivalent Protocol), WPA (Wi-Fi Protected Access), WPA2, MAC filtering mechanisms SSID, IDS (intrusion detection systems, etc.). To finish when the above analysis are ended, we will try to give a set of guidelines to help us maintain the security of our wireless network and to an optimal network design.
