Análisis de vulnerabilidades de protocolos de protección y autenticación inalámbrico para el aceso seguro en redes Wifi.

Abstract

Wireless networks are rapidly spreading, great comfort and advantages that these new technologies that many users creating connections have not been aware of the dangers they are exposed wireless networks (and not having a physical connection). Thus the excessive growth of wireless connections created the curiosity of many to try to interfere with these, achieving in many cases to obtain passwords, deny service or perform impersonations. This research attempts to solve one of the most common problems in wireless communication, security from attack by unauthorized persons in the use of WIFI networks. To this end, we conducted a brief study of the performance of commonly used security protocols, it immediately makes a comparative analysis of the vulnerabilities of protection and authentication protocols wireless WEP, WPA and WPA 2 PSK, WPA and WPA2 Enterprise in networks IEEE 802.11b, IEEE 802.1X with EAP-TTLS. After comparative analysis by security settings confidentiality, integrity, availability and authenticity provides an assessment of countermeasures against attacks associated with the vulnerabilities found. Eventually develops a reference guide for designing and setting up a secure WiFi network, with the protection and authentication schemes that provided the best performance in secure access to IEEE 802.11b networks.
