• W85104039 abstract "In Wi-Fi networks was identified the lack of rules as being a problem, actually there is no rule that prevents the network administrator from setting the same Service Set IDentifier (SSID) that the neighborhood network has already set, well maybe only the rule good sense. Other of the problems that was identified, consisted in bad administrative measures by the station users, that prefer to don’t install Certification Authority (CA) certificate, and prefer instead to ignore the verification of the CA certificate. This fact alone constitute an insecure autentication, and makes possible to the station to suffer various kinds of attacks. Was based on the problems above mentioned that this work was initiated, it has the theme “Autenticacao de redes Wi-Fi recorrendo ao DNSSEC”. In this sense, the main guideline objective of this work is to implement and design a security solution that allows stations 802.11 to correctly identify Wi-Fi networks with authentication servers in order to prevent attacks from forged networks without the user having to enter any information beyond the SSID. The present work, consists in two parts, in the first part the Wi-Fi Protected Access (WPA) supplicant was altered and configured to authenticate in Wi-Fi networks with a global SSID. In the second part, the needed changes were performed so that a ScalSec authentication could occur, this will allow to verify the validity of the CA certificates using the Domain Name System Security Extensions (DNSSEC). The solutions were not radical, it must allow other authentication protocols occur, in a clean and safe manner. In order to achieve the second objective, various authentication protocols could had be chosen, but in this case, the choosed method was the EAP-PEAP, which uses during the authentication process, certificates, this guarantees the server validity to the user and also ensures the confidentiality of the transmited data. The problem with the currents solutions is the need of having a CA root certificate. Or the CA root certificate, is signed and validated by a trusted entities, which has its costs, or it has to be locally installed on all customers who want to use the service. Finally, in order to verify this new authentication approach a set of machines was setuped wich allowed to demonstrate and validate this solution. It was developed a set of scripts and programs that facilitate the configuration process, making it transparent to the network administrator." @default.
