Segurança em redes wireless IEEE 802.11 e suas vulnerabilidades

Abstract

This work presents an analysis of the security protocols of the IEEE 802.11 standard, which is presented the characteristics of each protocol, as well as your weaknesses. To discuss the security protocols of IEEE 802.11, it was established a knowledge base about them showing their structure and vulnerabilities. The IEEE 802.11 security protocol is presented progressively, working with other protocols, mechanisms and standards existing in each protocol, mechanisms and standards existing in each protocol, as well as their vulnerabilities that are exposed to prove the danger that each vulnerability represents for users, to maintain the importance of security research for its continued development. Finally, the vulnerabilities related to the authentication of the WPA and WPA2 protocols presented, which proved their flaws. As a result, it was found that even with the IEEE 802.11 standard defining security protocols it still requires that users, whether residential or commercial, understand the ways to protect of each of the protocols.
