IEEE 802.11 Attacks and Defenses

Abstract

Protection of IEEE 802.11 networks means protection against attacks on confidentiality, integrity and availability. Possible threats come from vulnerabilities of security protocols. The rapid growth in the use of wireless networks attracts the attackers as a target. Wireless traffic consists of management, control and data frames. An attacker can manipulate these frames that affect the data integrity, confidentiality, authentication and availability. A real Wireless Local Area (WLAN) testbed setup is proposed for performing the vulnerabilities of well-known attacks pertaining to IEEE 802.11 network and monitoring the analysis of packets. Based on these categories of vulnerabilities and threats, Confidentiality Attack: Evil Twin Availability Attacks: Deauthentication Disassociation and Café Latte and Authentication Attack: Dictionary attack are conducted through demonstrations in a real environment by using proposed setup.
