A Survey of Denial of Service Attacks and it’s Countermeasures on Wireless Network
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 5
Abstract
Wireless networks are popular among the Laptop user community today because of the mobility and ease of use. People working through wireless connection must be aware of the surroundings due to the various types of attacks made by the intruders. One of the major attacks in wireless 802.11 WLANs is Denial of Service attack (DoS). Even though the users protect their systems with Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA) security protocols, DoS attack is still prevalent. This paper makes a survey on different types of DoS attacks and their countermeasures on the infrastructure networks which are based on the Access Points (AP). In this paper, the main attacks called eauthentication and Disassociation Flooding DoS attacks are studied through experiments and the possible solutions are recommended. This paper also studies the vulnerabilities due to rogue access point, null data frames and Access Points. The various solutions suggested for this problem like Pseudo randomized sequence number based solution to 802.11 disassociation, Pseudo random number based authentication to counter DoS, Dual authentication for fast handoff in IEEE 802.11 and Letter Envelop Protocol as a light weight solution are studied and reported.
