Overview of WLAN security Vulnerabilities

Abstract

The development of wireless network systems has made it easier to communicate using electromagnetic waves, which has led to the removal of the main obstacles to portable communication. In the modern day, where every device—from personal computers to business equipment—uses a variety of coding techniques to share data on the network, wireless networks play a crucial role. However, because wireless networks use the air as a communication medium, they must deal with extra security risks. In this study we outline the security options for WLANs. These security mechanisms are Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA) and 802.11i (WPA2). Our aim is to discover weaknesses in the WLAN security protocol through an attack that can be performed in the system. a description of their operation, structure, and algorithmic framework. and successfully launched attacks against WEP and WPA2 networks in an effort to discover real time vulnerabilities. Three laptops with wi-fi capabilities were used to carry out the attacks in an ad-hoc network [12]. We start with the WEP protocol, which makes use of the weak and readily decipherable RC4 algorithm. Next, we list a few of its shortcomings. Then, as an enhanced version of WEP with some weaknesses, we have WPA. WPA2 vulnerabilities explain, at last.
