- Security technologies for wireless access to local area networksPublication . Faraj, Khaldoun Esmaeil; Barradas, ÁlvaroIn today’s world, computers and networks are connected to all life aspects and professions. The amount of information, personal and organizational, spread over the network is increasing exponentially. Simultaneously, malicious attacks are being developed at the same speed, which makes having a secure network system a crucial factor on every level and in any organization. Achieving a high protection level has been the goal of many organizations, such as the Wi-Fi Alliance R , and many standards and protocols have been developed over time. This work addresses the historical development of WLAN security technologies, starting from the oldest standard, WEP, and reaching the newly released standard WPA3, passing through the several versions in between,WPA, WPS, WPA2, and EAP. Along with WPA3, this work addresses two newer certificates, Enhanced OpenTM and Easy ConnectTM. Furthermore, a comparative analysis of the previous standards is also presented, detailing their security mechanisms, flaws, attacks, and the measures they have adopted to prevent these attacks. Focusing on the new released WPA3, this work presents a deep study on both WPA3 and EAP-pwd. The development of WPA3 had the objective of providing strong protection, even if the network’s password is considered weak. However, this objective was not fully accomplished and some recent research work discovered design flaws in this new standard. Along with the above studies, this master thesis’ work builds also a network for penetration testing using a set of new devices that support the new standard. A group of possible attacks onWi-Fi latest security standards was implemented on the network, testing the response against each of them, discussing the reason behind the success or the failure of the attack, and providing a set of countermeasures applicable against these attacks. Obtained results show that WPA3 has overcome many of WPA2’s issues, however, it is still unable to overcome some major Wi-Fi vulnerabilities.
