Will WPA3 really provide Wi-Fi security at a higher level?

摘要

The nature of wireless network transmission means that an attacker does not have to be in the place where sucha network is deployed. It is possible to sense, capture and analyze network traffic from a distance without being detected.If the network is not well secured, discovering of the information is not a problem. Security is one of the major concernsregarding Wi-Fi other than performance or range. Security should be one of the primary factors to consider whenplanning a wireless network. However, a lot of people who use it or intend to use it are not aware of the problem.Dictionaries with passwords, fake access points (AP) or backdoors in the routers’ software are just some of the methodsused by attackers. Recently, a lot of methods have been related to socio-technical activities. In such cases, even securesystems can be vulnerable, because the target of the attackers is not focused around a technical feature but on people’sbehaviors. This is a case, because, “human factor” is very often the weakest element in the security chain. Therefore, theaim of this paper is to raise the security awareness of users and protect wireless networks against adversary attacks.Particular attention is paid to the severity, possible targets as well as defense strategies against intruder’s actions. In thiscontext, new WPA3 protocol promises to make it harder to break the into a Wi-Fi network. The article also presentsa discussion on new features of WPA3 and their impact on improving the security of Wi-Fi networks.
