Security in Wireless Networks: Analysis of Wi-Fi Security and Attack Cases Study

Wireless networks are now an integral part of many People's Daily lives. In particular, technical terms such as Wi-Fi Fidelity have long been known nouns. Although the implementation of the physical and link layer of Wi-Fi is quite complex, due to its popularity, the network attacks based on Wi-Fi are frequent. It can be said that the threat from wireless networks is omnipresent. Therefore, it is necessary to study and analyze Wi-Fi-related network attacks. The purpose of this paper is to find and analyze the preventive measures of wireless network security threats by studying and analyzing the network attack behaviors related to Wi-Fi to improve the security of the wireless network. The research methods of this paper are case study and report. First, a correct understanding of the enormous impact of this threat was formed by studying actual cases of wireless network attacks. Then, through the analysis of the attacker's means of attack and protocol security vulnerabilities, design defects, etc., will guard against wireless network security threats to face technical problems and legal issues clear. Finally, practical solutions to these threats proposed.
