Abstract—Wireless LANs widespread use is attributable to a combination of factors, including simple construction, employee convenience, connection selection convenience, and the ability to support continual movement from residences to large corporate networks. For organizations, however, the availability of wireless LAN means an increased danger of cyberattacks and challenges, according to IT professionals and security specialists. This paper examines many of the security concerns and vulnerabilities associated with the IEEE 802.11 Wireless LAN encryption standard, as well as typical cyber threats and attacks affecting wireless LAN systems in homes and organizations, and provides general perception of weaknesses for home and business users.
