Abstract: This document is a study of the Wi-Fi networks, and it pretends to raise the reader's awareness of the vulnerabilities of these networks due to their insecure nature, that makes an attack on their network very easy if proper protocols and measures are not followed. This document is suitable for readers who do not have prior knowledge of networks, as well as for those with average knowledge who want to audit their network to know their weaknesses and make it more secure. To do this, the document is divided into three parts, first, there is a contextualization of the Wireless networks where the reader can understand its main elements and architecture, secondly, the different protocols that exist today are explained (WEP, WPA and WPA2 ) ending with a comparison between them, finally, in the practical part different attacks are carried out so the reader can protect himself against them, giving security advices that can be applied on his own networks. Finally, it is concluded that the protocol that must be used is WPA2, demonstrating the importance of encryption in these networks. It is also concluded that the default password of the access point must be changed and the importance of incorporating strong passwords. It is also recommended to always update the access points and devices on a network, in addition to taking extra security measures such as MAC filtering. Finally, several tools with which the reader can perform network audits are discussed.
