Nowadays, Wi-Fi technology is used everywhere in the world: in the offices of large companies, public places and in simple home premises. However, the use of a public transmission medium leads to the possibility of various attacks. This article discusses attacks such as authentication failure and Address Resolution Protocol inject. The considered attacks have shown high efficiency and danger for wireless networks. In this connection, methods of detection and protection against them were proposed. Methods. At the first stage, the concept of how attacks work, their main idea and purpose, were analyzed. At the subsequent stages, for testing, a laboratory stand was created, on which they were simulated. In the course of the experiments, the effectiveness of attacks was found out, and the main phases of attacks and the elements that contribute to their detection were graphically reflected in the article. Main results. As a result of the work done, it was possible to isolate attack vectors and identify their accompanying anomalies. Based on the research materials, mechanisms for detecting and preventing the attacks under consideration were developed. The practical part. All theoretical and experimental materials collected in the article can be used in detecting and preventing attacks on wireless networks by network administra-tors and information security specialists.
