Abstract
In the provided article wireless local area networks were probed. In case of design and maintenance of wireless networks it is necessary to pay the big attention to information security. There are a lot of technical issues of networks. This article is devoted to the analysis of methods of safe information transfer on the local and corporate area networks. It is offered to carry out scanning of a radio-frequency range of several access points for detection of cryptography techniques. The analysis showed that encoding WPA2 Enterprise is the most reliable today in corporate networks, EAP authentication type is often used. Protocols of protection of wireless networks EAP-TLS/TTLS are included into the standard 802.1x and use the infrastructure of public keys for a data interchange between the client and RADIUS. The combination of these keys provides reliable protection of wireless local area networks. Digital certificates should be created for each Wi-Fi device. It is a long process, therefore certificates are usually used only on the Wi-Finetworks requiring the maximum protection. At the same time it is possible to withdraw easily the certificate and to disable the client. In design of Wi-Fi networks the principles of safety are often broken, the same mistakes are made. Research showed that it is necessary to restrict a possibility of connection of third-party devices to a local computer network, for example, using authentication according to the protocol 802.1x. The protocol is built into operating systems and special software packages. Operation mode 802.1x is the most widespread and reliable. Here the authenticator resolves or forbids access to a network.
