A method for controlling propagation medium local area network in order to protect

Currently, the most common standard for the construction of local area networks (LANs) is the IEEE 802.3 (Ethernet). Common medium propagation networks Ethernet, using the mechanism of exchange of broadcast network frames, is a platform for the implementation of privacy threats not only using special tools, but also by unauthorized connection to the propagation medium standard network equipment supporting the hardware or software level mode "disorderly" capture (promiscuous mode) network frames. The "random" capture network frames used in the protocol analyzer aimed at monitoring and diagnostics of local networks.
