SECURITY OF INFRASTRUCTURE MODE OF IEEE 802.11 WIRELESS NETWORK STANDARD

Wireless networks are increasingly used today and have become the de facto standard for connecting computers while at the same time offering simple implementation with reduced costs, satisfactory bandwidth speeds and greater mobility of users. Wireless communication provides users with greater mobility, and therefore faster and easier access to sources of information. When talking about wireless local area networks, a particularly important issue is that of security. Wireless networks are the least secure part of the wired local area network (LAN) because they use air as the medium for transmission, and in so doing the network becomes available outside the organization in which it is used. Security algorithms (encryption) prevent the possibility of unauthorized use of the network, but they do not offer one hundred percent security. This paper will present an overview of security technologies regarding infrastructure mode of wireless network and make recommendations for secure mode. The paper provides an overview of the methods of infrastructure security with regard to the IEEE 802.11 WLAN standard.
