Radio receiver net (WLAN) applied science embodies the most bolted prospering segment of the communications securities industry.
Harmonizing to Gartner Research, worldwide shipments of WLAN units are forecasted to grow at an annual rate of 42% through 2007.
The major driver fueling this growth is the strong return on investment afforded by much lower installation costs, higher availability, and mobile data connectivity. Another significant advantage of WLAN technology is that there is no “killer app” required to deploy wireless networks. WLAN components hoopla into the extant Substructure as plainly as extending a phone line with a wireless phone. Unlike traditional network technology adoption that starts with enterprises and moves to the SOHO and home markets as the technology matures, WLANs are being adopted in the opposite order. While galore Tummies and lines of work are taking over wireless LANs, the SOHO and home users are adopting WLANs at a much faster pace. By removing the need to wire a network in the home, the cost of adoption and benefit of mobility within the home and low cost of components make wireless networking a low-cost and efficient way to install a home network. This segment of the market is much less aware and concerned about the security implications associated with wireless networks. At the same time, wireless adoption within the corporate and medium-sized businesses has been severely inhibited by security concerns associated with placing sensitive corporate data over the air. While home users are less aware and less concerned about the security implications associated with wireless networks, WLANs have struck a nerve with security conscious IT departments. Until recently, there has been no straightforward, cost effective way to deploy wireless security. IT departments have been forced to either forbid the deployment of wireless networks, overlook the security concerns, or install costly VPN solutions to build protected data tunnels between each wireless user, and the core network. This paper discusses the 3 layers of wireless security and the options available for securing the network:
• Physical layer encryption, including WEP which has proven ineffective against hackers and intentional
intruders;
• 802.1X standards-based security which provides cost effective, easy to use network security; and
• VPN-based security for the most security conscious requirements.
