What Is Wireless Security

The new standard in wireless networks—802.11g—offers speed, security, and performance.  It is also the most widely employed standard in corporate internal wireless LAN networks.  You can transfer data at up to 54Mbps using 802.11g (which is five times the speed of older 802.11b wireless networks).  And wireless LANs provide some obvious benefits: they always provide on-network connectivity, they do not require a network cable, and they actually prove less expensive than traditional networks.  But to take advantage of these benefits, your wireless LAN needs to be properly secured.  This extra level of security complexity adds to the challenges network administrators already face with traditional wired networks.  This article covers the types of attacks wireless networks encounter, preventive measures to reduce the chance of attack, guidelines administrators can follow to protect their company’s wireless LAN, and an excellent supply of online resources for setting up a secure wireless network.

Ultimately, security is everybody’s business, and only with everyone’s cooperation and consistent practices will it be achievable. Wireless security is a work in progress, so it is essential to administer a wireless network so that it becomes more and more secure. And with more organizations focusing strongly on wireless security, we can only expect to see many more secured wireless networks in the future.
