Wireless Security: Locking Down Your Wi-Fi

There are many ways to secure wireless networks. Unfortunately, not all of them are very secure. In a series of articles, IT Hub’s Larry Loeb dissects the encryption schemes and other security features used with Wi-Fi (IEEE 802.11) networks, and provides tips on implementing them as part of your organization’s wireless network defenses.
