The Wireless Vulnerabilities and Exploit (WVE) database is a wonderful wireless security resource. The WVE is basically a clearing house for wireless vulnerabilities and exploits. It is similar to the Common Vulnerabilities and Exposure (CVE) database however the WVE focuses on wireless technology. Also the CVE database only tracks vulnerabilities where the WVE database tracks vulnerabilities and the exploits that can be used to attack those vulnerabilities.
When assessing the security of a wireless device this is one of the research tools I use to determine if there are any known weaknesses in that device.
