WiFi has been around for several years now, and it is currently an established and accepted technology. Some WiFi spots allow users to access the Internet for free on public places, such as airports, libraries, hotels and pubs, which is great. There are several websites that provide a list of free WiFi spots, such as wififreespot.com, wi-fihotspotlist.com and hotspot-locations.com.
It's also on the news that WiFi while travelling by plane will be available pretty soon. People is getting used to having WiFi connectivity at their convenience everywhere.
However, the average Joe may not be aware of the security issues surrounding this technology: there are WiFi exploits available through Metasploit; several Security Incident Response Teams, such as FrSIRT, have released advisories reporting vulnerabilities; and every now and then, a survey shows how WiFi users do not control access to their network. Meanwhile, wardriving (and even warflying) is a fairly common practice.
So, it seems it's time to wake up and smell the coffee: you should secure your WiFi network or connection.
Some months ago, PandaLabs released a document on this matter. It discusses the technical characteristics of WiFi on a security level, the most widely used standards, the attacks they must head off and the measures available to users to secure this type of network.
