RSA Security Inc. conducted its annual survey of New York, London and Paris and found that more wireless hot spots are working to secure their networks but a fifth of corporate access points remain open.

In all three cities the percentage of hot spots protected by some form of encryption increased; London went from 76 to 81%, New York only grew from 75 to 76%, while Paris jumped from 78 to 80%. They also found that Wired Equivalent Privacy (WEP) is being replaced by Wi-Fi Protected Access (WPA), a much more secure method.

The number of businesses without adequate protection is a bit surprising considering what could possibly be at risk for these companies. London and Paris both had about 18% of their companies unprotected and New Yorkers topped the list with a full 21% of their businesses tempting fate.
