System and method for detecting free and open wireless networks

摘要

A system, method, and program product is provided that passively detects the existence of wireless networks in proximity to a wireless signal detector. A determination is made as to whether the detected wireless networks are encrypted or unencrypted. For those wireless networks that are unencrypted, a restriction level that applies to the unencrypted network is identified. The user is then notified when an unencrypted and unrestricted wireless network is detected.
