Abstract
Some embodiments of the invention are directed to increasing security and lowering risk of attack in connecting automatically to networks by enabling client devices to verify the identity of the networks by, for example, confirming the identity of networks and network components such as wireless access points. In some embodiments, a client device may maintain a data store of characteristics of a network—including, for example, characteristics of a wireless access point or other portion of the network and/or characteristics of a connection previously established with the wireless access point and/or network. Stored characteristics may include characteristics other than those minimally necessary to identify a wireless access point and/or wireless network. The stored characteristics may be compared to known good characteristics of a network (including characteristics of a wireless access point or other portion of the wireless network) prior to connection to the network to determine whether the characteristics match.
