Wireless networks are based on IEEE 802.11 standards defined by the Institute of Electrical and Electronics Engineers (IEEE ) for ad hoc networks or infrastructure networks. Infrastructure networks have one or more access points that coordinate the traffic between the nodes. But in ad hoc networks, there is no access point; each node connects in a peer-to-peer way.
Two types of vulnerabilities can be found in the Wireless LAN. One is poor configuration and the other is poor encryption. Poor configuration is caused by the network admin who manages the network. It may include a weak password, a lack of security settings, use of default configurations and other user-related issues.
Poor encryption is related to security keys used to protect the wireless network. These vulnerabilities exist because of issues in WEP or WPA.
