As the old saying goes, 'prevention is better than cure'; it is crucial to know how to counter wireless network threats and vulnerabilities before any harm can be done. With that being said, we have to know the type of wireless network attack in order to be able to protect it. Five commonly know network attacks are access control attacks, confidentaility attacks, integrity attacks, authentication attacks and availability attacks. Access control attacks attempt to penetrate a network by using wireless or evading WLAN access control measures. Confidentaility attacks attempt to intercept private information sent over wireless associations. Integrity attacks send forged control, management or data frames over wireless to mislead the recipient or facilitate another type of attack such as Denial of Service(DOS). Authentication attacks steal legitimate user identities and credentials to access otherwise private networks and services. The most well-known kind of such attacks is identity theft. Lastly, availability attacks impede delivery of wireless services to legitimate users, either by denying their access to WLAN or by crippling those resources.
