... problems
• There are several known weaknesses in the structure of WEP
encryption
• WEP shared secret is useless when it’s common knowledge
• WEP key exchange is not yet a defined standard, different vendors
have implemented their own solution that usually are not interoperable.
• MAC address can be faked very easily => additional authentication is
required
• Radio DoS attacks may only be prevented by legislation, radio
interference from other devices cannot be prevented, only avoided
• The only methods to authenticate radio network on non-IP level to user
are network id (essid) and the possible shared secret
• Replay attacks may be prevented to some extent with WEP but the
network is as vulnerable as every other IP network
