What is a WEP key?

A WEP key is a user defined string of characters used to encrypt and decrypt data.

Can the SSID be encrypted?

WEP, the encryption standard for 802.11, only encrypts the data packets, not the
802.11 management packets; however, the SSID is in the beacon and probe
management messages. The SSID is not encrypted if WEP is turned on. The SSID is
transmitted over the air in clear text. This makes obtaining the SSID easy by sniffing
802.11 wireless traffic.
By turning off the broadcast of SSID, can someone still
sniff the SSID?
Many APs by default have broadcasting the SSID turned on. Sniffers typically will find
the SSID in the broadcast beacon packets. Turning off the broadcast of SSID in the
beacon message (a common practice) does not prevent getting the SSID, since the
SSID is sent in the clear in the probe message when a client associates to an AP. A
sniffer just has to wait for a valid user to associate with the network to see the SSID.

What are Insertion Attacks?

The insertion attacks are based on placing unauthorized devices on the wireless
network without going through a security process and review.
