The transport protocols on each host computer verify that the application sending the data is authorized to access the network and that both ends are ready to initiate the data transfer.[r]

Medical (ISM) or Unlicensed National Information Infrastructure (UNII) bands. To mitigate the effects of interference from these devices and other sources of electromagnetic interference, RF-based wireless networks employ spread spectrum technologies. Spread spectrum provides a way to “share” bandwi[r]

IEEE 802.11bStill a common standard used today for wireless networks, the IEEE 802.11b standard, defines DSSS networks that use the 2.4 GHz ISM band and communicate at speeds of 1, 2, 5.5, and 11 Mbps. The 802.11b stan-dard defines the operation of only DSSS devices and is backward compat-ible with 80[r]

After discovering the SSID and other information, the attacker can connect to the wireless network to sniff and capture network traffic.. This network traffic can reveal a lot of informa[r]
