CS406: Information Security

This section discusses wireless networking, encryption, and the 802.11 wireless network standards. Wireless networking is advantageous, since it removes the cost of installing cables and doesn't require systems to use a wired connection. What does the term half-duplex mean? What are the most common RF bands used in the United States, and why they are used? Why is it important to encrypt wireless networks? You might remember advanced encryption standard (AES) from the unit on encryption. Which encryption standard for 802.11 networks uses AES? Why should wired equivalent privacy (WEP) and Wi-Fi protected access (WPA) no longer be used for encrypting wireless networks?
