A friend is interested in installing a wireless LAN in her small business. She has about a dozen employees. She is concerned about security. Write a two-page letter to explain what security threats she is facing and how she can reduce these threats. Remember that you are writing for a friend, not for a teacher. Do not hand in disorganized notes. Double spacing is good.

There should be some discussion of threats. Yes, it is asked for explicitly, but many students ignore it. Drive-by hacking and evil twins are essential things to include under threats. Also, the types of attacks that drive-by attackers and evil twins can engage in (eavesdropping, making attacks on the network while bypassing the corporate firewall, searching for information on the client PC, installing malware, etc.).

There should be a discussion of core security protocols, including what they do, why 802.11i should be used, and whether to use PSK (which may be viable in a small business) or 802.1X mode.

Rogue access points are not likely, but it would not be technically wrong to include them.

There must be a discussion of evil twin access points, including what they are, the fact that they can defeat core security protocols, and the need to use a VPN with a pre-shared secret.
