Which of the following implementation steps would be appropriate for a public wireless hot-spot?

A.
Reduce power level

B.
Disable SSID broadcast

C.
Open system authentication

D.
MAC filter

Explanation:
For a public wireless hot-spot, you want members of the public to be able to access the wireless
network without having to provide them with a password. Therefore, Open System Authentication
is the best solution.
Open System Authentication (OSA) is a process by which a computer can gain access to a
wireless network that uses the Wired Equivalent Privacy (WEP) protocol. With OSA, a computer
equipped with a wireless modem can access any WEP network and receive files that are not
encrypted.
For OSA to work, the service set identifier (SSID) of the computer should match the SSID of the

wireless access point. The SSID is a sequence of characters that uniquely names a wireless local
area network (WLAN). The process occurs in three steps. First, the computer sends a request for
authentication to the access point. Then the access point generates an authentication code,
usually at random, intended for use only during that session. Finally, the computer accepts the
authentication code and becomes part of the network as long as the session continues and the
computer remains within range of the original access point.
If it is necessary to exchange encrypted data between a WEP network access point and a
wireless-equipped computer, a stronger authentication process called Shared Key Authentication
(SKA) is required.
