You own a coffee shop and have recently installed a 802.11g wireless hot spot for the benefit of your customers. For legal reasons you want to minimize your network and avoid liability related to the operations of hot spots. What option specifies the best approach to achieve this goal at your public hotspot?
A.
Allow only trusted patrons to use the WLAN
B.
Use a WIPS to deauthenticate the malicious stations
C.
Require clients STAs to have updated firewall and antivirus software
D.
Disable the WLAN during non business hours
E.
Use the captive portal to force users to agree to an acceptable use disclaimer
F.
Configure WPA2-personal security on your access point
G.
Block TCP port 25out bound on the internet router
Explanation:
The benefi t of a captive portal over an open SSID is that most networks with captive portals have an acceptable use policy. When the user connects to the captive portal, the acceptable use policy or a link to it is usually displayed on the captive portal page, along with a statement such as " Logging in as a registered user indicates that you have read andaccepted the Acceptable Use Policy. " This disclaimer, along with the acceptable use policy,may provide the organization with some legal protection if the user did something illegalwhile connected to the network. This disclaimer can also give the organization the right todisconnect the user from the network if they violate the rules of the acceptable use policy.
