A network technician is installing a guest wireless network at a coffee shop. When a customer purchases an item, the password for the wireless network is printed on the receipt so the customer can log in. Which of the following will the technician MOST likely configure to provide the highest level of security with the least amount of overhead?
For a guest wireless network in a coffee shop where the password is printed on the receipt, WPA-PSK (Wi-Fi Protected Access - Pre-Shared Key) is the most suitable option. WPA-PSK provides strong security through a shared password without requiring the complexity or overhead of managing an authentication server, such as a RADIUS server which WPA-EAP would require. It is also more secure than older methods like WEP and simpler to implement and use compared to WPS-PIN, making it the ideal choice for a scenario involving frequent changes of users like in a coffee shop.
(WPA-EAP) requiring a RADIUS server for authentication. This might be overkill for a coffee shop’s guest network and could introduce more overhead than necessary. WPA-PSK strikes a good balance between security and ease of use
Very complex question to answer needs a lot of research IMO wording least amount of overhead is the key word for determining answer WPA-PSK over WPA-EAP
.. Guest wireless network the question says. And RADIUS server to authenticate who, coffee buyers? 😂😂😂
WPA-PSK (Wi-Fi Protected Access - Pre-Shared Key) Here's why: WPA-PSK provides a reasonable level of security for a guest network without the complexity of more advanced authentication methods. It uses a pre-shared key (password), which is printed on the receipt, making it easy for customers to log in. WPA-PSK is more secure than older encryption methods like WEP (option B), which is now considered weak and easily breakable. WPA-PSK is the best balance between security and ease of use for a guest network in a coffee shop.
Doesn't need an authentication server and the password could be changed frequently.
but got a good explaination here: https://www.howtogeek.com/204697/wi-fi-security-should-you-use-wpa2-aes-wpa2-tkip-or-both/
i don't even look at it.. so long as you have a lot of public wi-fi experience, you know which to choose ---- they all use WPA-PSK
WPA Pre-Shared Key (PSK)— allows WPA to generate keys from a pre-shared passphrase that you configure. The keys are updated periodically based on time or number of packets. Use PSK in smaller places like Coffee shops where you do not have a RADIUS server. WPA Extensible Authentication Protocol (EAP)— allows WPA to synchronize keys with an external authentication server. The keys are updated periodically based on time or number of packets. Use EAP in larger, enterprise-like deployments where you have an existing RADIUS framework.
WPA-EAP (Wi-Fi Protected Access with Extensible Authentication Protocol) would be the best choice to provide the highest level of security with the least amount of overhead. There is some initial setup but it doesn't require the same level of overhead as PSK
I would have to disagree here, I think keeping a RADIUS server to authenticate users would be quite a bit of overhead. Also the question states that a password is printed on the receipt, but nothing about a username which would be required for an EAP connection AFIAK. I think the original answer of C is likely correct here, even if it isn't the security isn't as strong as WPA-EAP.
Agreed. Changing my answer to C. Simple PSK
i mean , it literally tells you they print the password on the receipt at purchase. pre-shared key
