Eccouncil Exam ECSS Topic 4 Question 96 Discussion

Actual exam question for Eccouncil's ECSS exam

Question #: 96
Topic #: 4

Jessica, a user, wanted to access the Internet from her laptop and therefore sends a connection request to the access point. To identify the wireless client, the access point forwarded that request to a RADIUS server. The RADIUS server transmitted authentication keys to both the access point and Jessica's laptop. This key helps the access point identify a particular wireless client.

Identify the authentication method demonstrated in the above scenario.

AOpen system authentication

BNull authentication

CShared key authentication

DCentralized authentication

Show Suggested Answer

Suggested Answer: D

The scenario described involves the use of a RADIUS (Remote Authentication Dial-In User Service) server.RADIUS is a client-server protocol that provides centralized network authentication12. In this case, the access point (client) forwards the connection request to the RADIUS server, which then sends authentication keys to both the access point and the user's laptop (supplicant).This process helps the access point identify the wireless client12.

RADIUS servers are also known as AAA (Authentication, Authorization, and Accounting) servers because they provide these three services1. The authentication process begins when a user attempts to log into the network.Their device will request access either through the use of credentials or by presenting an X.509 digital certificate1.The RADIUS server then compares the user's information with a list of users stored in a directory or IDP (Identity Provider)1.

Therefore, the authentication method demonstrated in the scenario iscentralized authentication(Option D), where a central server (in this case, the RADIUS server) handles the authentication of users.

Ah, the age-old question of wireless authentication. I bet the answer is as clear as a sunny day. *winks* Centralized authentication, of course!

Null authentication? Really? This is clearly a case of the access point verifying the client's identity using the RADIUS server. Centralized authentication all the way!
