Difficulty: EasyWireless Security and Authentication

A technician is installing a new wireless access point in a small home office that lacks a centralized RADIUS authentication server. The client requires a wireless security configuration that utilizes Advanced Encryption Standard (AES) for data privacy while authenticating users via a shared passphrase. Which of the following wireless security standards should the technician select?

  1. WPA2-PersonalAnswer
  2. B
    WPA2-Enterprise
  3. C
    WPA-TKIP
  4. D
    WEP

Answer

WPA2-Personal is the correct security standard because it uses AES encryption and authenticates devices via a pre-shared key without requiring a RADIUS server.
WPA2-Personal utilizes AES encryption (CCMP) to secure wireless communications and uses a pre-shared key (PSK) for authentication, meeting the requirement for AES without needing a centralized RADIUS server.

Step-by-Step Solution

1
Analyze environment authentication constraints
No RADIUS server is present, which rules out enterprise 802.1X solutions.
Enterprise wireless modes require centralized authentication services like RADIUS.
2
Evaluate encryption protocol requirement
The requirement specifies AES (Advanced Encryption Standard).
Legacy protocols like WEP (RC4) and WPA-TKIP do not utilize AES.
3
Select the appropriate security protocol
WPA2-Personal fulfills both requirements by combining CCMP/AES encryption with passphrase-based PSK authentication.
It provides strong encryption without relying on external authentication infrastructure.
