Strongest Cipher for WPA2-PSK WLAN Configuration

B.

Many routers provide WPA2-PSK (TKIP), WPA2-PSK (AES), and WPA2-PSK (TKIP/AES) as options.

TKIP is actually an older encryption protocol introduced with WPA to replace the very-insecure WEP encryption at the time.

TKIP is actually quite similar to WEP encryption.

TKIP is no longer considered secure, and is now deprecated.

In other words, you shouldn't be using it.

AES is a more secure encryption protocol introduced with WPA2 and it is currently the strongest encryption type for WPA2-PSK/.

The correct answer for the strongest encryption type for WPA2-PSK is B. AES (Advanced Encryption Standard).

WEP (Wired Equivalent Privacy) is an old and insecure encryption protocol that has been deprecated due to significant security flaws. WEP should not be used to secure wireless networks.

RC4 (Rivest Cipher 4) is also an old and insecure encryption algorithm that has significant vulnerabilities. Therefore, RC4 is no longer recommended for use in encryption protocols.

TKIP (Temporal Key Integrity Protocol) is a legacy encryption protocol that was used as a stopgap measure before WPA2 was standardized. TKIP was designed to address the weaknesses of WEP, but it has also been deprecated due to security flaws.

AES (Advanced Encryption Standard) is the current and recommended encryption protocol for WPA2-PSK. AES is a strong encryption algorithm that is resistant to attacks and provides robust security for wireless networks.

In conclusion, the engineer should configure the WLAN to use AES encryption to ensure the strongest encryption type for WPA2-PSK.
