A network administrator has been tasked with securing the WLAN. Which of the following
cryptographic products would be used to provide the MOST secure environment for the WLAN?
A.
WPA2 CCMP
B.
WPA
C.
WPA with MAC filtering
D.
WPA2 TKIP
Explanation:
The answer is WPA2 CCMP
0
0
Process of Elimination:
WPA2 is stronger than WPA.: This eliminates “B-WPA” and “C- WPA with MAC filtering”
So we are left with just two options:
A-WPA2 CCMP
D-WPA2 TKIP
Now, CCMP is much stronger than TKIP.
So the correct answer is: A-WPA2 CCMP
CCMP is the standard encryption protocol for use with the WPA2 standard and is much more secure than the WEP protocol and TKIP protocol of WPA. CCMP provides the following security
* services:
* Data confidentiality; ensures only authorized parties can access the information
* Authentication; provides proof of genuineness of the user
* Access control in conjunction with layer management
Because CCMP is a block cipher mode using a 128-bit key, it is secure against attacks to the 264 steps of operation.
