100-150 Question 287
Single answerYou are helping a friend secure their home wireless network. They currently have an older router that supports WEP, WPA, and WPA2 security options. Which security setting should you configure on the router for the best protection, and why?
- A
WEP for compatibility with older devices
- B
WPA with TKIP for moderate security
- C
WPA2 with AES for strong encryption
- D
Disable wireless security and use MAC address filtering instead
Show answer and explanation
Correct answer: C
Explanation
The correct answer is WPA2 with AES because it provides the strongest encryption available for most home routers. Older options like WEP and WPA are outdated and vulnerable to attacks. Disabling wireless security altogether, even with MAC address filtering, is inadequate for protecting a wireless network. Configuring WPA2 with AES ensures the network is secure while maintaining compatibility with most modern devices.
- A. Incorrect.
WEP is an outdated security protocol that is easily compromised due to its vulnerabilities. It should not be used, even for compatibility purposes.
- B. Incorrect.
WPA with TKIP is more secure than WEP but still considered weak by modern standards. It is vulnerable to certain attacks and should be avoided if better options are available.
- C. Correct.
WPA2 with AES provides strong encryption and is considered the most secure option available on many home routers. It is the recommended choice for securing modern wireless networks.
- D. Incorrect.
Disabling wireless security and relying on MAC address filtering is not a secure approach. MAC addresses can be spoofed, leaving the network vulnerable to unauthorized access.
