A store in a shopping center uses a wireless network to provide internet access for three tablet computers. The authentication to the wireless router has been configured as 128-bit WEP. Recently the store employees notice that the internet connection is getting slower. The network administrator of the shopping center reviews the logs of the wireless router and notices many non-store devices are associated with the router. Which two actions can the network administrator do to improve the security of the wireless network access? (Choose two.)
- Use the MAC address filtering feature.
- Change WEP to WPA2 protocol.
- Ensure that the shared key is randomly generated.
- Use a 32-character long SSID.
- Change to the 152-bit WEP protocol.
Explanation: The SSID is used to identify the wireless LAN and should not be considered a method for securing the WLAN. WEP encryption is weak and prone to attacks with wireless hacking tools. WEP should not be used and has been replaced by the much more secure WPA2 protocol. MAC address filtering can ensure that only authorized devices can be associated with the wireless router.
