Configuring a SOHO Wireless Router for Advanced Hacker Protection

A technician needs to upgrade a SOHO wireless router's firmware.

The technician resets the router to factory settings and installs the new firmware.

The technician enters the DHCP information and sets the SSID.

Which of the following configurations would provide the MOST protection from advance hackers?

A.

Disable the broadcasting of the SSID.B.

Enable WPA2 authentication for all hosts.

C.

Use private addressing for the DHCP scope.

D.

Install unidirectional antennas.

B.

Option B, "Enable WPA2 authentication for all hosts," would provide the most protection from advanced hackers.

Explanation:

A. Disabling the broadcasting of the SSID would not provide much protection as the SSID can still be discovered through various means, including wireless network sniffers. It would just make it slightly more difficult for casual users to discover the network.

B. Enabling WPA2 authentication for all hosts is the most effective way to protect a wireless network. WPA2 is a stronger encryption protocol than WPA or WEP and provides secure authentication for all devices that connect to the network. It uses a pre-shared key (PSK) or a certificate-based authentication method to secure the network traffic.

C. Using private addressing for the DHCP scope would only hide the IP addresses of devices on the network from the public Internet. It would not provide any additional security for the wireless network itself.

D. Installing unidirectional antennas would not provide any security for the wireless network. It would only change the direction of the wireless signal, making it easier to focus on a specific area.

Therefore, Option B, enabling WPA2 authentication for all hosts, is the best choice to provide the most protection from advanced hackers.
