Question 41

Enable MAC address filtering to increase Wi-Fi security.

Enabling MAC address filtering is an effective method for enhancing Wi-Fi security. This approach allows only devices with specific MAC addresses to connect to the network, thereby preventing unauthorized access.

A) Enable MAC address filtering

This option is correct as MAC address filtering restricts access to the network by allowing only pre-approved devices based on their unique MAC addresses. This method provides an additional layer of security, making it harder for unauthorized users to gain access to the network.

B) Implement wired equivalent privacy (WEP)

Implementing WEP is an incorrect choice because WEP is an outdated and insecure encryption protocol. It has numerous vulnerabilities that can be easily exploited by attackers, thus failing to provide adequate protection for Wi-Fi networks.

C) Add more access points

While adding more access points can improve network coverage, it does not inherently enhance security. Without appropriate security measures in place, additional access points could also increase the risk of unauthorized access to the network.

D) Trust local hosts by default

This option is not advisable as it assumes that all local hosts are secure, which can lead to significant vulnerabilities. Trusting local hosts by default can result in unauthorized devices being granted access to sensitive information on the network.

Conclusion

Enabling MAC address filtering stands out as the most effective method to bolster Wi-Fi security by managing which devices can connect to the network. In contrast, the other options either fail to provide adequate security measures or introduce additional risks, thereby reinforcing the importance of using MAC address filtering as a primary security strategy.
