What is the recommended security measure for a wireless network device?

1. Use WEP for encryption

2. Implement WPA2 with EAP authentication

3. Only allow wired connections

4. Use default passwords

The correct answer is: Implement WPA2 with EAP authentication

Implementing WPA2 with EAP authentication is a robust and recommended security measure for a wireless network device. WPA2 (Wi-Fi Protected Access II) provides a strong security framework that is designed to protect wireless networks from unauthorized access. It uses Advanced Encryption Standard (AES) for encryption, which is significantly more secure than older protocols like WEP. Additionally, EAP (Extensible Authentication Protocol) adds a further layer of security by providing a mechanism for the authentication of users on the network. This combination ensures that only authorized users can access the wireless network, mitigating the risks of eavesdropping and unauthorized use. In contrast, other options do not provide the necessary level of security. WEP is outdated and has several vulnerabilities that can be exploited easily, making it an insecure choice for encryption. Allowing only wired connections may provide better security in certain scenarios, but it is not practical for environments that require mobility and flexibility, which are the key advantages of wireless networks. Using default passwords can expose network devices to easy cyber attacks, as many attackers are aware of standard passwords and utilize them. Therefore, adopting WPA2 with EAP is a proven method to ensure secure wireless communication.
