To best prevent unauthorized access to a wireless network, which security method should be implemented?

Implementing WPA-EAP is an effective strategy for preventing unauthorized access to a wireless network because it utilizes enhanced security features compared to other methods. WPA-EAP (Wi-Fi Protected Access with Extensible Authentication Protocol) involves both strong encryption and robust authentication mechanisms. This means that it not only encrypts the data transmitted over the wireless network to protect against eavesdropping but also ensures that only authorized users can access the network by requiring them to provide valid credentials.

WPA-EAP supports a variety of authentication methods, allowing it to be tailored to different organizational needs. This makes it particularly suitable for environments where security is a top priority, such as corporate networks that handle sensitive data.

Other options provided may not fully address the requirements for securing wireless networks in the same way. For example, while a BPDU guard is useful in switches to prevent loops, it does not protect wireless networks directly. IP filtering can restrict access based on IP addresses, but it does not provide the same level of encrypted authentication and could be bypassed by determined attackers. A WIDS (Wireless Intrusion Detection System) can monitor for unauthorized access but is only a detection mechanism rather than a preventative measure. Thus, WPA-EAP stands out as the most comprehensive solution for securing a
