Which of the following is a common method for safeguarding wireless networks?

Implementing WPA3 encryption is a key strategy for securing wireless networks, as it offers enhanced protection against various types of attacks that threaten data integrity and confidentiality. WPA3 (Wi-Fi Protected Access 3) incorporates stronger encryption protocols and improved security mechanisms compared to its predecessors, making it significantly harder for unauthorized users to gain access to the network. One of its notable features is the introduction of a more resilient authentication method that protects against offline dictionary attacks, which were a vulnerability in earlier versions of Wi-Fi security protocols.

In addition to stronger encryption, WPA3 also addresses some specific cybersecurity concerns by providing individualized data encryption and improved security for public networks. These advancements help in safeguarding sensitive information when connected to wireless networks, making it a widely recommended standard for both individual users and organizations looking to bolster their security posture.

The other options don't provide adequate security measures; for instance, using open network protocols would leave the network vulnerable to unauthorized access, while disabling firewall protections could expose the network to various threats. Allowing unrestricted guest access can also compromise the network's security, as it may enable malicious activity or unauthorized access to sensitive resources.
