A technician is setting up a wireless router and needs to secure the network from unauthorized access. Which of the following is the best way to secure the network?

Port forwarding is a technique used to direct traffic from external ports to specific internal IP addresses and ports. While it is useful for enabling external access to certain services within a network, it does not inherently provide security against unauthorized access. In fact, improper configuration can expose the network to vulnerabilities, making it unsuitable for securing a wireless network.

Disabling the SSID broadcast can obscure the network from casual users, but it does not provide substantial security. Users who know the network name can still connect if they have the correct credentials. This method offers only a minor deterrent to unauthorized access, rather than a robust security measure.

Screening a subnet involves controlling traffic within a network segment, which can enhance internal security. However, it does not specifically address the issue of securing a wireless network from unauthorized access. This approach is more relevant to managing network traffic rather than preventing unauthorized device connections.
