You have just set up a new home router for a small business and are configuring the basic security settings. Which of the following actions should you take to enhance the security of the network?
Set a firewall rule
Enable WPA2 encryption
Set a strong password for the router's admin interface
The correct answer is to set a strong password for the router's admin interface. Default passwords are widely known and could be used by malicious actors to gain control of the router. Changing the password to a strong, unique one significantly enhances security. Merely enabling WPA2 encryption or setting a firewall rule does not address the vulnerability posed by the default admin password. Disabling SSID broadcast can add privacy but does not protect against someone accessing the router's admin interface using the default password.
