A technician is setting up a new wireless router for a home office. Which of the following is the most important first step the technician should take to secure the device?
Update the router's firmware
Change the default password
Enable WPA2 encryption
Disable SSID broadcasting
Changing the default administrator password is the most important first step when securing a new wireless router. Default passwords for many models are publicly known and present an immediate risk of unauthorized access. While updating firmware and enabling strong encryption like WPA2 are also critical security measures, they should be done after securing administrative access. If an attacker compromises the default password, they can potentially undo any other security configurations. Disabling SSID broadcasting is a minor security measure and not a first priority.
