In addition to activating firewall protection, it's a good idea to disable your router's SSID transmission once all your devices are connected.
A firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization's pre-determined security rules. It acts as a barrier between a trusted internal network and an untrusted external network, such as the internet.
Disabling the router's SSID transmission makes your network less visible to others, adding an extra layer of security to prevent unauthorized access.
