Use a firewall on your computer to block unauthorized access to your network

Firewalls essentially serve as a barrier between your device and the internet. Specifically, they monitor incoming and outgoing network traffic, blocking unauthorized connections and potential cyber threats. Most devices come with built-in firewalls, but for additional peace of mind, you can also opt for third-party firewall software. In doing so, configure the firewall to allow only trusted applications to access the internet and block any suspicious or unknown connections.
