Most of us think of home Wi-Fi as the invisible connection that lets a laptop stream a movie, a phone display photos and a printer work from across the room.In practice, it is also the meeting point for many devices, accounts and types of information.
A typical home network may include computers, phones, tablets, smart speakers, televisions, cameras, printers and connected appliances.These devices regularly send and receive data.Some of that traffic is expected, such as opening a bank website or downloading a software update.
Other traffic may be unwanted or suspicious.That is where a firewall comes in.
A firewall is a security system that checks network connections and applies rules about which traffic should be allowed.Think of it as a doorman for digital connections.
It does not know everything about every visitor, but it can help prevent some unexpected traffic from reaching a device.Understanding how firewalls work, where they fit and what they can and cannot protect against can help you make smarter choices about securing your home Wi-Fi.Missed CyberGuy LIVE?
