What a smart firewall does and why it matters on home Wi-Fi

Summary

A firewall acts as a digital doorman, controlling network traffic to protect devices. Both router and software firewalls offer distinct layers of security. While essential, firewalls are one part of a comprehensive security strategy, requiring user vigilance and other protective measures.

Key Takeaways

1. A firewall is a security system that checks network connections and applies rules about which traffic should be allowed.
2. A firewall cannot make a weak password strong or determine whether someone is being tricked by a convincing text message.
3. A firewall works best as part of a broader security setup that protects your devices, accounts and important files.
