What does a firewall do?

A firewall protects you from unsolicited and unwanted incoming network traffic. It evaluates incoming traffic for malicious threats, such as hackers and malware, to prevent them from infiltrating your computer or network.

Do you need a firewall?

If you use the internet, it’s smart to have a firewall in place. It provides a first line of defence to help protect your computer and the data stored on it from malicious traffic and potential threats.

Can a firewall be hacked?

A cybercriminal can potentially hack any device or system connected to the internet. Firewalls are more susceptible to being hacked if they’re poorly configured, running outdated software, or zero-day vulnerabilities arise.

Do firewalls prevent viruses?

Firewalls don’t protect against viruses on their own. They manage access to your network, whereas antivirus software serves as cyber protection from malicious viruses. However, some software firewall suites, like Norton 360 Deluxe, include virus protection.

Do you need a firewall at home?

Yes, your home needs a firewall. Without a firewall, you leave yourself open to accepting every connection to your home network without a way to detect and reject incoming threats. Intruders could engage in malicious activities like gaining control over your computer or network, deleting your data, or using your personal information to commit identity theft and other online frauds.
