How a Firewall Will Protect Your Home

You may think that your home Wi-Fi network is secure, but think again! Anytime you connect to the internet, even at your own home, you may become susceptible to an attack. If you don’t know what a firewall is or what it does, you have increased your risk of cyber-attack from skilled criminals.

A firewall provides protection to your computers and other devices from attack through your network. According to CISCO, a company that specializes in computer data routing technology, a firewall is a security device that monitors incoming and outgoing network traffic. Based on a defined set of security rules, the firewall will decide to allow or to block specific traffic.

There are two main types of firewalls, hardware and software. Envision a hardware firewall as a moat around a city. Hardware firewalls can be found in your home internet router and can protect more than one device. Like the moat, this router is your first line of defense. Next, is a software firewall that will need to be installed on each device that you want to defend. Imagine a lock on a door to each home in a moat-protected city.

To be the most secure, it is recommended that you have both hardware and software firewalls. You can never be too safe when it comes to the security of your home and family.
