The Internet can be a scary place.  You have probably heard the news about all the data that has been compromised from Facebook user accounts.  Even if you don’t use Facebook or social media of any kind you should still have a firewall.  It is important to know what the firewall can do and what it will not do. It is imperative to change the default password that the firewall has when it comes out of the box.

A firewall protects your network from unwanted Internet traffic from coming inside your personal network.  Firewalls filter the information passed between your computer and the Internet which then either allows safe traffic through or blocks unsafe traffic.  For instance, a firewall will block unauthorized remote access to your computer. It will not block remote control apps used by technology companies or spammers that you give permission to remote control your computer.  Many scammers will have a pop up message that says your computer has been infected and to call a specific number.  Once you call they will ask to remote into your PC and do more damage and possibly steal information.  It is very important that you trust who you give remote access.  Some firewalls even have software built-in to allow them to act as content filters.  Content filters can protect you from specific file extensions, or specific website content or webpages which may be harmful.

It is very important that you change the default password on your router or firewall.  Every model of firewall uses the same default username and password, which is very easy to obtain with a quick web search.  If a scammer can access your firewall they will be able to change the configuration, thus allowing them into your network. Once they have access they could possibly take control of your computer, change settings to point you to malicious websites, or spoofing websites.

Protect your computer and your personal data by adding a firewall to your network today.
