What is a Firewall?

Unless you have been hiding under a rock for a long time, you will have had some exposure to the Internet and the wonderful world of computers in some way. The world has become increasingly more technological and more connected in its advancement. This also means an increasing threat in cyber security, as everyone has witnessed with the Russian hacking attempts on the Democratic National Committee.

There are lots of ways to ensure you and your gadgets are protected, ranging from the extremely simple to the hard core complex solutions. If you aren’t one to spend a lot of time and money on complex security systems, then at least make sure you cover the basics by installing a firewall.

A firewall is like a tech wall that filters data coming in and going out of your computer or smartphone so that you are protected from viruses of hackers that want to access your data. Make sure you activate the firewall in your Windows installation or download one from an app store.

If you aren’t sure how to install one, get someone to help you out. Don’t skip it as this is a basic requirement for internet security.
