When it comes to protecting yourself online, there’s a lot of confusion. Between VPNs, two-factor authentication, antivirus software and firewalls, there are so many ways to protect yourself that it can be hard to track them all.
One big mistake people make is buying one service and wiping their hands clean. They’ll think, “Well, I got this highly-rated program, so I’m completely safe!” Sadly, that’s not enough.
If you want to truly protect your gadgets, you’ll need to understand the programs you use. Firewalls and antivirus programs are incredibly helpful, but they often get confused with one another. People might use one and think they don’t need the other, weakening overall security. Thanks to our sponsor, TotalAV, we created a guide on these two safety tools: what they are, how they’re different, and how they can help you.
What is a firewall?
If you’re not entirely sure what a firewall is, think of it as a modern version of a medieval gatekeeper. Hundreds of years ago, guardsmen in armor used to stand by their city’s front gate, keeping a close eye on all the merchants who brought their goods in for trade. Your firewall is a digital guardsman watching the data streaming in and out of your system.
Just as an armored guard would halt suspicious visitors, so, too, does your firewall block suspicious data from entering your system. A firewall is a protective barrier separating your devices from the dangers of the internet.
