It can be a pain to try to wrap your head around the various security measures you need to put in place on your computer. It’s especially tough when some of them have names that are hard to understand, like “firewall.” Don’t worry! We’re about to make it easy for you. Here’s what a firewall does and why you need one.
What is a firewall?
A firewall is a piece of software that helps protect your computer from viruses and other malicious software. It also protects it from hackers, or people trying to access your computer using the Internet. A firewall can be set up at home, or you can have one installed on work computers too.
Firewalls can be used in conjunction with antivirus software and antimalware programs to help keep your computer safe online. They are especially important for companies whose business depends on computers being reliable and secure at all times.
Why do I need a firewall?
A firewall is a software program or computer hardware that works with your operating system to protect your computer from viruses, malware and other threats. Firewalls also prevent hackers from stealing your personal information, such as banking details and passwords.
A firewall can be either software or hardware-based but most firewalls available today are software based because they are less expensive than dedicated hardware units which may cost hundreds of dollars per device connected to the network.

How does a firewall work?
A firewall is one of the most basic and important tools you can have to protect your computer. It’s like a barrier between your computer and the internet, monitoring and controlling the flow of information to and from your computer. All traffic that comes into or goes out of your system will be checked by the firewall before it reaches its destination. The idea is that if someone tries to access something on your computer that they shouldn’t, such as sensitive files or personal information (like credit card numbers), then their attempt will be blocked by the firewall. This way, hackers won’t be able to access any sensitive data stored on your machine.
What is the difference between an application-based firewall and a network-based firewall?
There are three types of firewalls: application-based, network-based and hardware.
Application-based Firewall: This type of firewall works by allowing or blocking specific applications from access the Internet. For example, if you wanted to block Facebook from accessing the web but allow your email to access the web, this could be done with an application-based firewall. Application based firewalls are only capable of protecting one computer at a time though so they’re not as secure as network based firewalls.
Should I have both a hardware and software firewall?
If you have a lot of money and are interested in the most secure firewall solution, then a hardware firewall is for you. If you’re not sure what type of firewall to get, read on!
When it comes to software firewalls (which are less expensive), they can be easier to use than hardware firewalls—but also less secure. A software firewall will block any applications that try to access the internet without your permission. Hardware firewalls work in conjunction with software firewalls by blocking incoming traffic before it reaches your computer’s network card or wireless adapter card. The benefit of having both types of firewalls installed is that they complement each other by working together as a team, so one doesn’t have to do all the heavy lifting while leaving out some important pieces when defending against cyber attacks.
Do Macs get viruses?
Yes, Macs can get viruses. But they are less susceptible to malware and other malicious software than Windows PCs. That’s because the Mac operating system has a built-in firewall that helps block unwanted connections from outside the computer.
As such, you may want to take additional steps on your Mac to add another layer of protection beyond its built-in firewall. You should install antivirus software on your computer (either a paid subscription service or free antivirus software) and use common sense when browsing online: avoid visiting websites that look suspicious or have poor reputations; only download apps from reputable sources; don’t visit sites with adult content; and avoid clicking links in emails unless you know exactly what they contain (and even then you should exercise caution).
You should have a firewall on your computer.
Whether you’re a business or a home user, you should have a firewall on your computer. A firewall is the first line of defense against malware, and it’s important for both types of computers.
Firewalls are either hardware or software (or both). Hardware firewalls are installed inside your computer and only provide protection within that device. Software firewalls run as programs on the operating system level and provide protection for any applications that run through them. Both network-based and application-based firewalls can be used together in order to offer full-system protection from malicious attacks.
