    What is a Firewall?

    A firewall is a cyber element, which tries to block access to a private online network, to unauthorized users. These tend to examine every message that comes in and out of the web, so they can obstruct the arrival of the ones that don’t commit to the safety procedures. It works the same way as the door of a house, not letting any strangers into the user’s interspace.

    Its function is a primal thing because it sets the foundation for protection against frequent attacks or infections. Some antivirus companies even get to offer additional firewall protection, to boost the device’s defense system and stop malware entrances.

    How does a Firewall work?

    A firewall sets itself in the cohesion point between a PC – or PC network – and the Internet. Its operations consist in controlling information traffic, which also transmits from one network to another through routers. In addition, the firewall decides which information counts with the safety parameters it has set so they can enter. If it doesn’t relate to these parameters, the firewall will block the entrance for the unwanted user or information.

    Types of Network Firewall Protection

    We'll classify Firewall protection network types as such:

    Hardware Firewalls

    This type of firewall is normally installed on the router you use for internet access. Therefore, it works mainly for device or device network protection.

    Software Firewalls

    Also known as the one type of firewall that comes with the PC’s operative system. In addition, it only protects a single device – not the ones that involve in the network. It’s also set to track info traffic to block the one unauthorized part. You can install this type of firewall from Windows.

    Commercial Software Firewalls

    You can find these ones on antivirus systems. Although it works the same way as the other ones, it offers better levels of protection and bigger control possibilities.

    How to set up a Network Firewall Protection properly?

    A firewall´s functionality is one of the most attractive features it has. However, most of its functioning process won’t happen correctly if the system hasn’t been set up correctly. So, how can you set up a Firewall the proper way?

    Firewall Set-Up for Windows

    For Window systems, you’ll have to go to the Panel of Control. Once inside, you need to select the ‘Networks and Internet’ option. A window will appear after that, in which you’ll pick ‘Windows Firewall. Here you can configure your Firewall as you please, authorizing internet connection to those programs selected. This will obviously exclude the ones unselected.

    If you count with a Windows 10 system, it’s assumed that you’ll have a good firewall set. This would probably not make you install third-party applications. However, this doesn’t extent you from taking precautions while navigating on the web, just so you’ll avoid common threats.

    Surely, it’s an inevitable thing to come across virtual threats while on the Internet. Like we said before, there are many dangers as there is information online, meaning we’re not always entirely safe. That’s why we need to count on good equipment sets which can also establish a general sense of security. And in addition, a good sense of security could set the user for better ways to browse online.
