What Is Windows Firewall?

Windows Firewall is a network security system that helps protect your computer from unwanted access and intrusion. It does this by blocking incoming and outgoing traffic that doesn’t meet certain security criteria. Windows Firewall is automatically enabled on all Windows PCs, but it’s important to configure it properly to get the most out of its features.

How to Enable and Configure Windows Firewall

The Benefits of Enabling and Configuring Windows Firewall

Windows Firewall is a pre-installed firewall program in Windows that helps protect your computer from malicious attacks and control the traffic that goes in and out of your computer. Enabling and configuring Windows Firewall can offer the following benefits:

  1. Protection against malicious attacks – Windows Firewall can block unauthorized access to your computer, which can help protect it from malware, ransomware and other types of cyberattacks.
  2. Control over traffic – Windows Firewall can help you manage the traffic that goes in and out of your computer, so you can more easily control what applications and websites can access the internet.
  3. Improved performance – Windows Firewall doesn’t use a lot of system resources, so enabling it won’t impact your computer’s performance.

What to Do if Windows Firewall Is Blocking a Program

If Windows Firewall has been enabled and is still blocking a program, it might be because the program is deemed a risk by Windows. However, if you trust the program, there’s an easy fix.

In the Windows Control Panel, search “Windows Defender Firewall” and select “Allow an App Through Windows Firewall”.

You’ll see here a list of all the programs that have been granted access through the firewall. You can manually add a new entry by clicking on “Change Settings” and then “Allow Another Program” or you can select an existing entry and click on “Edit” if you wish to make changes.

Once you have selected or added a program, you’ll be able to specify which type of networks it can access (Home/Work or Public). If in doubt, keep this set to Home/Work for maximum security. Finally, click on the checkbox for each type of network to confirm your changes.

How to Check if Your PC Is Protected by Windows Firewall

This can be done by launching the Windows Security Center, which you can find in your Control Panel. Click on “Windows Defender Firewall” and then click “Advanced settings“.

You can also verify that all inbound traffic is being blocked unless it is explicitly allowed.
