How To Turn on The Firewall in Windows 10

Posted on February 15, 2018 - by Shannon McFarland - in Building Your InfoSec Program

You might be required to enable the Windows Firewall by your job. Or disable it to use alternative software based on your company’s security policies.

In Microsoft Windows 8 and 10, you get a pre-installed firewall utility. However, it could be disabled by default. You should always check that it is enabled since it is an important security feature for protecting your system. Below you can find the steps to follow to enable or disable this feature in these versions of Windows.

Enabling Your Windows Firewall

Caution: You should only have one software firewall enabled at a time. If you have an antivirus or other security program installed with its own firewall feature, make sure that you disabled that first.

  1. Open the Control Panel in Windows.
  2. Click on System and Security.
  3. Click on Windows Firewall.
  4. If your firewall is disabled, you’ll see Windows Firewall marked “Off.” To turn it on, in the left navigation pane, you can click on Turn Windows Firewall on or off.
  5. In the Customize Settings window, select Turn on Windows Firewall and click OK.

Nice work! If you also have an Apple device, here’s the instructions you need to check your firewall settings for a Mac.


What Is A Firewall?

A firewall is a network security system that is designed to prevent unauthorized access to or from a private network.

It is a security best practice to use a firewall, especially for businesses that have confidential customer data to protect. Enabling your firewall is a common security policy and procedure to protect you and your company.

You can implement a firewall in both hardware and software, or a combination of both. Frequently, businesses use network firewalls to prevent unauthorized Internet users from accessing private networks connected to the Internet. Firewalls are especially important for protecting intranets. All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.

Does your company have a policy about using firewalls?
