- [Voiceover] If you use a laptop and move around a lot, you connect to a lot of networks. Some of those networks are private, like a network at home or work, while some are public, like those in hotels and coffee shops. If you work in a corporate environment, you probably join a domain-based network when you're in your office or while accessing corporate resources remotely. Have you ever wondered what keeps your computer safe in all of these different environments and how that safety is achieved? Most of the time, at least when connected to a private or public network, it's your basic Windows Firewall.
Go ahead and open Windows Firewall on your own PC. One way to do that is to search for Windows Firewall from the taskbar, and select it in the results. Make sure to select Windows Firewall, and not Windows Firewall with Advanced Security. When you open Windows Firewall, you can immediately see which network profile has been applied to the connection you're using. You can also see the status. Here, I'm connected to a private network. My firewall is on and active, and it's green, so I know it's healthy.
If you're in charge of managing your own firewall and see that the firewall is turned off, you should look into why. It may have been turned off because you installed a third-party firewall, but it could be because malware has infiltrated the system. Go ahead and click Turn Windows Firewall on or off in the left pane. Because my firewall is configured properly, I'm not going to make any changes here. However, if your firewall is turned off and you're sure it should be turned on, go ahead and do that. If your system is infiltrated with malware, though, you might try to turn it on, but won't be able to.
If this is the case, you'll need to get rid of the malware first and return here later. A firewall, by design, blocks undesirable and risky connections. For example, remote desktop isn't set up to pass through the firewall. It's disabled because this opens the system to allow remote users in who have required credentials. If you wanna use Remote Desktop, perhaps to access your work computer from home, you'll have to create an exception for it. I'll show you how to allow this connection, and allowing others is a similar process.
Click the back arrow and click Allow a feature through Windows Firewall. Depending on how you're logged in, you might have to click Change settings, but I don't have to do that. Scroll down to the desired connection or feature. I'll scroll down to Remote Desktop. Tick the appropriate boxes. I'll enable Remote Desktop for private and public network profiles. Now click OK to apply.
You can repeat these steps at any time to disable the connection. Finally, if you're feeling exceptionally vulnerable, you can block all incoming connections. Doing so won't cause you to lose access to the internet or cause you to be unable to send or receive email, but Windows will reject all uninvited incoming traffic. To do this, click Turn Windows Firewall on or off one more time and place a tick in the appropriate boxes. Then click OK.
I've covered just about all you need to know about Windows Firewall. If you've made changes here while following along with me, it might be best to restore the defaults before continuing. To do this, simply click Restore defaults in the Windows Firewall window, shown here. Go ahead and spend a few minutes exploring the other options if you have time. Note that you can click Troubleshoot my network, and you can click Advanced settings to see even more options for working with the firewall. You'll learn about these advanced settings in the movie following this one.
Author and professor Joli Ballew shows you how to get connected, which settings to use to access different resources, and how to keep your system secure. She explains the security implications of different settings, so you can make informed decisions that help protect devices when using public networks. She also helps get the most out of the Window 10 sharing center. Lastly, she explains the native firewall rules, how to create your own inbound and outbound rules, and how to troubleshoot and modify your network connection.
