Hello, everybody. And welcome back in this lecture, we're gonna be covering configuring windows firewalls. So let's go ahead and dive right into it.
Firewalls act as theall AJ ical security safeguard that allows or disallows certain types of traffic based on their port numbers to access your workstation or your workstation to access those types of traffic. Those types of resource is,
um when you get into networking, you're gonna be talking about different types support numbers along with I P addresses stuff like that.
Your poor numbers could be like port 22 poor for 43 things like, you know that that was your examples of port numbers. Basically, those go along inside of TCP and UDP a different ports for each one, and depending on what type of
thing you're trying to do with your computer, like you're trying to access https or if you turn access access
you're going to use the port number along with the I P address in order to access, and that those are the types of communications that are being blocked by the Windows firewall.
The best practices for you to always have your firewall sets on and Usually the firewalls default configurations are
sufficient. They're good enough for you to perform duties on your computer and have a relatively safe experience doing so. But sometimes you will need to show your firewall off, at least temporarily, to allow an application to access the traffic it needs in order to run properly.
Ah, you can disable your your firewall temporarily via the control panel.
And if I haver my mouse over here, you'll see that I'm in the control panel system security and Windows firewall, and then you can customize your settings right from there.
When you have your firewall set toe on, you do have the ability to block all incoming connections. All traffic. Ah, that's going into your computer, out the bats, and you can even block the exceptions list. So there's something that you may need to alter if you have an application that needs access
to certain types of traffic,
and you may need to make an exception list for that. But you also want to make sure that you, um, uncheck that block all incoming connections, setting right there.
You can configure different settings for your home and your work in your public so, you know, going back to Windows seven and Windows A. You can set different viral sittings, depending on whatever trust level you have set for the network that you're going to connect your computer too,
and allow certain applications to access to ruin types of traffic or have access to certain type of traffic coming in.
You can create a firewall exception. This is something that is worth noting because you may be tested on it. Maybe not. I know if you're taking the network, plus you definitely will be. But for the A plus, you may or may not come across it.
But regardless of your working in the I t. Work space to work with PCs, this is something Teoh know about. You want to create a firewall exception to allow access for a nap to have inbound and outbound communication outs to the web,
and you can do so through the far wall configuration settings.
You can allow a napper future to get through the firewall you can set up by port number. If you like the traffic to travel through the firewall, you can have predefined exceptions, and you can set custom rules.
All right, that about wraps up this lecture. I will see you guys in the next one
