Hello. My name is Dustin, and welcome to Windows Security
00:04
Windows Firewall.
00:05
The Windows Defender firewall is often your PCs first line of defense. It comes with the Windows Defender security suite and is enabled by default.
00:14
You may have seen pop ups or when you've installed a new application or connected to a new network asking about the network or the application itself.
00:22
The Windows firewall is relatively basic but extremely effective as well.
00:26
It can filter both inbound and outbound traffic, block harmful traffic and is relatively easy to configure
00:34
again. One of the best things about the Windows firewall is that it's free and it comes with the operating system, so there's really no reason to not be using it.
00:43
The Windows Firewall has three default profiles that contain a pre built set of rules based on the network you're currently on. Whether that's a domain network, Ah, private network or a guest or public network.
00:56
That's why it's always important to select the correct network type. When you connect to a new network, you don't want to go to Starbucks and connect to their WiFi and then click Private network is the fire will rules aren't configured to properly secure you in that setting.
01:11
This is also where you can configure the default values for I P SEC, which will actually get into an R next slide. But let's go ahead and open the window security center
01:19
and you can do that Windows 10 and search for by typing window security
01:25
and pull it up here. So, as you can see, I've got it pulled up here. It looks like we are all get, so that's always a good sign to see these green check marks. But the one we're gonna look at this time is thief, firewall and network protection.
01:38
See, if you click that and you click it on the left as well, you can see that my firewall is turned on for all three networks. I'm currently connected to both a private network and a public network because I've got a wife. I, um, with my VPN on, so that's there. But this is where you can allow specific APS to the firewall
01:56
if you need a certain game or anything like that,
02:00
and you can also go into the advanced settings and see exactly the inbound and outbound rules. And when I click that you get the little user account control pop up, so I'll click. Yes, and you should see it. Move it to the top monitor.
02:14
So here you can see this is the Windows Defender firewall with advanced security. So this is basically everything you can do with the Windows firewall, and I wouldn't recommend messing with this too much if you're not familiar with it. But it is good toe kind of take a look around and just see all the settings that are there.
02:31
So on the right, you can see a couple of things we can import a policy.
02:35
If you have a specific policy that you want to use, you can import that there. If you set it up, how you like it. You can also export that policy.
02:43
If you do make a bunch of changes and things just aren't working anymore, like you should. You can always restore the default policy as well.
02:51
But here you can see just kind of at a glance overview of the domain profile, the private profile and the public profile as well.
03:01
We click right here to the left. That's what this is all of our inbound rules, and you could see where their enabled whether it's on a private network, all networks or public network. So domain networks and this is just all of our inbound rules. And here you can see the action is allow don't override it. This is the program.
03:21
Any addresses
03:22
and then the ports that the protocol is running on
03:25
and you could do the same for the outbound rules. You can see kind of all of the rules we've got here, um, same set up, and this is where you can make all your changes as well.

Fundamental Windows Security Overview

In Fundamental Windows Security Overview, we examine secure computing within a Windows environment with tools such as the baseline security analyzer, Windows Firewall, and Microsoft Defender. We also provides ways in which a user within a Windows environment can ensure a secure network connection via proper configuration of Ipsec, IIS, and RDP.
