So, yes, in this studio, we will discuss about this fight, what actually I have to tell you in the
networking fundamentals.
But however, this I recorded this session so you can actually see the command line interface for the
next phase of the firewall.
So first, let's see what what the firewall is.
So this is a software firewall and this is installed in your operating system by default.
So it will Windows seven can come to the default firewall.
So what the purpose of the firewall is, it will allow or block the connections based on the rules.
So the connections going from the PC to the alternative are called outgoing connections.
So you can see this is outgoing connections.
So the connection is going from your computer to the ring.
And this is called all outgoing connections and the connections coming from Internet to your computer
are called incoming connections.
So it's pretty straightforward, the terminology, so I read in.
Incoming.
So how will this fight war, uh, distinguish between the, uh, the consciences you need to write some
rules so the rules which you write for outgoing connections are called outbound rules.
And the rules, which you write for the incoming connections are called inbound rules.
So let's say an example, your computer, how to access the Internet.
So for that.
So for that, you need to know the number eighty eight so you will know the phone number eighty on this
computer in our current connections, you will set the record open in which the data should be open
and alert for our corrections.
And you can also set the same group for incoming corrections because generally, the Observer said and
our pages did not report, no redirect also for four forty three.
So that really does not matter because most observers uses the portelli.
So you need to set some boundaries and boundaries so that this firewall will allow the connections to
flow from computer to Internet.
So let's assume that Dysport no, it is not there in any of the rules.
So whenever whenever a server or a computer wants to connect to this, our computer on the property,
if there is no inbound route, then it will simply drop the packet.
It will not allow the packet pass through this application.
So there should be incoming are inbound rule for the parade and similar if there are no outbound rules
about a particular policy.
One, two, three, four, then this firewall will not allow it to resolve the port.
One, two, three, four.
So that's sort of what this is.
Now, let's talk about from the point of view so you can also define some seven to thousand and those
spots will only be better if I were a mineral artist and ruining pots would be rocket fire.
All right.
So in general, we will create a massive pyramid, four four four four.
Right.
So you cannot guarantee that this four four four four pot is in the incoming rules are the outgoing
rules.
So in that case, our payload will not execute.
So far that what we are told is we will set change the number of these four four four four to eight
because we expect that this current computer will connect to the Internet via browser.
So that's why we assume that portability will be open and the firewall will just lost the connection
with this prototype.
And it does not check whether it's outgoing or incoming, even though we will, uh, will be creating
a reversal that will be outgoing from this firewall.
So it will become not to not become a problem anymore.
So we put it in the next video to create the payload on the spot.
So I think I hope you have understood this.
Now, let's go ahead and see how these rules look like open a can opener in Williston and you can see
their Windows defender firewall.
As you can see, my father is on for the private networks and public networks.
So this is just opening an awful and technical disadvantage settings.
So now a window will open, know what you're going to use here?
You can configure the rules, you can click on this inbound rules and it will show you the default rules.
The applications have been added.
So whenever you start a computer with, you know, start a new software to ask for access to private
networks, private networks, yosano, so you'll keep you'll say yes.
So whenever your papers, then the firewall will be added to this rules.
So these are the boundaries, so boundaries without any outside or any outside computer connecting to
your computer, and you can create a new rule by using this new rule on this and you're going to see
what type of deal to create, whether you want to control the program as opposed to combat it.
I want to set the rules for the program so I can set the rules whether it should access the Internet
or not, and Dysport Group that can control connections for ARE or people.
And we are going to see this one point and click next.
And what we can do is we need to apply this to reality and we need to switch with it for a number of
puts it want to operate.
That's a 4000 to 5000.
So all on the spot.
What I want to do next.
So I want to allow the connection from the outside computer to my computer or block the connection.
So just forget about this.
This needs authentication so we don't, uh.
She doesn't control any distractions around the block, so whenever I choose this block the connection,
so any computer with the service put 4000 in between 4000 and 5000, then that connection, we will
Blocher click on next and you can see the private or public and click next.
And you can set a name for this in Bonder like this, you can see on your desk batsuit unacceptable.
So I don't want to say this, but we I will say this will in the next year, we will bypass the firewall.
So that's how you create the boundaries.
You need to switch the polls and you need to decide whether to allow that.
The spots are blocked, the spots on the ground, the same way you can create the old boundaries.
So you can click on this new neutral and you can choose the spot and you can choose the number of votes
it's denied any to specific whether to allow block.
So where do you set the block?
Any service from your computer?
You're not going to do with this post.
So that's why these are called the open process.
So we will set some rules in the next few years and then we'll see how to bypass all these rules.
So that's all for this, a failure, basically.
I hope you have understood.
