OK.
So through all the previous lectures we see in all the weaknesses that can be used by hackers in order
to compromise with WPA and WPA to encrypted networks we see in healthcare how they can use these weaknesses
to crack the password and give the actual key to the network.
We also see that attackers are able to authenticate or view this connect and the voice from any network
without the need to know the key to that network.
And in the previous lecture we see in how we can modify the settings of our outers so that we can increase
the encryption of our network and increase the security of our networks so that hackers can't use the
attacks and give the passwords.
Now in order to fly the settings that we were talking about in the previous lecture you need to be able
to access the settings page for your outer now eater out there has a web page where you can modify the
settings right there.
And it's usually at the IP of that outer.
So first of all I'm going to check and get the IP of my computer or my device.
And I'm just going to do if config like zero.
And as you can see this is the IP of my computer.
So I'm going to open my browser.
And I'm going to now begin to 1 9 2 6 8 0 and the IP of my computer was 25.
Usually the IP of there out there is the first IP and the subnets.
So this is the subnets at the moment it's 1 9 2 1 6 8 0.
And I'm just going to add number one because that's the first IP and the subset.
And that will take me to their outer setting speech.
And as you can see it's asking me to enter a username and a password.
Now there is come in with pre specified username and password.
You can check what the default username and password.
And then I highly recommend you change them after that.
So usually it's written in the manual.
So check them out you'll see what's the default username and password and then you can logon.
Now in some cases the attacker might be doing an eddy authentication attack against you so he might
be preventing you from connecting to your network wirelessly.
So what you can do is you can connect to your out are using a cable username either at cable and when
you do that then the attacker can not use the authentication at that to you authenticate your or disconnect
you.
So you'll be able to access your other settings using the wire and then you can modify your security
settings and change the encryption change the password do all the things that I recommended in the previous
lecture.
In order to increase the security so that the attacker will not be able to attack your network and get
the key.
Now the settings of each rotor are different.
They depend on the manufacture and even the model of their outer.
Well usually they see things the way that you change the settings is the same.
And like 90 percent of the cases there are there is always the first IP of the sub net.
So all we have to do is you get Sure IP utzon if Gothic commands like we did here like we did here on
we go in was 9 1 9 2 1 6 8 0 25.
That's the IP of my device.
And then I changed the last 25 to number one to the first IP.
And that is the IP on my right.
Now I'm going to go to the lesser things now as you can see that there is a lot of things that you can
change for your network and all concerned with the wireless things at the moment.
So as you can see my wireless is enable you can change the name of the network you can change the channel.
And the bandwidth and all that.
So I'm going to go to the security.
And as you can see I'm using WPA encryption with WPA or WPA to ensure authentication and the encryption
using a s t key IP.
And if I go on as you can see that the US is disabled as we said now so basically I'm not using web
so they can not use any of the tags though is I spoke about that allow you to crowd them to encryption.
I am using the loophole which is much more secure and I disable WPA.
So they can much use reeva to determine my WPX been and then reverse engineer my password.
The only way that the hacker can access or get my password is by staying in the handshake first and
then use a wordlist to find my path no my password is very random.
If that actually those in use numbers or digits just just letters.
But it's very random So there's a really small chance of someone being able to guess that password.
Now there is another thing I like to show you here is the access control and use of this you can add
policies so you can add a low policy or deny policy and use it that is based on the mac address.
You can specify a MAC address that you want to allow to connect to your network.
You can also specify MAC addresses that you can deny from YOUR NETWORK.
So for example you can just if you if you dont have many people many visitors coming to the house or
if you're in a company with a specified number of computers and you want to onlly to allow a number
of computers to connect through that network then you can just opt in.
Ask the people good my addresses the people they want to allow and are them in an allowed list now now
even if someone has the actual key the rifka you for your network and they dont exist in the white list
or in the allowed list.
They will not be able to access the network.
You can also add in my list which is if you were you want to deny a certain computer or a certain person
that you think are suspicious.
You can just add the MAC address in the list and they will not be able to connect to your network.
So this is about.
As I said this setting space usually looks different.
The names might be called different names as the names for each of these tabs are usually the main thing
is you're.
You should be able to access their outer settings using the subnet IP and the number one which is the
first IPA and if you're being attacked if you can't connect to your network at all then just use a cable
and modify the settings like we discussed in the previous lectures.
