Welcome back.

In this video, we're going to see how we can install a really useful tool for vulnerability analysis,

probably one of the best tools to perform this process automatically.

It is very easy to use and this tool is called Nessus.

To get it running, we must first download and install it, so to do that, open up your Firefox.

And in the search bar, we can type Nessus, if we scroll down to this tangible link that says Download

Nessus vulnerability assessment, we can click on it.

And right here, we're going to see two different versions of Nessus that we can download.

We can get the free version that allows us to scan up to 16 IP addresses.

And by the way, this Nessus essentials will only allow us to scan inside of the network.

You will not be able to scan external IP addresses using this, however, you will get high speed,

in-depth assessment, free training and guidance and support via community.

Once you start performing, feel life penetration tests and you start scanning different companies,

their networks and so on and so on, this Nessa's professional option will be really useful for you.

It tells you right here.

You get unlimited assessments.

You can scan unlimited IP addresses, you can use it anywhere.

You get live results, configuration assessments, bunch of different things.

But it also comes with a really expensive price.

However, this is something that pays off once you perform real life penetration tests.

Right now, we are interested in the free version, so let us click download on the Net Essentials.

So you can choose to register right here or what else we can do is we can type Nessa's download and

download it straight away to our Linux.

We can click right here, download more sustainable.

And right here we are going to see different Nessus versions.

In this case, since I'm running kalinich 64 bit, I'm interested in this, Nessa's DeBaun am the 64.

If I click on it.

I agree.

If you ask me whether I want to open the file, I want to save it and it will download the file inside

of my download directory.

If you finish in just a few seconds, here it is, it is done, so let's click on this button right

here.

It will open our downloads directory and once it opens up, we can lower this page right here and open

terminal inside of the downloads directory.

To install this, we can run pseudo deep CGY, which stands for the package, and then Dashi, which

stands for instant and we can type the name of the Knesset's.

What you can do is you can just type capital N and then Tabit to to complete it.

Then press enter, it will ask me for the password and put it right here and it will complete the installation

process for us.

Here it is, it finished in just a few seconds and it tells us right here that we can start NASA's scanner

by typing this comment.

So let's just keep it right here.

Let's run it based ClipArt.

Oh, we need to run it with user privileges so it's type pseudo and then paste the comment.

And it will tell us starting Nessus now to go to Nessus, you need to copy this link right here.

Kopitar link.

Go to Firefox's, open another page, if we can close these two pages and we can paste and go to that

link.

Let me enlarge this and it will tell us potential security risk ahead.

We don't really care about this.

We know there is no risk right here.

So click on Advanced and go down here, accept the risk and continue.

Click on that.

And this will start compiling plug ins, this will take a few seconds and soon it will ask us which

version of Nessus we want to install.

And we will also need to provide some additional information, such as email address and usernames and

passwords.

Here it is right here, specify NASA's essentials and click on Continue.

Right here, you will need to provide the first name, the last name and the valid email address.

Now, in case you don't use a valid one, you will not be able to use Nessa's because it will send you

the activation code to the email address that you specify right here.

Now, since they already have an account, just skip this.

And I will go and type my activation code right here.

You should get the same window and the same question asked as soon as you specify the email address

and the first and last name, then you go to your email, find the activation code and typewritten right

here once you type your activation code.

We can continue username and password.

I will set right here, Mr. Hacker, which is my username, and I will type in my password.

It will ask you to set up your own username and to set up your own password.

You can use whatever you want after it.

Click on Submit.

It will tell me Saturday's complete and now it will start the true preparation for this process right

here will take some time and by some time, I think it might take even up to 30 or 40 minutes.

So just take a small break until all of this is over and we're going to continue witnesses in the next

video.
