00:00:00,330 --> 00:00:00,900
Welcome back.

2
00:00:01,260 --> 00:00:06,540
In this video, we're going to see how we can install a really useful tool for vulnerability analysis,

3
00:00:07,050 --> 00:00:10,420
probably one of the best tools to perform this process automatically.

4
00:00:11,010 --> 00:00:14,460
It is very easy to use and this tool is called Nessus.

5
00:00:15,820 --> 00:00:22,240
To get it running, we must first download and install it, so to do that, open up your Firefox.

6
00:00:25,600 --> 00:00:32,920
And in the search bar, we can type Nessus, if we scroll down to this tangible link that says Download

7
00:00:32,920 --> 00:00:35,680
Nessus vulnerability assessment, we can click on it.

8
00:00:36,460 --> 00:00:40,540
And right here, we're going to see two different versions of Nessus that we can download.

9
00:00:40,810 --> 00:00:45,280
We can get the free version that allows us to scan up to 16 IP addresses.

10
00:00:45,730 --> 00:00:50,440
And by the way, this Nessus essentials will only allow us to scan inside of the network.

11
00:00:50,650 --> 00:00:56,170
You will not be able to scan external IP addresses using this, however, you will get high speed,

12
00:00:56,320 --> 00:01:00,700
in-depth assessment, free training and guidance and support via community.

13
00:01:01,790 --> 00:01:07,250
Once you start performing, feel life penetration tests and you start scanning different companies,

14
00:01:07,250 --> 00:01:13,090
their networks and so on and so on, this Nessa's professional option will be really useful for you.

15
00:01:13,970 --> 00:01:14,970
It tells you right here.

16
00:01:15,080 --> 00:01:16,910
You get unlimited assessments.

17
00:01:16,910 --> 00:01:20,720
You can scan unlimited IP addresses, you can use it anywhere.

18
00:01:20,930 --> 00:01:24,470
You get live results, configuration assessments, bunch of different things.

19
00:01:24,830 --> 00:01:28,190
But it also comes with a really expensive price.

20
00:01:28,940 --> 00:01:33,620
However, this is something that pays off once you perform real life penetration tests.

21
00:01:36,290 --> 00:01:41,060
Right now, we are interested in the free version, so let us click download on the Net Essentials.

22
00:01:42,280 --> 00:01:48,430
So you can choose to register right here or what else we can do is we can type Nessa's download and

23
00:01:48,430 --> 00:01:50,770
download it straight away to our Linux.

24
00:01:51,310 --> 00:01:53,440
We can click right here, download more sustainable.

25
00:01:53,950 --> 00:01:57,340
And right here we are going to see different Nessus versions.

26
00:01:58,640 --> 00:02:05,750
In this case, since I'm running kalinich 64 bit, I'm interested in this, Nessa's DeBaun am the 64.

27
00:02:06,750 --> 00:02:07,680
If I click on it.

28
00:02:09,250 --> 00:02:09,870
I agree.

29
00:02:10,930 --> 00:02:17,230
If you ask me whether I want to open the file, I want to save it and it will download the file inside

30
00:02:17,230 --> 00:02:18,760
of my download directory.

31
00:02:20,030 --> 00:02:24,860
If you finish in just a few seconds, here it is, it is done, so let's click on this button right

32
00:02:24,860 --> 00:02:25,150
here.

33
00:02:25,160 --> 00:02:31,870
It will open our downloads directory and once it opens up, we can lower this page right here and open

34
00:02:31,880 --> 00:02:33,860
terminal inside of the downloads directory.

35
00:02:34,700 --> 00:02:43,760
To install this, we can run pseudo deep CGY, which stands for the package, and then Dashi, which

36
00:02:43,760 --> 00:02:47,660
stands for instant and we can type the name of the Knesset's.

37
00:02:47,780 --> 00:02:52,880
What you can do is you can just type capital N and then Tabit to to complete it.

38
00:02:53,930 --> 00:03:00,590
Then press enter, it will ask me for the password and put it right here and it will complete the installation

39
00:03:00,590 --> 00:03:01,480
process for us.

40
00:03:02,730 --> 00:03:07,800
Here it is, it finished in just a few seconds and it tells us right here that we can start NASA's scanner

41
00:03:07,920 --> 00:03:09,650
by typing this comment.

42
00:03:10,110 --> 00:03:12,060
So let's just keep it right here.

43
00:03:13,440 --> 00:03:16,260
Let's run it based ClipArt.

44
00:03:17,830 --> 00:03:22,270
Oh, we need to run it with user privileges so it's type pseudo and then paste the comment.

45
00:03:23,940 --> 00:03:31,290
And it will tell us starting Nessus now to go to Nessus, you need to copy this link right here.

46
00:03:33,160 --> 00:03:34,010
Kopitar link.

47
00:03:35,240 --> 00:03:41,690
Go to Firefox's, open another page, if we can close these two pages and we can paste and go to that

48
00:03:41,690 --> 00:03:41,990
link.

49
00:03:43,210 --> 00:03:47,290
Let me enlarge this and it will tell us potential security risk ahead.

50
00:03:47,720 --> 00:03:49,030
We don't really care about this.

51
00:03:49,060 --> 00:03:50,460
We know there is no risk right here.

52
00:03:50,470 --> 00:03:55,200
So click on Advanced and go down here, accept the risk and continue.

53
00:03:55,690 --> 00:03:56,350
Click on that.

54
00:03:57,910 --> 00:04:04,690
And this will start compiling plug ins, this will take a few seconds and soon it will ask us which

55
00:04:04,690 --> 00:04:06,400
version of Nessus we want to install.

56
00:04:07,240 --> 00:04:13,900
And we will also need to provide some additional information, such as email address and usernames and

57
00:04:13,900 --> 00:04:14,410
passwords.

58
00:04:15,740 --> 00:04:20,150
Here it is right here, specify NASA's essentials and click on Continue.

59
00:04:21,340 --> 00:04:26,920
Right here, you will need to provide the first name, the last name and the valid email address.

60
00:04:27,310 --> 00:04:31,660
Now, in case you don't use a valid one, you will not be able to use Nessa's because it will send you

61
00:04:31,660 --> 00:04:35,310
the activation code to the email address that you specify right here.

62
00:04:36,220 --> 00:04:39,370
Now, since they already have an account, just skip this.

63
00:04:40,300 --> 00:04:43,160
And I will go and type my activation code right here.

64
00:04:43,210 --> 00:04:49,210
You should get the same window and the same question asked as soon as you specify the email address

65
00:04:49,210 --> 00:04:54,970
and the first and last name, then you go to your email, find the activation code and typewritten right

66
00:04:54,970 --> 00:04:57,700
here once you type your activation code.

67
00:04:57,730 --> 00:05:00,480
We can continue username and password.

68
00:05:01,150 --> 00:05:05,680
I will set right here, Mr. Hacker, which is my username, and I will type in my password.

69
00:05:05,980 --> 00:05:09,700
It will ask you to set up your own username and to set up your own password.

70
00:05:09,700 --> 00:05:12,130
You can use whatever you want after it.

71
00:05:12,280 --> 00:05:13,090
Click on Submit.

72
00:05:14,480 --> 00:05:20,810
It will tell me Saturday's complete and now it will start the true preparation for this process right

73
00:05:20,810 --> 00:05:27,640
here will take some time and by some time, I think it might take even up to 30 or 40 minutes.

74
00:05:28,860 --> 00:05:34,440
So just take a small break until all of this is over and we're going to continue witnesses in the next

75
00:05:34,440 --> 00:05:34,740
video.
