1
00:00:00,06 --> 00:00:03,07
- Nessus is a web application.

2
00:00:03,07 --> 00:00:05,04
Once you install Nessus,

3
00:00:05,04 --> 00:00:08,06
you can use it through your web browser.

4
00:00:08,06 --> 00:00:11,08
Make sure that you're tapping the right URL.

5
00:00:11,08 --> 00:00:16,02
Local host colon eight, eight, three, four.

6
00:00:16,02 --> 00:00:19,08
Ignore the not secure warning.

7
00:00:19,08 --> 00:00:21,06
Let's sign on to an Nessus

8
00:00:21,06 --> 00:00:24,08
by giving the username and the password.

9
00:00:24,08 --> 00:00:30,02
My username is root.

10
00:00:30,02 --> 00:00:33,08
Click on sign in.

11
00:00:33,08 --> 00:00:36,09
I already ran a couple of scans.

12
00:00:36,09 --> 00:00:39,07
The first scan was host discovery

13
00:00:39,07 --> 00:00:48,01
which finds all the devices connected to your network.

14
00:00:48,01 --> 00:00:55,01
It also shows open ports for each host.

15
00:00:55,01 --> 00:00:59,03
In addition to the host discovery scan type,

16
00:00:59,03 --> 00:01:02,04
there are many others you can run.

17
00:01:02,04 --> 00:01:06,06
To do a new scan, click on the plus sign here.

18
00:01:06,06 --> 00:01:09,00
There are three major scan types;

19
00:01:09,00 --> 00:01:15,03
discovery, vulnerabilities,

20
00:01:15,03 --> 00:01:20,06
and compliance.

21
00:01:20,06 --> 00:01:26,04
Let's run a new basic network scan.

22
00:01:26,04 --> 00:01:32,06
The name of this scan is test.

23
00:01:32,06 --> 00:01:35,08
The targets are the host to be scanned.

24
00:01:35,08 --> 00:01:39,09
We can scan our entire sub-net by typing

25
00:01:39,09 --> 00:01:48,01
10.0.0.0/24.

26
00:01:48,01 --> 00:01:55,03
Select launch and click on it.

27
00:01:55,03 --> 00:01:57,09
The scan is running.

28
00:01:57,09 --> 00:02:03,02
While the scan is going on, you can also see the status.

29
00:02:03,02 --> 00:02:07,09
Nessus is already finding many vulnerabilities here.

30
00:02:07,09 --> 00:02:11,06
Nessus prioritizes the vulnerabilities

31
00:02:11,06 --> 00:02:17,02
and allows you to tackle the most serious ones first.

32
00:02:17,02 --> 00:02:20,06
You like what you've seen so far?

33
00:02:20,06 --> 00:02:23,07
Network vulnerability assessment could be

34
00:02:23,07 --> 00:02:27,05
a user-friendly and satisfying experience.

35
00:02:27,05 --> 00:02:30,00
And Nessus is proof of that.
