1
00:00:07,030 --> 00:00:13,900
To complete our set up of our ethical virtual hacking labs, we're going to see how to set up two different

2
00:00:13,900 --> 00:00:14,650
networks.

3
00:00:15,040 --> 00:00:19,450
We usually like to do ethical hacking inside a closed virtual lab.

4
00:00:19,490 --> 00:00:25,780
That means a private host only network where we can only see the other machines in our ethical hacking

5
00:00:25,780 --> 00:00:28,900
lab not see out to the Internet or vice versa.

6
00:00:28,920 --> 00:00:30,510
Now have the Internet see into us.

7
00:00:30,850 --> 00:00:36,850
So we're going to create a host only network in virtual box that will be a private network just for

8
00:00:36,850 --> 00:00:39,030
our machines and our virtual hacking lab.

9
00:00:39,580 --> 00:00:44,650
That means that we're only going to be able to see from one machine to the other and to our host computer

10
00:00:44,650 --> 00:00:48,080
and from the host computer down into our individual machines.

11
00:00:48,310 --> 00:00:56,170
So this host, only the network is going to have an address range of 10 dot dot three dot some number

12
00:00:56,170 --> 00:00:57,450
from four to 100.

13
00:00:58,030 --> 00:01:03,460
You can go anywhere from one to two hundred fifty four here, but we'll use the range from four to 100

14
00:01:03,460 --> 00:01:04,540
for our machines.

15
00:01:05,050 --> 00:01:06,360
It'll do a couple of things for us.

16
00:01:06,370 --> 00:01:13,330
First of all, it will keep us safe from the Internet so no one can sniff around and find out Linux

17
00:01:13,330 --> 00:01:13,810
box.

18
00:01:14,020 --> 00:01:18,490
No one can sniff around and find out Métis floatable box or even our Windows 10 virtual machines or

19
00:01:18,490 --> 00:01:19,600
Android and so on.

20
00:01:20,050 --> 00:01:24,880
But it will also keep our local area network and the Internet safe from us.

21
00:01:25,240 --> 00:01:31,240
The Calli Linux boxes we saw when we set it up has tons of tools installed in it for Forensic's, for

22
00:01:31,240 --> 00:01:33,850
penetration testing, for real hacking.

23
00:01:34,150 --> 00:01:39,550
And we need to be responsible when we're using that Kelly Linux machine, when we're ethically hacking,

24
00:01:39,550 --> 00:01:43,390
we don't hack networks that we don't have permission to access.

25
00:01:43,720 --> 00:01:46,180
So we can do some things at home in our local area network.

26
00:01:46,180 --> 00:01:53,230
But we usually don't even want Cauli sniffing our Blu ray disc machine, our wireless adapter for wireless

27
00:01:53,230 --> 00:01:56,380
Internet, any security cameras in the house, things like that.

28
00:01:56,680 --> 00:02:02,050
So we want to make sure that we protect ourselves from the Internet and protect the Internet and our

29
00:02:02,050 --> 00:02:09,460
local area network from our Caleigh machine especially so that 10 Dorota three will be our private network.

30
00:02:10,000 --> 00:02:17,260
Then sometimes we'll want to connect to the Internet just to surf, surf the web or to get some updates

31
00:02:17,260 --> 00:02:18,490
for a particular machine.

32
00:02:19,150 --> 00:02:23,560
And we'd still like to be able to see from one machine into another when we connect it out to that public

33
00:02:23,560 --> 00:02:23,980
Internet.

34
00:02:24,640 --> 00:02:31,600
In our social engineering hacking example, we're going to see how to copy the Facebook homepage and

35
00:02:31,600 --> 00:02:39,500
we'll see how to use this ten, not nine public network to set up a fishing page that could capture

36
00:02:39,520 --> 00:02:40,510
user's credentials.

37
00:02:40,750 --> 00:02:45,340
That's really useful for testing in a corporate environment to make sure that people are not clicking

38
00:02:45,340 --> 00:02:46,570
through to phishing emails.

39
00:02:46,840 --> 00:02:49,210
And if they are, we usually do some extra training with them.

40
00:02:49,210 --> 00:02:52,120
We'll see that in the social engineering section coming up.

41
00:02:52,570 --> 00:02:58,420
But for our lab set up to be complete, we need both a private network and a public network.

42
00:02:58,810 --> 00:03:04,900
The private network will be the ten point three set of addresses and our public network will be ten

43
00:03:04,900 --> 00:03:05,920
point nine.

44
00:03:05,920 --> 00:03:11,410
When we see ten point three something, we'll know that our computer is in a private hosted only network

45
00:03:11,410 --> 00:03:14,290
protected from everything and everything's protected from us.

46
00:03:14,830 --> 00:03:19,780
When we'll see the ten point nine, we'll know that we are on the public internet.

47
00:03:19,930 --> 00:03:26,350
We can connect and surf to a website, for example, to Facebook or to Google, or we can do our updates

48
00:03:26,350 --> 00:03:31,120
for Windows updates or do a pseudo app to get update for our Linux boxes.

49
00:03:31,900 --> 00:03:35,920
But we will also be exposed to the Internet and the Internet will be exposed to us.

50
00:03:35,920 --> 00:03:39,400
So we will usually live in this private network.

51
00:03:39,670 --> 00:03:44,140
But it's good also to have this public managed network set up so that we can still see from one machine

52
00:03:44,140 --> 00:03:49,690
into the other and we'll be able to connect out to the public Internet to get updates or do actual Web

53
00:03:49,690 --> 00:03:51,790
surfing or reconnaissance work if we need to.

54
00:03:52,300 --> 00:03:57,400
So we'll see how to set up our private hosts only network next and we'll see in the next lesson.
