As I mentioned, 2

2

this course is going to be highly practical. 3

3

Therefore, you will need a lab, 4

4

a place where you can practice 5

5

and experiment with the things 6

6

that you're going to learn in the course. 7

7

Not only that, but having a lab is essential 8

8

for hackers or pen testers 9

9

because let's say you discovered a new attack 10

10

or you want to experiment with a new attack 11

11

or you learned something new online 12

12

and you want to test it, 13

13

then the perfect place for you to test this 14

14

and practice hacking is a hacking 15

15

or a testing lab. 16

16

Now, to create a lab, you just need a number 17

17

of computers with different operating systems 18

18

and you'll need a number of networks 19

19

if you're testing network attacks 20

20

and if you're testing website attacks, 21

21

then you will need to install websites 22

22

on these computers. 23

23

Or you can do all of this inside your computer, 24

24

inside one machine and install everything else 25

25

as virtual machines 26

26

and this is what we're going to do. 27

27

So let's say you have your computer right here. 28

28

This is your main computer that you use every day 29

29

to check your emails or even to watch this course. 30

30

This computer might be running Windows, OS X or Linux. 31

31

It doesn't really matter, it can run any operating system. 32

32

You can keep all the programs that you love and like 33

33

and install a virtualization software 34

34

such as VirtualBox. 35

35

A virtualization software allow us to create a number 36

36

of virtual computers inside your main computer 37

37

so we can have three or four 38

38

or five or 10 computers all installed 39

39

inside your main operating system 40

40

inside your main computer. 41

41

The really cool thing about this 42

42

is you will not need a number of computers, 43

43

you can do everything inside a single computer. 44

44

So what we're going to do 45

45

is we're gonna have a hacking machine. 46

46

This is going to be the machine 47

47

that we will use in order to hack 48

48

into other machines. 49

49

We're going to install Kali Linux on it 50

50

and we'll talk about what that is later on. 51

51

And we're going to have two target machines. 52

52

These are machines that we're gonna try to hack into 53

53

and practice hacking against. 54

54

One of them is gonna be running Windows 55

55

and the other one is going 56

56

to be running an operating system called Metasploitable 57

57

and we'll talk about that once we get to it. 58

58

Now, it is very important to understand 59

59

that you will not lose any functionality 60

60

when you install an operating system as a virtual machine. 61

61

You can use that machine exactly 62

62

as if it's a real physical machine. 63

63

So the really cool thing about using virtual machines, 64

64

first of all, you're not gonna lose any functionality, 65

65

second, all the machines are going 66

66

to be isolated, so as we go through the course, 67

67

we're gonna be trying to hack 68

68

into these machines and we might actually break one of them. 69

69

But that's fine. 70

70

It will not affect your host machine. 71

71

You will be able to easily fix this 72

72

and go back to a snapshot of when the machine was working 73

73

without affecting your main computer. 74

74

The other cool thing is that you'll be able 75

75

to have a number of different versions 76

76

of each of these machines 77

77

and you'll be able to change the configuration easily, 78

78

change the network settings 79

79

or switch between different states of these machines 80

80

and so on. 81

81

So by using virtualization, 82

82

you will not lose any functionality 83

83

but you will gain so many cool features. 84

84

And the main thing to keep in mind 85

85

is your host machine, your main computer 86

86

will never be affected. 87

87

It's completely isolated 88

88

and if we break any of these machines, 89

89

nothing will happen to your precious computer 90

90

that you use every day. 91

91

And this way, you can always use your host machine 92

92

for daily use for checking emails, 93

93

watching the videos, doing whatever you do normally 94

94

and then use your virtual machines for hacking 95

95

and practicing the attacks. 96

96

And this is what I actually do. 97

97

So you can see I have my host machine running OS X 98

98

and I never use this for hacking. 99

99

But right here, I have VirtualBox 100

100

and as you can see, I have a number 101

101

of operating systems installed on it 102

102

and I can literally start any of them 103

103

by selecting the one I want and just click on Start. 104

104

Now, don't worry about this. 105

105

I will show you how to install these virtual machines 106

106

as we go through the course 107

107

but what you need to do right now 108

108

is download and install VirtualBox. 109

109

This program. 110

110

So you can download it from this page. 111

111

I'm gonna include its link in the resources 112

112

and like I said, you can install VirtualBox 113

113

on Windows, OS X or Linux, 114

114

so it supports all operating systems. 115

115

Just pick your operating system from here, 116

116

download the relevant installer 117

117

and install it. 118

118

Installing it is very, very simple. 119

119

All you have to do is literally double click the installer, 120

120

click Next, Next, Next, 121

121

and it'll install it for you. 122

122

Once you start it, you'll see a program similar to this 123

123

but you will not have any virtual machines here 124

124

so it will be empty 125

125

and I will show you how to install all 126

126

of these machines as we go through the course. 127

127

One more thing to do, 128

128

as soon as you install VirtualBox 129

129

is to download and install the Extension Pack. 130

130

This will give you better compatibility 131

131

and it'll allow you to use USB devices 132

132

on the virtual machines 133

133

so you'll be able to use a USB mouse, 134

134

USB keyboard and USB wireless adapters. 135

135

Again, downloading and installing the Extension Pack 136

136

is very, very simple. 137

137

There is only one file. 138

138

It's always the same file for all operating systems. 139

139

It's the same for Windows, for Linux for OS X. 140

140

You just have to click on the download link in here. 141

141

Once you download that, I already have it downloaded, 142

142

so I have it right here 143

143

and this file will only work 144

144

if VirtualBox is installed successfully. 145

145

So first of all, install VirtualBox 146

146

from these links right here like I said. 147

147

Once you download it and install it 148

148

and see a window similar to this, 149

149

without these machines right here, 150

150

we'll see how to install these later, 151

151

then download the Extension Pack from here. 152

152

You'll have its file similar to this file 153

153

and only then you can double click this file 154

154

and it'll automatically open in VirtualBox. 155

155

As you can see, it's telling me 156

156

that I want to install the Extension Pack. 157

157

It's giving me the version 158

158

which is the same version as the version 159

159

of the VirtualBox that I downloaded. 160

160

It has to be the same version, 161

161

otherwise it will not work. 162

162

I'm gonna click on Install. 163

163

We're gonna agree to this license. 164

164

I'm gonna put my password. 165

165

And as you can see, it's telling us 166

166

that the Extension Pack is installed successfully. 167

167

So now we can go ahead 168

168

and install virtual machines in VirtualBox.
