1

00:00:00,960 --> 00:00:01,840

Excellent.



2

00:00:02,250 --> 00:00:08,730

Let us move on to the next lecture in which we are going to talk about the need of cybersecurity, most



3

00:00:08,730 --> 00:00:10,200

of you already know the answer.



4

00:00:10,230 --> 00:00:12,180

So let us have a quick recap.



5

00:00:12,870 --> 00:00:16,960

The availability of the Internet has transformed the world to a greater extent.



6

00:00:17,160 --> 00:00:18,540

Do you agree with this point?



7

00:00:18,840 --> 00:00:25,140

You should, because, yes, in the early 2000s, there was no Internet to that much extent.



8

00:00:25,140 --> 00:00:33,270

But in the last decade, the use of Internet has rapidly increased and it has also transformed the entire



9

00:00:33,270 --> 00:00:35,250

world to a greater extent.



10

00:00:36,000 --> 00:00:42,540

Until the last decade, people or people weren't doing aware that wireless transactions could be even



11

00:00:42,540 --> 00:00:42,990

made.



12

00:00:43,500 --> 00:00:49,590

But nowadays we can just transfer the over the Internet or we can just transfer the money over the Internet.



13

00:00:49,620 --> 00:00:50,290

Pardon me.



14

00:00:50,910 --> 00:00:54,900

So that is why security is very important in order to save your money.



15

00:00:55,110 --> 00:01:02,070

So, yes, the Internet has transformed the world, but so is the risk of increasing cyberattacks.



16

00:01:02,100 --> 00:01:06,350

That is why we need cybersecurity to tackle all these issues.



17

00:01:07,960 --> 00:01:12,400

The next is via the use of Internet, has resulted in an increase in cyber crimes.



18

00:01:12,850 --> 00:01:21,040

Obviously you use Internet banking, you use Internet insecure coding, you use Internet to store your



19

00:01:21,040 --> 00:01:27,580

photos, personal data, you use Internet to avail different infrastructure services, for example,



20

00:01:27,580 --> 00:01:28,090

cloud.



21

00:01:28,690 --> 00:01:34,540

You use Internet to communicate with your employees or your family and friends.



22

00:01:35,080 --> 00:01:37,920

You use Internet to watch Edeniq videos.



23

00:01:38,110 --> 00:01:38,670

All right.



24

00:01:38,980 --> 00:01:42,790

So just see in what everything around us is.



25

00:01:43,130 --> 00:01:45,100

You know, you're bound to the Internet.



26

00:01:45,820 --> 00:01:52,930

And that is why with the increased use of Internet information that is being exchanged over the Internet



27

00:01:52,930 --> 00:01:54,580

is also increasing.



28

00:01:54,580 --> 00:02:02,800

And that is why the need to preserve the need to save, not protect this information is really important.



29

00:02:02,800 --> 00:02:10,900

And that is why we need security experts and security measures in place to protect your data from getting



30

00:02:10,900 --> 00:02:12,310

into the hands of attackers.



31

00:02:14,570 --> 00:02:19,580

Society has become more dependent on technology in the covid-19 pandemic.



32

00:02:19,970 --> 00:02:25,670

Obviously, you are locked in a room, you are not allowed to go out and you are not allowed to hug



33

00:02:25,820 --> 00:02:26,530

your friend.



34

00:02:26,540 --> 00:02:28,550

You are not allowed to meet different people.



35

00:02:28,550 --> 00:02:30,850

You're not allowed to even shake hands.



36

00:02:31,100 --> 00:02:32,180

So what are you going to do?



37

00:02:32,210 --> 00:02:37,700

You're obviously going to take out your smartphones, start watching, start binge watching Netflix.



38

00:02:37,940 --> 00:02:40,580

Are you going to start learning different things?



39

00:02:40,580 --> 00:02:45,950

You're going to start having a video call with your friends so people have become more dependent on



40

00:02:45,950 --> 00:02:46,610

technology.



41

00:02:46,820 --> 00:02:47,810

And one more thing.



42

00:02:48,320 --> 00:02:50,780

Professionals like us have to work from home.



43

00:02:51,230 --> 00:02:55,640

So, you know, we all have become more dependent on technology.



44

00:02:55,820 --> 00:02:59,090

And that is why the need for security is also increasing.



45

00:02:59,540 --> 00:03:08,210

Oh, people in the covid-19 pandemic, there is a sudden rise in the use of Internet and so is I read



46

00:03:08,960 --> 00:03:17,040

in the newspaper that the number of Gmail accounts created in the pandemic period has almost skyrocketed.



47

00:03:17,360 --> 00:03:19,580

Many people became active on the Internet.



48

00:03:19,580 --> 00:03:28,010

Even senior citizens started using Internet to watch, you know, their kind of things like TV serials



49

00:03:28,010 --> 00:03:31,270

or daily soaps or their local shows.



50

00:03:31,280 --> 00:03:40,190

So that is why society started using the Internet and therefore the security professionals had a tremendous



51

00:03:40,190 --> 00:03:46,130

responsibility on their shoulders to prevent the data that is being exchanged on the Internet.



52

00:03:47,740 --> 00:03:54,310

Now, there is a company called Risk Based Security, it revealed that seven point nine billion records



53

00:03:54,310 --> 00:03:59,890

have been exposed by data breaches in the first nine months of 2019 alone.



54

00:04:00,250 --> 00:04:02,680

Now we're talking about 2019.



55

00:04:02,680 --> 00:04:06,090

I had explained a graph of 2018 17.



56

00:04:06,340 --> 00:04:12,770

And if you remember, the major difference between 17 and 18 was tremendous.



57

00:04:13,510 --> 00:04:16,380

And right now we are in the 20 21.



58

00:04:16,390 --> 00:04:24,190

So although if you go and search on the Internet about the data for 2020, the data is you will see



59

00:04:24,190 --> 00:04:28,590

that there were numerous cyber crimes happen in the year 2020.



60

00:04:28,840 --> 00:04:35,740

So that is why in order to mitigate those attacks and prevent such attacks from happening in the future,



61

00:04:35,950 --> 00:04:38,290

you need security in place.



62

00:04:39,760 --> 00:04:42,760

The next point is with the development of technological industry.



63

00:04:43,210 --> 00:04:44,320

Yes, it is.



64

00:04:44,320 --> 00:04:46,960

There is a need to prevent the confidential data.



65

00:04:47,230 --> 00:04:49,930

As I said, you are locked in a room.



66

00:04:49,930 --> 00:04:53,530

You're not allowed to go out during lockdown.



67

00:04:53,890 --> 00:04:58,850

Obviously, you can start sharing information through different messaging apps, am I right?



68

00:04:59,470 --> 00:05:00,040

Yes.



69

00:05:00,340 --> 00:05:05,670

So in order to prevent that confidential data, you have to have security.



70

00:05:06,070 --> 00:05:13,570

Let's see if you are working and you want to you your company has created an account on their system



71

00:05:13,570 --> 00:05:16,570

for you and the company wants to tell you the password.



72

00:05:16,960 --> 00:05:24,730

Obviously, G.M. is secure, but in spite of telling the password or the account credentials in person,



73

00:05:25,690 --> 00:05:28,660

the manager has to send the details through Internet.



74

00:05:29,740 --> 00:05:32,520

Now, I'm not saying G.M. WhatsApp up is not safe.



75

00:05:32,530 --> 00:05:34,180

That is a controversial topic.



76

00:05:34,420 --> 00:05:41,710

But, yeah, you are sharing information through Internet and that is why you need security to protect



77

00:05:41,710 --> 00:05:43,330

that confidential data.



78

00:05:43,840 --> 00:05:44,380

All right.



79

00:05:44,530 --> 00:05:47,700

Not everyone is equipped with the security knowledge.



80

00:05:47,710 --> 00:05:55,150

That is why training and awareness about cybersecurity has also increased in the 20th century.



81

00:05:55,960 --> 00:06:02,710

And the last point is even financial sectors and health care sectors and educational sectors have started



82

00:06:02,710 --> 00:06:03,940

facing cyber crimes.



83

00:06:04,330 --> 00:06:06,790

Take the example of you right now.



84

00:06:06,790 --> 00:06:11,070

You are sitting here listening to my lecture over the Internet and.



85

00:06:11,970 --> 00:06:16,090

You are using Internet to access these lectures, right?



86

00:06:16,110 --> 00:06:21,070

Even the schools have started delivering lectures through online portal.



87

00:06:21,780 --> 00:06:28,740

So in that way, due to increased use of technology and more dependency on Internet, that is a need



88

00:06:28,740 --> 00:06:29,880

for cyber security.



89

00:06:31,770 --> 00:06:37,760

So I hope this lecture gave you the clear idea of why we need cybersecurity in the next lecture.



90

00:06:38,690 --> 00:06:45,200

We are going to talk about the different organizations associated in the field of cybersecurity and



91

00:06:45,200 --> 00:06:46,940

information security in general.



92

00:06:47,270 --> 00:06:47,900

All right.



93

00:06:48,050 --> 00:06:50,380

I will see you in the next lecture.
