00:00:00,210 --> 00:00:06,810

Great, let us get started with the next section, and in the first lecture, we're going to talk about



2

00:00:06,810 --> 00:00:10,620

the basic definition of cybersecurity.



3

00:00:11,660 --> 00:00:20,870

Cybersecurity is the practice of defending computers, servers, mobile devices, electronic systems,



4

00:00:21,200 --> 00:00:27,230

networks and data from malicious attacks that often hackers are trying to breach.



5

00:00:28,400 --> 00:00:34,490

It's also known as information technology, security or electronic information security.



6

00:00:35,120 --> 00:00:42,740

Again, this term of cybersecurity applies in a variety of contacts from business to mobile computing,



7

00:00:42,740 --> 00:00:49,790

and it can be divided into a few common categories like network security, application, security,



8

00:00:50,000 --> 00:00:59,840

information security, operational security, disaster recovery and business continuity and user education.



9

00:01:01,250 --> 00:01:07,820

Now, as I said, the global threat continues to evolve at a rapid pace with the rising number of data



10

00:01:07,820 --> 00:01:09,260

breaches per year.



11

00:01:10,230 --> 00:01:16,010

Now, medical devices, retailers and even public entities are experienced cyber attacks.



12

00:01:16,010 --> 00:01:18,830

And that is why we need cybersecurity.



13

00:01:19,490 --> 00:01:23,090

On other alternate definition of cybersecurity can be.



14

00:01:23,630 --> 00:01:33,350

It is the application of technologies, processes and controls to protect the systems, networks, programs,



15

00:01:33,620 --> 00:01:36,550

devices and data from cyberattacks.



16

00:01:37,190 --> 00:01:40,760

It's like protecting something from something.



17

00:01:40,760 --> 00:01:48,740

So cybersecurity is protection of computer systems, of hardware from malicious attacks.



18

00:01:49,220 --> 00:01:56,840

Not people often get confused with information security and cybersecurity because they think that both



19

00:01:56,990 --> 00:01:58,940

these terms are exactly the same.



20

00:01:59,370 --> 00:02:04,160

Well, today, I would like to tell you that these items are not at all seem.



21

00:02:05,060 --> 00:02:12,980

Cybersecurity focuses on protecting the computer systems from unauthorized access, whereas information



22

00:02:12,980 --> 00:02:18,760

security is a broader category that looks to protect all the information assets.



23

00:02:18,770 --> 00:02:24,890

It can be digital copies of something that's a video, lectures or documents.



24

00:02:25,190 --> 00:02:27,050

It can be human resources.



25

00:02:27,710 --> 00:02:29,540

It can be monetary assets.



26

00:02:29,960 --> 00:02:32,420

It can be the employee's identity.



27

00:02:32,990 --> 00:02:35,150

It can be physical security.



28

00:02:35,180 --> 00:02:42,110

So everything that is under falls under the category of information security.



29

00:02:42,410 --> 00:02:49,670

So we can see that cybersecurity is a part of information security, but information security is a much



30

00:02:49,820 --> 00:02:50,870

broader category.



31

00:02:51,200 --> 00:02:57,980

So if anyone asks you the difference between a cybersecurity and information security, make sure that



32

00:02:57,980 --> 00:03:00,350

you understand this difference properly.



33

00:03:01,220 --> 00:03:08,330

And due to the rise of information security, cybersecurity is also on the front line.



34

00:03:08,810 --> 00:03:18,050

So to have a quick recap of this lecture, cyber security is basically the application of technologies



35

00:03:18,050 --> 00:03:19,930

to defend the computer systems.



36

00:03:20,300 --> 00:03:21,680

It can be servers.



37

00:03:21,680 --> 00:03:28,550

They can be mobile electronic devices like your own laptop, your company's laptop or your own mobile



38

00:03:28,820 --> 00:03:30,620

from the malicious attacks.



39

00:03:31,430 --> 00:03:35,420

And information security is a much broader category.



40

00:03:36,380 --> 00:03:42,950

So this is the difference and this is the basic definition of cybersecurity, which you can see on the



41

00:03:42,950 --> 00:03:43,370

screen.



42

00:03:45,260 --> 00:03:51,050

Great, I hope you have understood the definition of cybersecurity, if you still have any doubts,



43

00:03:51,440 --> 00:03:56,370

please feel free to ask us in the Q&A portion in the next lecture.



44

00:03:57,020 --> 00:04:03,080

We are going to talk about the different types of cybersecurity in the first one, which is going to



45

00:04:03,080 --> 00:04:05,060

be the network security.
