1
00:00:10,470 --> 00:00:13,100
So let's get started.

2
00:00:13,260 --> 00:00:15,210
The history of cybersecurity.

3
00:00:17,840 --> 00:00:25,820
In this lecture, we learn how cybersecurity evolved when was the first cyber threat that occurred and

4
00:00:25,820 --> 00:00:28,580
obviously the evolution of cybersecurity.

5
00:00:30,960 --> 00:00:39,300
1980S was the era of computer worms, the creation of the first computer worm was a milestone in the

6
00:00:39,300 --> 00:00:41,130
history of cybersecurity.

7
00:00:42,000 --> 00:00:49,830
Researchers traced the very first disastrous computer worm to Robert Demorris, who was a graduate student

8
00:00:49,830 --> 00:00:51,280
from Cornell University.

9
00:00:52,470 --> 00:00:58,170
Morris was curious about the Internet's size and created a boom in 1988.

10
00:00:58,380 --> 00:00:58,900
Gurjit.

11
00:00:59,830 --> 00:01:06,250
The worm was designed to infect Unix systems such that it would count the total connections present

12
00:01:06,400 --> 00:01:15,430
of a modest 021 program that would propagate across a set of networks, use a known vulnerability to

13
00:01:15,430 --> 00:01:18,970
infiltrate Unix terminals and then replicate itself.

14
00:01:20,440 --> 00:01:28,270
However, this turned out to be a huge mistake, a programming error because the worm to infect machine

15
00:01:28,270 --> 00:01:28,930
after machine.

16
00:01:30,130 --> 00:01:38,950
As a result, networks clogged, causing the connection systems to crash the worm, replicating aggressively

17
00:01:38,950 --> 00:01:45,250
to a point where the indirect slowed down to a crawl, leaving untold damage in its wake.

18
00:01:46,290 --> 00:01:53,070
This one is the first to have received full media coverage and was among the very first programs to

19
00:01:53,070 --> 00:01:55,860
return to exploit system until Britta's.

20
00:01:57,550 --> 00:02:05,260
The womb's effect lasted beyond the crash, Internet and connected systems, for one modest, became

21
00:02:05,260 --> 00:02:10,600
the first person to be charged successfully under the Computer Fraud and Abuse Act.

22
00:02:11,710 --> 00:02:18,340
He was fined ten thousand dollars and then sentenced to probation of three years and dismissed from

23
00:02:18,340 --> 00:02:23,950
court, although he went on to become an MIT professor.

24
00:02:25,140 --> 00:02:31,410
This act for the led to the development of computer emergency response team, that is so.

25
00:02:33,040 --> 00:02:38,410
The modest one triggered the start of an entirely new field in computer security.

26
00:02:39,040 --> 00:02:46,420
It led to more people researching on how they can create a deadlier and more effective bombs and viruses.

27
00:02:49,800 --> 00:02:53,010
1990S was the era of viruses.

28
00:02:54,520 --> 00:03:01,300
As previously mentioned, the models will pave the way for new types of malicious programs, viruses

29
00:03:01,300 --> 00:03:05,740
were more aggressive programs that came into light in the 1990s.

30
00:03:06,740 --> 00:03:14,780
Why does such as I Love You and Melissa infected tens of millions of computers, causing a worldwide

31
00:03:14,780 --> 00:03:22,700
failure of immune systems, most of the virus attacks were primarily concerned with financial gains

32
00:03:23,330 --> 00:03:25,030
or strategic objectives.

33
00:03:26,020 --> 00:03:33,130
However, inadequate security solutions at that time caused a huge number of unintended victims to be

34
00:03:33,130 --> 00:03:33,610
affected.

35
00:03:34,820 --> 00:03:42,010
Suddenly, cyber threats and attacks were a huge concern, necessarily being the creations of an immediate

36
00:03:42,010 --> 00:03:42,570
solution.

37
00:03:43,930 --> 00:03:51,160
This problem gave birth to the antivirus software solutions, the programs were designed to detect the

38
00:03:51,160 --> 00:03:56,290
presence of viruses and to prevent them from accomplishing that intended tasks.

39
00:03:57,300 --> 00:04:05,310
The primary delivery method for virus was the use of malicious e-mail attachments, and therefore this

40
00:04:05,310 --> 00:04:15,240
gave rise to the antivirus industry in the early 1990s, saw a sharp growth of companies creating and

41
00:04:15,240 --> 00:04:17,010
retaining antivirus products.

42
00:04:17,760 --> 00:04:22,890
The products were scanning computer systems for the presence of viruses or worms.

43
00:04:23,890 --> 00:04:31,810
At the same time, the available and solution scanned business I.T. systems and tested them with signatures

44
00:04:32,050 --> 00:04:33,250
written in a database.

45
00:04:34,480 --> 00:04:37,920
All of these things we are going to study in the later part of this school's.

46
00:04:39,280 --> 00:04:46,390
However, two significant problems had high impact and the effectiveness of these early antivirus solutions.

47
00:04:48,340 --> 00:04:55,480
The issues persist today in some of the current cybersecurity solutions, the problems included, the

48
00:04:55,480 --> 00:05:02,770
intensive use of resources are a large number of false positives and the former cause of most problems

49
00:05:02,770 --> 00:05:10,480
for users since antivirus solutions scanning systems used a lot of available resources such that the

50
00:05:10,510 --> 00:05:13,660
Internet user activities and productivity.

51
00:05:16,040 --> 00:05:22,820
The endpoint protection platforms slowly proved to be a better security solutions for countering an

52
00:05:22,820 --> 00:05:24,710
increasing rate of virus attacks.

53
00:05:26,060 --> 00:05:31,130
Customers realized that it was possible to detect and stop unknown malware.

54
00:05:31,550 --> 00:05:35,600
Since only a signature of the existing malware was required.

55
00:05:37,690 --> 00:05:39,830
Then come the first hacker group.

56
00:05:40,780 --> 00:05:47,650
What is a hacker group, it consists of individuals with exceptional hacking skills, but they use it

57
00:05:47,650 --> 00:05:51,040
for unauthorized access and illegal activities.

58
00:05:52,030 --> 00:05:59,320
Main purpose of such hacker group is the financial gain, and the money behind it will see the types

59
00:05:59,320 --> 00:06:01,170
of hacking groups later in this course.

60
00:06:01,810 --> 00:06:09,930
But your knowledge Anonymous was the first hacker group that came into the light on October one, 2003.

61
00:06:11,110 --> 00:06:18,310
It first made news when it hacked a website belonging to the Church of Scientology to Deros attack.

62
00:06:18,970 --> 00:06:22,210
And this is where hacking organization struck.

63
00:06:24,840 --> 00:06:33,390
So we saw the history of cybersecurity, we saw how the first one started affecting the world and which

64
00:06:33,390 --> 00:06:38,160
led to the development of many cyber security hacking organizations.

65
00:06:40,640 --> 00:06:45,300
In the next lecture, you will see the scope and career of cybersecurity.

66
00:06:45,980 --> 00:06:52,820
The next lecture is very important for you if you really want to create a nice and decent career in

67
00:06:52,820 --> 00:06:53,780
cybersecurity.
