1
00:00:00,330 --> 00:00:01,440
In this section of the course,

2
00:00:01,440 --> 00:00:02,273
we're going to be exploring

3
00:00:02,273 --> 00:00:04,320
the world of vulnerability management.

4
00:00:04,320 --> 00:00:06,270
Now, vulnerability management is a systematic

5
00:00:06,270 --> 00:00:09,210
and ongoing process of identifying, evaluating,

6
00:00:09,210 --> 00:00:11,490
prioritizing, and mitigating vulnerabilities

7
00:00:11,490 --> 00:00:14,520
in computer systems, in networks and software applications

8
00:00:14,520 --> 00:00:17,430
to maintain a secure and resilient cybersecurity posture.

9
00:00:17,430 --> 00:00:19,860
This process includes vulnerability scanning,

10
00:00:19,860 --> 00:00:21,210
assessment, remediation,

11
00:00:21,210 --> 00:00:23,100
and monitoring to minimize the potential

12
00:00:23,100 --> 00:00:24,120
for security breaches

13
00:00:24,120 --> 00:00:26,670
and ensure the effective management of risk.

14
00:00:26,670 --> 00:00:28,290
So in this section of the course,

15
00:00:28,290 --> 00:00:30,450
we're going to be focused solely on Domain Four

16
00:00:30,450 --> 00:00:32,910
with looking at Objective 4.3.

17
00:00:32,910 --> 00:00:34,560
Now, Objective 4.3 states,

18
00:00:34,560 --> 00:00:36,480
that you must be able to explain various activities

19
00:00:36,480 --> 00:00:38,760
associated with vulnerability management.

20
00:00:38,760 --> 00:00:40,170
First, we're going to be determining

21
00:00:40,170 --> 00:00:42,360
how to best identify vulnerabilities.

22
00:00:42,360 --> 00:00:44,970
This process involves recognizing potential weaknesses

23
00:00:44,970 --> 00:00:47,160
in your systems, applications, and networks,

24
00:00:47,160 --> 00:00:48,780
and then identifying vulnerabilities

25
00:00:48,780 --> 00:00:50,190
is going to be the first critical step

26
00:00:50,190 --> 00:00:52,710
in building out a robust security posture.

27
00:00:52,710 --> 00:00:55,560
Next, we're going to be looking at threat intelligence feeds.

28
00:00:55,560 --> 00:00:58,170
Now, threat intelligence feeds provide essential information

29
00:00:58,170 --> 00:01:00,360
on emerging threats and can help our organizations

30
00:01:00,360 --> 00:01:02,190
to stay more proactive in identifying

31
00:01:02,190 --> 00:01:03,570
and mitigating vulnerabilities

32
00:01:03,570 --> 00:01:05,700
that might be exploited by threat actors out there

33
00:01:05,700 --> 00:01:06,900
in the real world.

34
00:01:06,900 --> 00:01:10,140
Then we're going to cover responsible disclosure programs.

35
00:01:10,140 --> 00:01:11,910
Now, these programs play a vital role

36
00:01:11,910 --> 00:01:13,560
in the cybersecurity ecosystem

37
00:01:13,560 --> 00:01:15,420
by providing a framework for ethical hackers

38
00:01:15,420 --> 00:01:16,770
and security researchers

39
00:01:16,770 --> 00:01:18,930
to report vulnerabilities that they discover.

40
00:01:18,930 --> 00:01:20,850
Your understanding of how these programs work

41
00:01:20,850 --> 00:01:22,920
is going to be essential for fostering collaboration

42
00:01:22,920 --> 00:01:25,740
between security researchers and organizations.

43
00:01:25,740 --> 00:01:28,470
After that, we're going to analyze vulnerabilities.

44
00:01:28,470 --> 00:01:30,960
Now, the analysis step involves evaluating the severity

45
00:01:30,960 --> 00:01:33,630
and potential impact of an identified vulnerability

46
00:01:33,630 --> 00:01:36,270
to allow organizations to prioritize the remediation efforts

47
00:01:36,270 --> 00:01:37,620
more effectively.

48
00:01:37,620 --> 00:01:40,260
Next, we're going to conduct vulnerability scans.

49
00:01:40,260 --> 00:01:41,940
Here you're going to learn how organizations

50
00:01:41,940 --> 00:01:44,580
can employ simple scanning tools and methodologies

51
00:01:44,580 --> 00:01:46,680
to systematically search for vulnerabilities

52
00:01:46,680 --> 00:01:48,660
in their systems and networks.

53
00:01:48,660 --> 00:01:50,100
Then we'll be assessing the results

54
00:01:50,100 --> 00:01:51,750
of those vulnerability scans.

55
00:01:51,750 --> 00:01:52,792
Now, vulnerability assessment

56
00:01:52,792 --> 00:01:55,740
involves comprehensively analyzing the data being gathered

57
00:01:55,740 --> 00:01:57,990
from those scans to determine which vulnerabilities

58
00:01:57,990 --> 00:01:59,460
require immediate attention,

59
00:01:59,460 --> 00:02:00,450
and which ones can be addressed

60
00:02:00,450 --> 00:02:02,640
in a more structured manner later on.

61
00:02:02,640 --> 00:02:05,160
After that, we're going to look at responding and remediating

62
00:02:05,160 --> 00:02:06,720
the vulnerabilities that you've discovered

63
00:02:06,720 --> 00:02:07,920
during your scans.

64
00:02:07,920 --> 00:02:09,360
Now, an effective response strategy

65
00:02:09,360 --> 00:02:11,670
is essential for properly addressing vulnerabilities

66
00:02:11,670 --> 00:02:13,290
and reducing the organization's exposure

67
00:02:13,290 --> 00:02:14,850
to potential threats.

68
00:02:14,850 --> 00:02:16,920
Next, we're going to validate the remediation

69
00:02:16,920 --> 00:02:18,210
of our vulnerabilities.

70
00:02:18,210 --> 00:02:19,650
And this validation ensures

71
00:02:19,650 --> 00:02:21,450
that the remediation actions we've taken

72
00:02:21,450 --> 00:02:24,000
have effectively mitigated the identified vulnerabilities

73
00:02:24,000 --> 00:02:26,100
and that our systems are now secure.

74
00:02:26,100 --> 00:02:28,650
And then we'll conduct vulnerability reporting.

75
00:02:28,650 --> 00:02:30,390
Now, communicating vulnerable findings

76
00:02:30,390 --> 00:02:32,490
and remediation progress is going to be critical

77
00:02:32,490 --> 00:02:33,720
for maintaining transparency

78
00:02:33,720 --> 00:02:37,140
and facilitating decision-making across your organization.

79
00:02:37,140 --> 00:02:38,640
Finally, we'll take a short quiz

80
00:02:38,640 --> 00:02:40,680
to see what you learned during this section of the course,

81
00:02:40,680 --> 00:02:42,540
and review each of those quiz questions fully

82
00:02:42,540 --> 00:02:44,940
to ensure you can explain why each answer was right.

83
00:02:44,940 --> 00:02:46,290
So when you're ready,

84
00:02:46,290 --> 00:02:47,610
let's get started with our coverage

85
00:02:47,610 --> 00:02:50,483
of vulnerability management in this section of the course.
