1
00:00:00,270 --> 00:00:01,530
In this section of the course,

2
00:00:01,530 --> 00:00:04,470
we'll be covering the incident response process.

3
00:00:04,470 --> 00:00:06,900
The incident response process is a critical component

4
00:00:06,900 --> 00:00:09,630
of cybersecurity that outlines a systematic approach

5
00:00:09,630 --> 00:00:11,640
that an organization should take to manage

6
00:00:11,640 --> 00:00:14,250
and mitigate security incidents effectively.

7
00:00:14,250 --> 00:00:16,740
These incidents can range from cybersecurity attacks

8
00:00:16,740 --> 00:00:18,660
and data breaches to system vulnerabilities

9
00:00:18,660 --> 00:00:20,250
and unauthorized access.

10
00:00:20,250 --> 00:00:22,260
The primary goal of an incident response

11
00:00:22,260 --> 00:00:24,870
is to minimize the impact of security breaches,

12
00:00:24,870 --> 00:00:27,840
reduce the time it takes to identify and contain threats,

13
00:00:27,840 --> 00:00:31,290
and facilitate a swift recovery to normal operations.

14
00:00:31,290 --> 00:00:33,510
This process typically involves several key steps,

15
00:00:33,510 --> 00:00:36,060
including incident detection and classification,

16
00:00:36,060 --> 00:00:38,370
containment and eradication of the threat,

17
00:00:38,370 --> 00:00:40,890
evidence, preservation, communication and reporting,

18
00:00:40,890 --> 00:00:43,650
and lessons learned for future preventions.

19
00:00:43,650 --> 00:00:45,960
A well-defined incident response plan is essential

20
00:00:45,960 --> 00:00:48,450
for organizations to maintain resilience in the face

21
00:00:48,450 --> 00:00:49,950
of evolving cyber threats

22
00:00:49,950 --> 00:00:53,580
and to safeguard their digital assets and reputation.

23
00:00:53,580 --> 00:00:54,960
So in this section of the course,

24
00:00:54,960 --> 00:00:56,880
we'll be solely focused on domain four,

25
00:00:56,880 --> 00:00:59,640
more specifically, objective 4.8.

26
00:00:59,640 --> 00:01:01,680
Objective 4.8 states that you must be able

27
00:01:01,680 --> 00:01:05,069
to explain appropriate incident response activities.

28
00:01:05,069 --> 00:01:06,900
First, we'll provide an overview

29
00:01:06,900 --> 00:01:08,880
of the incident response process itself,

30
00:01:08,880 --> 00:01:12,420
including preparation, detection analysis, containment,

31
00:01:12,420 --> 00:01:15,600
eradication, recovery, and lessons learned.

32
00:01:15,600 --> 00:01:17,970
Next, we'll take a look at threat hunting.

33
00:01:17,970 --> 00:01:21,240
Now, threat hunting is a proactive cybersecurity approach

34
00:01:21,240 --> 00:01:22,950
involving the continuous search

35
00:01:22,950 --> 00:01:25,560
and identification of hitting or emerging threats

36
00:01:25,560 --> 00:01:28,740
within an organization's network and systems.

37
00:01:28,740 --> 00:01:31,770
Then we'll discuss the concept of a root cause analysis.

38
00:01:31,770 --> 00:01:35,010
Now, a root cause analysis is a systematic process used

39
00:01:35,010 --> 00:01:38,460
to investigate incidents and identify the underlying factors

40
00:01:38,460 --> 00:01:40,800
or events that led to a security breach

41
00:01:40,800 --> 00:01:42,150
or operational issue.

42
00:01:42,150 --> 00:01:43,320
After that, we will look

43
00:01:43,320 --> 00:01:46,080
at incidents response training and testing.

44
00:01:46,080 --> 00:01:47,760
Incident response training and testing

45
00:01:47,760 --> 00:01:49,560
involves preparing personnel and systems

46
00:01:49,560 --> 00:01:51,930
to effectively respond to security incidents

47
00:01:51,930 --> 00:01:53,640
through table talk exercises,

48
00:01:53,640 --> 00:01:57,390
simulations, drills, and lab exercises.

49
00:01:57,390 --> 00:02:00,660
Next, we'll explore some digital forensic procedures.

50
00:02:00,660 --> 00:02:02,940
These digital forensic procedures refer

51
00:02:02,940 --> 00:02:04,260
to the systematic techniques

52
00:02:04,260 --> 00:02:06,960
and methodologies used to gather, analyze,

53
00:02:06,960 --> 00:02:08,759
and preserve digital evidence

54
00:02:08,759 --> 00:02:13,020
for investigations into cyber crimes or security incidents.

55
00:02:13,020 --> 00:02:15,390
Then we'll review data collection procedures

56
00:02:15,390 --> 00:02:18,030
that you can use during an incident response.

57
00:02:18,030 --> 00:02:20,310
Data collection procedures are established methods

58
00:02:20,310 --> 00:02:23,130
for gathering relevant information and evidence

59
00:02:23,130 --> 00:02:25,830
during an incident response for forensic investigation,

60
00:02:25,830 --> 00:02:29,790
as well as covering a concept known as order of volatility.

61
00:02:29,790 --> 00:02:32,280
After that, we'll look at how disk imaging

62
00:02:32,280 --> 00:02:35,250
and analysis is performed during an incident response.

63
00:02:35,250 --> 00:02:36,660
Disk imaging and analysis

64
00:02:36,660 --> 00:02:39,120
involves creating a bit-by-bit copy

65
00:02:39,120 --> 00:02:41,790
or image of a storage device or disk,

66
00:02:41,790 --> 00:02:44,460
and then examining the contents to recover data,

67
00:02:44,460 --> 00:02:47,820
investigate incidents, or identify security issues.

68
00:02:47,820 --> 00:02:50,460
And finally, we'll take a short quiz to see what you learned

69
00:02:50,460 --> 00:02:51,690
during this section of the course,

70
00:02:51,690 --> 00:02:54,390
and review each of those quiz questions to fully ensure

71
00:02:54,390 --> 00:02:57,030
that you can explain why each answer was right.

72
00:02:57,030 --> 00:02:59,430
So, let's prepare for the inevitable by learning

73
00:02:59,430 --> 00:03:00,930
about the incident response process

74
00:03:00,930 --> 00:03:02,687
in this section of the course.
