-: In this section of the course, 2 2
we're going to cover network architecture and segmentation. 3 3
Now, you may remember, 4 4
back in our coverage of instant responses 5 5
that we mentioned this concept of segmentation. 6 6
Now, this time as we go through it, 7 7
we're going to dive much deeper into this architecture 8 8
that we're going to use 9 9
to be able to create this segmentation for our networks. 10 10
Now, throughout this section, 11 11
we're going to be focused on domain one, security operations, 12 12
and domain two, vulnerability management. 13 13
Specifically looking at objectives 1.1, 1.4, and 2.5. 14 14
Objective 1.1 states, 15 15
that you must be able to explain the importance of system 16 16
and network architecture concepts in security operations. 17 17
But our focus here is going to be on the segmentation 18 18
and network architecture portions of this objective. 19 19
Objective 1.4 states that you must be able to compare 20 20
and contrast threat intelligence 21 21
and threat hunting concepts. 22 22
Here we're going to be specifically focused 23 23
on the idea of honeypots and active defenses 24 24
that are being listed underneath this objective. 25 25
And we also have objective 2.5, which states 26 26
that you must be able to explain 27 27
concepts related to vulnerability response, 28 28
handling, and management. 29 29
And our focus under this objective 30 30
is going to be on asset and change management. 31 31
So in this section of the course, we're going to start out 32 32
by discussing the importance of asset and change management. 33 33
Then we're going to be discussing 34 34
the basic architecture of our networks. 35 35
Next, we're going to dive into segmentation, 36 36
jumpboxes, virtualization, virtualized infrastructure, 37 37
and the use of honeypots. 38 38
Then we're going to discuss the concept of zero trust 39 39
which is a security framework that requires all users 40 40
whether inside or outside of your organization's network 41 41
to be authenticated, authorized, and continuously validated 42 42
for their security configuration and posture 43 43
before being granted or keeping access 44 44
to applications and data. 45 45
Now after that, I'm going to perform a demonstration 46 46
to show you how to configure network segmentation 47 47
and security within your own enterprise networks. 48 48
And finally, we're going to take a short quiz to see 49 49
what you learned during this section of the course, 50 50
and help you review those quiz questions 51 51
to make sure you can explain 52 52
why the right answers were right. 53 53
So let's start exploring network architecture 54 54
and segmentation in this section of the course.
