1
00:00:00,320 --> 00:00:01,770
In this section of the course,

2
00:00:01,770 --> 00:00:04,019
we're going to cover six exam objectives

3
00:00:04,019 --> 00:00:06,540
that are focused on the concepts of cyber security

4
00:00:06,540 --> 00:00:08,250
and the Linux operating system.

5
00:00:08,250 --> 00:00:10,470
So this is going to be a pretty long section of the course,

6
00:00:10,470 --> 00:00:11,850
I'm warning you now.

7
00:00:11,850 --> 00:00:15,120
We're going to be covering six objectives across two domains.

8
00:00:15,120 --> 00:00:17,550
This includes domain one, system management

9
00:00:17,550 --> 00:00:19,740
and domain two, security.

10
00:00:19,740 --> 00:00:22,290
First we'll cover objective 1.2.

11
00:00:22,290 --> 00:00:24,030
This states that given a scenario,

12
00:00:24,030 --> 00:00:26,400
you must manage files and directories.

13
00:00:26,400 --> 00:00:28,620
Then we're going to move into five objectives

14
00:00:28,620 --> 00:00:31,980
focused on security, starting with objective 2.1

15
00:00:31,980 --> 00:00:33,930
which states that you must summarize the purpose

16
00:00:33,930 --> 00:00:37,560
and use of security best practices in a Linux environment.

17
00:00:37,560 --> 00:00:39,870
Then we'll talk about objective 2.2

18
00:00:39,870 --> 00:00:41,400
which states given a scenario,

19
00:00:41,400 --> 00:00:43,710
you must implement identity management.

20
00:00:43,710 --> 00:00:45,540
We'll talk about objective 2.3

21
00:00:45,540 --> 00:00:47,010
that states given a scenario,

22
00:00:47,010 --> 00:00:49,380
you must implement and configure firewalls.

23
00:00:49,380 --> 00:00:52,650
And objective 2.4, it states that given a scenario,

24
00:00:52,650 --> 00:00:54,000
you must configure and execute

25
00:00:54,000 --> 00:00:56,460
remote connectivity for system management.

26
00:00:56,460 --> 00:01:00,150
And finally, objective 2.5, that states given a scenario,

27
00:01:00,150 --> 00:01:02,940
you must apply the appropriate access controls.

28
00:01:02,940 --> 00:01:04,019
This section of the course

29
00:01:04,019 --> 00:01:06,750
is all about discovering the best security practices

30
00:01:06,750 --> 00:01:07,950
that we need to implement

31
00:01:07,950 --> 00:01:10,440
in order to keep our Linux system secure.

32
00:01:10,440 --> 00:01:12,630
Like always, we're going to continue to alternate

33
00:01:12,630 --> 00:01:15,600
between our theory lessons and our hands on demonstrations

34
00:01:15,600 --> 00:01:17,130
throughout each of these concepts

35
00:01:17,130 --> 00:01:18,930
as we go through this section.

36
00:01:18,930 --> 00:01:20,790
All of this is going to be done in real time

37
00:01:20,790 --> 00:01:23,340
using our CentOS system once again.

38
00:01:23,340 --> 00:01:25,950
So let's get started talking all about security

39
00:01:25,950 --> 00:01:28,950
in the Linux operating system in this section of the course.
