00:00:01,890  -->  00:00:03,150
In this section of the course,
3

3

00:00:03,150  -->  00:00:05,250
we're going to talk about network attacks.
4

4

00:00:05,250  -->  00:00:08,020
Now security is an important part of running our networks,
5

5

00:00:08,020  -->  00:00:09,600
because if we don't secure our networks,
6

6

00:00:09,600  -->  00:00:11,210
someone will eventually find their way in
7

7

00:00:11,210  -->  00:00:13,470
and cause a data breach or other malicious actions
8

8

00:00:13,470  -->  00:00:15,320
against our organizations.
9

9

00:00:15,320  -->  00:00:17,140
Network security is critically important
10

10

00:00:17,140  -->  00:00:18,400
to our modern networks,
11

11

00:00:18,400  -->  00:00:20,960
especially since most of our networks are always on
12

12

00:00:20,960  -->  00:00:22,040
and always connected
13

13

00:00:22,040  -->  00:00:24,940
to the world's largest wide area network, the internet.
14

14

00:00:24,940  -->  00:00:26,140
Now, as you're probably aware,
15

15

00:00:26,140  -->  00:00:28,220
the internet can be a really scary place.
16

16

00:00:28,220  -->  00:00:30,600
There's lots of bad people doing lots of bad things
17

17

00:00:30,600  -->  00:00:32,460
at all hours of the day or night.
18

18

00:00:32,460  -->  00:00:33,940
So in this section,
19

19

00:00:33,940  -->  00:00:35,510
we're going to focus on all the bad things
20

20

00:00:35,510  -->  00:00:36,600
that can happen to your network
21

21

00:00:36,600  -->  00:00:38,410
when you don't secure them properly.
22

22

00:00:38,410  -->  00:00:39,810
Now, in this section of the course,
23

23

00:00:39,810  -->  00:00:42,960
we're going to talk again about domain four, network security,
24

24

00:00:42,960  -->  00:00:46,550
and we're going to cover just one objective, objective 4.2.
25

25

00:00:46,550  -->  00:00:49,330
Objective 4.2 states that you must comparing and contrast
26

26

00:00:49,330  -->  00:00:50,920
common types of attacks.
27

27

00:00:50,920  -->  00:00:53,880
So let's get started learning all about network attacks
28

28

00:00:53,880  -->  00:00:55,363
and threats to our networks.
