00:05.150 --> 00:06.660 align:middle line:90%
- Let's start off
with the question.

3
00:06.660 --> 00:09.825 align:middle line:90%
If there's a really secure
network, is that an accident?

4
00:09.825 --> 00:10.975 align:middle line:84%
And the answer is no.

5
00:10.975 --> 00:12.850 align:middle line:90%
Never is it an accident
for a secure network.

6
00:12.850 --> 00:14.225 align:middle line:90%
There's a lot of
design that went

7
00:14.225 --> 00:16.410 align:middle line:90%
into it, a lot of
implementations, policies,

8
00:16.410 --> 00:18.990 align:middle line:90%
and procedures that make it
secure, along with a lot of end

9
00:18.990 --> 00:20.153 align:middle line:84%
user training as well.

10
00:20.153 --> 00:22.570 align:middle line:90%
So in this set of videos,
here's what you and I get to do.

11
00:22.570 --> 00:24.570 align:middle line:90%
We're going to take a
look at some of the design

12
00:24.570 --> 00:26.602 align:middle line:90%
concepts regarding
a secure network,

13
00:26.602 --> 00:28.560 align:middle line:90%
and it's going to focus
on a few basic aspects.

14
00:28.560 --> 00:32.189 align:middle line:90%
For one, how do we control
who gets into the network?

14
00:28.560 --> 00:32.189 align:middle line:90%
For one, how do we control
who gets into the network?

15
00:32.189 --> 00:33.617 align:middle line:84%
That's network access control.

16
00:33.617 --> 00:35.200 align:middle line:90%
And then, once they're
on the network,

17
00:35.200 --> 00:36.870 align:middle line:90%
how do we keep them
safe, making sure

18
00:36.870 --> 00:38.430 align:middle line:90%
their machine
doesn't get malware,

19
00:38.430 --> 00:40.335 align:middle line:90%
or their system doesn't
get compromised?

20
00:40.335 --> 00:42.460 align:middle line:90%
And as they're sending
traffic through the network,

21
00:42.460 --> 00:44.580 align:middle line:90%
how do we control where it
goes, and how do we control

22
00:44.580 --> 00:45.750 align:middle line:84%
if it's protected or not?

23
00:45.750 --> 00:47.855 align:middle line:90%
Those are some of the
design concepts and aspects

24
00:47.855 --> 00:49.980 align:middle line:90%
that we're going to focus
on in this set of videos,

25
00:49.980 --> 00:52.680 align:middle line:90%
and so we'll continue this
discussion with network access

26
00:52.680 --> 00:54.810 align:middle line:90%
control and three of
the primary methods

27
00:54.810 --> 00:57.100 align:middle line:90%
for controlling that
in the very next video.

28
00:57.100 --> 00:59.330 align:middle line:84%
See you there in just a moment.
