Hello, my name is Keith
Barker, and welcome to this set

3
00:05.020 --> 00:05.650 align:middle line:84%
of videos.

4
00:05.650 --> 00:07.210 align:middle line:84%
I'm so glad you're here.

5
00:07.210 --> 00:08.800 align:middle line:90%
When we have
networks and we have

6
00:08.800 --> 00:11.005 align:middle line:90%
devices that want to
connect into those networks,

7
00:11.005 --> 00:14.530 align:middle line:90%
do we just want to allow
anything or anybody to connect?

8
00:14.530 --> 00:16.570 align:middle line:90%
In a corporate environment,
the answer is no.

9
00:16.570 --> 00:19.690 align:middle line:90%
We want to know as soon as
possible who that individual is

10
00:19.690 --> 00:22.240 align:middle line:90%
behind that device and
then, based on that--

11
00:22.240 --> 00:24.400 align:middle line:90%
which we refer to as
authentication and finding out

12
00:24.400 --> 00:25.480 align:middle line:84%
who that user is--

13
00:25.480 --> 00:28.373 align:middle line:90%
based on that we want to
authorize them for the access

14
00:28.373 --> 00:29.290 align:middle line:84%
rights that they need.

15
00:29.290 --> 00:31.200 align:middle line:90%
Or if they're not
authenticated, perhaps we

15
00:29.290 --> 00:31.200 align:middle line:90%
Or if they're not
authenticated, perhaps we

16
00:31.200 --> 00:33.700 align:middle line:90%
want to cut them off right there
at the edge of the network.

17
00:33.700 --> 00:36.310 align:middle line:90%
Well, fortunately, we have
the ability to do that with

18
00:36.310 --> 00:40.660 align:middle line:90%
a technique for network
authentication called 802.1x.

19
00:40.660 --> 00:42.160 align:middle line:90%
And in this set of
videos, I'd like

20
00:42.160 --> 00:44.800 align:middle line:90%
to share with you the framework
and several of the options

21
00:44.800 --> 00:48.280 align:middle line:90%
that we have in working with
network access devices that

22
00:48.280 --> 00:50.800 align:middle line:90%
are the front lines of
defense in conjunction

23
00:50.800 --> 00:53.670 align:middle line:90%
with identity servers like
identity services engine.

24
00:53.670 --> 00:56.530 align:middle line:90%
And that way, we can control
access into our networks

25
00:56.530 --> 00:57.790 align:middle line:84%
at the edge of those networks.

26
00:57.790 --> 01:01.240 align:middle line:90%
And we'll continue our journey
in the very next video as we go

26
00:57.790 --> 01:01.240 align:middle line:90%
And we'll continue our journey
in the very next video as we go

27
01:01.240 --> 01:05.530 align:middle line:90%
further into the details
of what exactly is 802.1x.

28
01:05.530 --> 01:08.250 align:middle line:90%
I'll see you there
in just a moment.
