If we were sending a
child off to school

3
00:03.930 --> 00:05.430 align:middle line:90%
we want the child
to be safe, right?

4
00:05.430 --> 00:07.950 align:middle line:90%
Everywhere, we want that
child to be safe at school,

5
00:07.950 --> 00:09.210 align:middle line:84%
on the way to school.

6
00:09.210 --> 00:11.950 align:middle line:90%
And just like that, we
want our IP packets,

7
00:11.950 --> 00:14.700 align:middle line:90%
if we're sending them to a
server and carrying data.

8
00:14.700 --> 00:17.700 align:middle line:90%
We want those packets in transit
to be safe and protected.

9
00:17.700 --> 00:20.140 align:middle line:90%
We want confidentiality,
data integrity.

10
00:20.140 --> 00:22.500 align:middle line:90%
And one way of getting
that over the years

11
00:22.500 --> 00:25.920 align:middle line:90%
has been a suite of
protocols called IPsec.

12
00:25.920 --> 00:27.540 align:middle line:90%
In this video, in
this set of videos,

13
00:27.540 --> 00:30.000 align:middle line:90%
I'd like to chat with you
about behind the scenes.

14
00:30.000 --> 00:31.910 align:middle line:84%
What are some options for IPsec?

15
00:31.910 --> 00:33.150 align:middle line:84%
Hos does it work?

16
00:33.150 --> 00:34.918 align:middle line:90%
What are some topologies
we could define?

17
00:34.918 --> 00:37.210 align:middle line:90%
And that's going to be the
topic of this set of videos.

18
00:37.210 --> 00:38.877 align:middle line:90%
We're getting the
fundamentals of IPsec.

19
00:38.877 --> 00:41.100 align:middle line:90%
And you and I, we get
to continue this journey

20
00:41.100 --> 00:42.428 align:middle line:84%
in the very next video.

21
00:42.428 --> 00:44.470 align:middle line:90%
So I look forward to seeing
you there, my friend,

22
00:44.470 --> 00:46.410 align:middle line:84%
in just a moment.
