Over the years, the
data that we have

3
00:04.163 --> 00:05.830 align:middle line:90%
in our systems that
we have are becoming

4
00:05.830 --> 00:09.010 align:middle line:90%
more and more critical to our
businesses and more valuable.

5
00:09.010 --> 00:11.560 align:middle line:90%
That means also more
valuable to attackers.

6
00:11.560 --> 00:13.720 align:middle line:90%
So we're constantly
looking at better ways

7
00:13.720 --> 00:14.860 align:middle line:84%
of improving our security.

8
00:14.860 --> 00:17.770 align:middle line:90%
We've had the option of
doing VLANs for like forever.

9
00:17.770 --> 00:19.450 align:middle line:90%
We have access
control lists that we

10
00:19.450 --> 00:22.660 align:middle line:90%
can put on a router interface to
protect traffic between VLANs.

11
00:22.660 --> 00:25.390 align:middle line:90%
We have the concept
of a private VLAN.

12
00:25.390 --> 00:26.680 align:middle line:84%
But you know what's tricky?

13
00:26.680 --> 00:28.830 align:middle line:90%
It's tricky when you
have a user like Bob that

14
00:28.830 --> 00:31.330 align:middle line:90%
could connect almost anywhere
now, if they're walking around

14
00:28.830 --> 00:31.330 align:middle line:90%
could connect almost anywhere
now, if they're walking around

15
00:31.330 --> 00:34.330 align:middle line:90%
wirelessly, and make sure
that the access that Bob gets,

16
00:34.330 --> 00:35.800 align:middle line:90%
regardless of where
he connects, is

17
00:35.800 --> 00:37.930 align:middle line:84%
enforced across the enterprise.

18
00:37.930 --> 00:38.890 align:middle line:84%
Well, great news.

19
00:38.890 --> 00:41.620 align:middle line:90%
One very strong method
of being able to do that,

20
00:41.620 --> 00:44.820 align:middle line:90%
to enforce policy, regardless
of where somebody connects,

21
00:44.820 --> 00:46.750 align:middle line:90%
is through the
concept of TrustSec,

22
00:46.750 --> 00:49.300 align:middle line:90%
which is what this set
of videos is all about.

23
00:49.300 --> 00:52.330 align:middle line:90%
And we get to start that
journey in the very next video.

24
00:52.330 --> 00:55.830 align:middle line:90%
So I'll see you there
in just a moment.
