- [Tutor] So, as I mentioned
to you before in an SDN solution,
the control plane is separated from the data plane
and implemented in a software application.
It also allows you to do a lot of different integrations,
and at the end of the day automate a lot of your tasks
to provide better consistency.
And of course, at the end of the day to minimize the effort
of maintaining troubleshooting and operating a network.
Now, also there are several security benefits
to that because if you're consistent,
of course it is expected
that security best practices will be implemented
in a more consistent manner.
And as you also already learnt about the Cisco SDN Solutions
like Cisco ACI and Cisco DNA Center,
they provide a lot of capabilities
to do either micro segmentation,
or very robust segmentation policies
and also to maintain visibility
into what is actually happening in the network,
especially in DNA Center you have things
that can be integrated like the Cisco ISE Solution,
so the identity service engine for you
to perform a lot of robust policy enforcement
and visibility integrating with other technologies
like the Cisco's StealthWatch as well.
So these technologies not only allow you to scale
and be consistent, but also provide a lot
of security capabilities as well.
We already mentioned the Cisco ETA Solution
for detecting threats in encrypted traffic,
and gaining visibility of what's actually happening
in the network with integration with Cisco's StealthWatch
and at the end of the day providing consistent
and very robust policies
to the underlying networking devices.
