Data visibility comparison

“

(gentle music) - [Instructor] In our previous module, we discussed data visibility, and that was our ability to monitor and track data flowing through our network. And in this lesson, I want to take a look at some specific technologies and compare how those technologies that we see on screen affect our ability to observe this data in transit. Let's get started by taking a look at ACLs or access control lists. We could think of ACLs much like security checkpoints. They allow us to clearly see and decide what traffic is allowed and not allowed to pass a certain point in the network, typically on a router interface. And this limiting of traffic actually enhances our data visibility because we're looking at very specific allowed data rather than everything. So ACLs, that's going to improve our visibility. Next up, let's consider network address translation and port address translation. Similar technologies. It all goes back to the fact that we are out of publicly routable IP version four…
