Virtual LANs or VLANs are an important network security control that allow us to logically group together related systems, regardless of where they normally exist on the network. Learn how Virtual LANs may be used to segment networks of differing security levels.
- [Narrator] Virtual LANs, or VLANs,…are an important network security control.…VLANs allow us to logically group together…related systems on a network,…regardless of where they normally exist on that network.…When we create diagrams of our desired network layouts,…they typically look something like this,…with different functional groups…having different network locations.…Users in the accounting department…all share a network that is separate…from users in the sales department…and those in the IT department.…
If our building and floor layout…matched this network diagram exactly we'd be all set.…More often than not; however,…we find ourselves in situations…where users from different departments are mingled together,…and those departments are spread across multiple buildings.…That's where virtual LANs come into play.…We can use them to connect people…who are on different parts of the network to each other,…and also to separate them from other users,…who might actually be geographically close to them.…Virtual LANs extend the broadcast domain.…
