Now, to be honest, there are a number of different types of villain attacks in modern switched networks.
The villain architecture simplifies network maintenance and improves performance, but it also opens
the door to abuse.
So it's important to understand the general methodology behind these attacks and the primary approaches
to mitigate them.
Vlan hopping enables traffic from one vlan to be seen by another.
Vlan.
Sounds kind of fun, huh?
So as we've already seen before, a virtual local area network, virtual LAN or Vlan, is a group of
hosts with a common set of requirements which communicate as if they were attached to the same broadcast
domain regardless of their physical location.
VLANs work by applying tags to network packets and handling these tags in networking systems, creating
the appearance and functionality of network traffic that is physically on a single network but acts
as if it is split between separate networks.
Capiche?
So let's take a moment and remember the reasons of why we are using VLANs.
Security.
Groups that have sensitive data are separated from the rest of the network.
Cost reduction.
Cost savings result from less of a need for expensive network upgrades.
Higher performance.
The number of router hops reduces and the apparent bandwidth for network users increases.
Broadcast storm mitigation.
Every Vlan only receives its own broadcast packets.
Improved IT staff efficiency.
As we were talking about before VLANs, make it easier to manage the network.
It also simplifies the company's management.
