Subnetting and VLANSs for Security
The place where I stay is a university residence and the network
topology is a Star Topology. It is a Star Topology because everyone who
connects to this network needs to connect to a hub. The hub here is a wireless
hub and is connected to a server in a room.
This network also provides many advantages such as isolation of devices
and centralization advantages such as being able to identify devices and fix
problems. There are also not disruptions when connecting and removing devices
from this network topology.
Below is a picture of the network I would redesign. By
adding more topologies in the network, will make it more complex to work with,
but the advantage is that for a Bus Topology it’s cheaper to setup than that of
a Star. And more hubs and switches can be placed in the network to provide
extra layering of security and well as routing of the network can be managed to
allow certain packets to flow in specific path and filtering of packets.
Each topology here can be placed on a different subnet to ensure that
if one topology gives a problem it can be identified easily. By also adding
subnets it can for example let one subnet have more access to the network than
the other.
