Our company is looking to redo some networking infrastructure. Previous IT administrators created a daisy chain network topology and all information types, from APs to workstations aggregate on a single network. Lately we have seen some performance issues and wish to rewire much of our network into a star topology network. While doing so, we would like to separate our networks. Previous design considerations have included buying new switches and isolating the traffic on a per-type/per-switch basis. Recently however, I have been thinking about using the switches we already have, and setting up the different data types on the respective VLANS.
What do you know about VLANs?
How does their security rate?
Are they a viable solution for data segragation?
Thanks in advance for you help!
