Segmenting our Network

[Infotech22]

Hello to all Cybersecurity enthusiastic,

I would like to get some best practices, advices for my next project.

On one location we didn't do barely any segmentation since last IT Manager so it's time to make it more secure and better.

Current Situation is like this:

• VLAN 1 "Clients"
  • Here in our Clients VLAN we have regular clients (notebooks, workstations), printers, VoIP devices, meeting devices (cameras, microphones etc)
• VLAN 2 "Servers"
  • Here in Servers VLAN we have domain controllers, file servers, backup servers, repositories etc

What would be a general recommendation?
I would like to segment it a bit more and create separate VLANs for Printers, VoIP, IoT, Backup Network etc.

Our Infrastructure is as follows:
2 x FortiGate 200F in an HA Cluster (Active/Passive)
2 x Core FortiSwitches in an MC-LAG
3 X Access FortiSwitches

I'm new to this forum.
I'm NSE4 certified.

Yes, that would be a smart approach

I have time to plan so baby steps for now :)

One more question for all of you :)
If I have VLANs with different subnets,
Examples:

• Clinets: 10.10.0.1 /23
• Printers: 10.10.255.1/24

Our Forti Infrastructure is MCLAG, does this means that traffic for clients to printers will go first to FortiGate then back to FortiSwitchse since this is Routing between subnets?

Hello,
As far the SW are managed by FGT is the FGT that will manage the traffic and routing part.
If you run a sniffer or PCAP on FGT GUI you will see traffic how it is going on FGT.
