Segmenting network

[Archangel]

Update: I bought a billion 7800dxl. Installed in 5 mins, segmented using vlans. Fab bit of kit for £135.

we have just had to do a roll out of chip n pin devices across our whole estate and we went with 2g/3g type devices.

where there was no coverage we put a dedicated bt line in.

The idea behind all this was that none of the card payment data went through any of our wan/lan/networks and so we got around any PCI compliance things

So, I think, even if you separate the traffic from the rest of your network because it is still using your network pci compliance is still an issue.

I am aware though that the pci compliance challenges are different depending on the size of your business etc so as a small outfit you may find it is quite easy to ensure you are compliant.

There are a few SOHO DSL routers with VLAN support which would let you segregate wired ports. Something like a Draytek Vigor, Cisco small business router (e.g. 107), Billion make a few, so do Netgear.

I'll have a google for those thanks

Which sort of Juniper do you have. I am using an SSG5 to segment my home network. I previously used an 5GT ADSL to run two different segments.

It's a netscreen 5gt

I'll look into the ssg5, thanks

Thanks smatty, but the chip n pin is via a LAN cable, not wireless.

Perhaps a router which can isolate one LAN port from all others would do it, but don't know where to start searching

I have an Asus Dark Night (RT-N66) which can do a guest wifi network on a separate SSID. All hosts on the guest network are isolated from local systems but can still access the internet. So you could get one of those, stick the chip & pin machine on the guest network and everything else on the normal wifi.

Not sure how it goes for PCI compliance as I think the guest wifi is on the same subnet as the rest but it uses Linux ebtables (layer 2 firewalling) to segregate the guest hosts. Not entirely clear what you need for chip & pin machines.

I need to segment my network for security reasons (PCI compliance).

I have an adsl incoming connection.

A chip and pin card machine which uses a LAN port

A couple of desktop pcs with LAN cards

A couple of laptops using wireless

An android tablet using wireless

An iphone and ipad.

I just need to separate the chip n pin machine from everything else.


Any suggestions as to kit to buy? I'm not a numpty, but I'm also not a network specialist.

(FYI I've currently been using a juniper netscreen, but I've hit problems, first the ios devices will not connect through it, and now the latest software update to my chip n pin machine has stopped it working through the juniper. I can't update the juniper firmware as I don't have a contract with them. Replacement juniper kit looks ruinously expensive and very complicated to program)

Thanks
