If you are talking about devices on the network,.. isolate by the MAC address - Rouge devices would not matter then as they would not be allowed resources.

Spoofing a MAC is soooo easy.

that may be,.. however will a 'general user' know how to perform this?

We are a fortune 100, we get intentional attacks daily.

I am curious to why a fortune 100 company would want to use OpenSource. Of course there is nothing wrong with OpenSource, but that is generally not behavior from a large corp.

Actually it's the default option generally if we can.

Do you just need a network discovery type setup, or something that can tell you "This device is not a corporate device, kill it!" ?

Found this.. Let's see if it works. Anyone used it before?

AliehVault does NID. Suricata may also be helpful.

Looks interesting, but there is no link to anything but the appliance.

web interface seems to be okay for Lan Marshal, Nmap is installed but doesn't seem to be running (and there for not scanning). Not sure if there is something else I need to do or what.

Are you looking for rogue APs, or devices that are connected to your network that shouldn't be?

Just devices on the network.

Out of curiosity, are we filtering for red devices (rouge) or things that don't belong (rogue)?

BAHAHAHAHAHAHAHA. Fixed it.

For "Just Devices" something like NetDisco is great... You can follow devices around the network. It records what switch and port a MAC address is seen on... and if the device ever shows up on a different network jack, it can record that too.

I also just discovered phpipam (http://phpipam.net/)... It seems to be good at finding devices, but it doesn't track what switch port they're plugged into, etc...

They have a demo available (http://phpipam.net/phpipam-demo/).

I figured that they flagged red when in the interface.

Green field, red devices. You know.

Red/green: Must be confusing to the colorblind...

I apologize for hijacking the thread. Please carry on.

Looks nice. Can either this or phpiam do email alerts? I'm not seeing that in the demos.

It's been so long since I've used NetDisco, I can't remember. Let me go check phpIPAM real quick... * poof *

Okay, I'm back. It looks like phpIPAM can do email stuff. I don't know what all it can do, but it's worth a quick look. Setup is relatively straight forward.

Jason

so with LanMarshal It's filtering down to Apple devices hence why it didn't work for me. I just need to figure out what to edit here.

Changed

# Check if extracted device info matches 'iPhone OS'.
if grep -q 'iphone_os' $tempfile; then
#echo 'Bingo!';
_extract_device

to we shall see if that does it.

Check if extracted device info matches 'iPhone OS'.

 if grep -q '*' $tempfile; then
#echo 'Bingo!';
_extract_device

You could also try changing it to

	#echo 'Bingo!';
	_extract_device
