No, not really (vms sending identifying traffic), the best detection
method is detection of multiple macs from a single IP, or multiple IPs from
a single mac.

Hi Guys,

I thought that maybe the VM generate some kind of flags in the headers of
the protocols to communicate in the network. Basically I can detect the MAC
address and associate them with and IP address, however there are scenarios
that the people can change the MAC address and the method that I use is not
valid. But Thanks a lot for your fast answer,

Best Regards,

Hi Guys,

I am trying to find a way to ban virtual machines and hypervisors in our
network, I made a quicly research and I didn't found anything.

Can somebody tell me if exist a way or a method to detect that, one of my
ideas is when the VM is configured in NAT mode detect that kind of traffic,
but the problem is when the VM is configured in bridge mode.


It's a bit difficult to take care of this task via Snort as it involves
tracking host vs. mac address vs. traffic.  Snort doesn't help inherently
with this.

Sourcefire makes another product that does this (it's not open source) in
our commercial products.
