Re: Spoofed IP address

How about this,
After you got control of 2 computers, Use tool like SMAC - http://www.klcconsulting.net/smac - to just spoof the MAC Address, and also the IP of the server, or the client...

For controls, maybe use managed switches and Network Management software like HP Openview to control each physical port, both MAC Address and IP? Also, add 2-way mutual authentication between 2 systems would add additional security, i.e. kerberos. All this will give you a lot more secure network, but nothing can guarantee 100% security as you might have guessed.

Obviously, do some cost benefit analysis first, or you might go overboard with your solutions.
...

Just my 2 cents

Hi,
In some common MITM the attacker spoofs it original mac address like
in ARP poisioning.But changing ip is not that easy.

Thanks everyone who read and answer my question.

Given a scenario as below:

When someone wants to launch a man-in-the-middle attack on the
communication between the client and server. In order to make it more
transparent(hard to discover) can the attacker pretended to has the same
IP address as the server(when handling the communication with client
end) while pretending to has the same IP address as the client(when
handling the communication with server end). If it is possible, can you
tell me your solutions.

This is not used to generate real attacks, it is just a concern I come
cross when designing a communication system.

Thanks a lot.
