Delude Remote Operating System (OS) Scan by Honeyd

Remote Operating System (OS) detection is an important technique in the network system security and becomes more and more popular these days, because it has close connection with the vulnerability just for an open port. This paper detailedly introduces the techniques of active TCP/IP stack fingerprinting in the remote OS scanning, presents how to simulate the fingerprints of OS which will react to OS detection, uses Honeyd(a software of honeypot) to run some virtual OS to delude remote OS scan.
