Study on the Technologies of Operating System Scanning
Abstract:
Operating system (OS) scanning makes it possible to focusing further attacks to known weaknesses of that system. The principle of OS scanning is that different OS vendors may make different implementations for the TCP/IP protocol in their OS products. IP, UDP and TCP as well as application layer protocols are can be used for OS scanning. These methods can be used in active ways sending probes to the targets or passive ways only listening without probes. Totally, whether it used in an active or passive way, the essence for OS scanning is analyzing the characteristics of the packets sent by the targets and matching the characteristics with certain operating system. So, in some cases, we need two or more of these methods together to determine the type of the OS for the target.
