OS Fingerprinting with ICMP
Operating System (OS) fingerprinting is the process of learning what operating system is running on a device. This can be used by the curious network administrator when they see a new device on the network. Most likely, however, OS fingerprinting is done by an unwarranted party on your network. Just as a bank robber may examine the outside of a bank and watch the comings and goings of employees before robbing the bank, a hacker typically may perform a reconnaissance process on your network prior to launching an attack.
