Abstract
A method for discovering an operating system of a remote machine includes monitoring network communications to detect a plurality of data packets that were generated by the remote machine. The contents of each detected data packet are read so as to extract a packet signature of each detected data packet. Each packet signature is compared with at least one signature of a database of signatures in order to determine a similarity between each packet signature and the signature from the database. A confidence level for at least one candidate operating system is calculated based on the determined similarities. A candidate operating system is selected based on the confidence level for that operating system. Relating computer program product and data processing system are also disclosed.
