Outgoing data units, such as packets, from a computer system that contain data characteristic of an operating system executing on the computer system are intercepted before they are transmitted on a network and masked to impersonate a different operating system if the network is untrusted. The masking may be to re-fingerprint the data units by replacing the data characteristic of the actual operating system with data characteristic of the different operating system. Alternatively, the masking may require discarding the data unit and not transmitting it.
