A filter driver or other control logic automatically monitors user input events and outbound network packets in a processing system. According to one embodiment, in response to detecting an outbound network packet, the filter driver automatically determines whether the outbound network packet corresponds to a recent user input event. If the outbound network packet does not correspond to at least one recent user input event, the filter driver automatically prevents the processing system from transmitting the outbound network packet. Other embodiments are described and claimed.
