Not sure what you mean by tunneling. "heurisitc" as a computer "jargon" usually refers to those things computers alone don't do a good job at. A few days ago somebody here asked a question about character set recognition. That's partly a human task. An Oracle-related case: how do you unambiguously identify a specific user's session in v$session? You may ask whether the session is launched from his desktop and he only launched one session so you can identify by osuser column. If he says it's from Citix Metaframe using a generic account such as APPS, you can consider logon_time combined with v$sql where address=<v$session.sql_address>, and so on. This is heuristic.
