Etymology
Examples

Set up a server and fill it with tempting files. Make it hard but not impossible to break into. Then sit back and wait for the crackers to show up.

Observe them as they cavort around in the server. Log their conversations with each other. Study them like you'd watch insects under a magnifying glass.

That's the basic concept behind honeypots and honeynets, systems that are set up specifically so that security experts can secretly observe crackers in their natural habitats.

Notes
'This is not a case which classically has been described as a 'honeypot' or integrity trap, where a bait is set up and authorities wait,' Ms. Manella said.
