Which is a computer system on the Internet that is expressly set up to attract and trap people who attempt to penetrate other people's computer systems?

A honeynet is a network composed of multiple honeypots, not a single computer system set up to trap attackers.

A honeypot is a security resource specifically configured to be probed, attacked, or compromised, serving as a trap for malicious actors attempting to penetrate systems. It mimics a real system to lure attackers while monitoring and recording their activities without risking production systems. The definition is formally recognized in NIST and widely used security frameworks.

A honeytrap refers to a social engineering technique using personal attraction to manipulate a human target, not a computer system-based trap.

A honeytoken is a decoy digital artifact such as a fake credential or file used to detect unauthorized access, not a full computer system.
