What is a canary trap used for?

• A. Canary trap
• B. Honeypot
• C. SPF
• D. A record

Answer: (A)

Canary traps are used to identify the source of information leaks. The idea is to give each potential leaker a subtly different version of a sensitive item, embedding a unique, harmless marker in each copy. If the information later appears outside authorized channels, the marker reveals exactly who received that particular version, pinpointing the leaker without exposing everyone. This relies on controlled dissemination and traceable identifiers to detect leakage. Honeypots are decoys to lure attackers for study, SPF relates to validating the origin of email, and A records map domain names to IP addresses in DNS. These do not describe the leak-tracing purpose of a canary trap.
