Answer:
Honeytoken
Explanation:
Honeytokens (aka honey traps or honeypots) may be described as bogus or dummy IT resources which are created or placed in a system or network for the sole purpose of attracting the attention of cyber-criminals and being attacked. These might be servers, applications, complete systems or datasets which are placed online (via the public internet, or a public-facing gateway to a private network), in order to attract cyber-attackers.
Honeytokens may be specifically defined as pieces of data which on the surface look attractive to potential attackers, but actually have no real value – at least, not to the attacker. For the owners of the tokens (i.e. the people who set the trap), they can be of great value, as they contain digital information which is monitored as an indicator of tampering or digital theft.
