What type of deception technology involves planting documents that appear to contain sensitive information?

Honeyfiles are a type of deception technology specifically designed to enhance security by misleading potential attackers. They involve creating fake documents that are crafted to look like they contain sensitive or valuable information. When an attacker accesses these honeyfiles, they think they have found something of importance, which not only distracts them but can also trigger alerts for cybersecurity teams.

The purpose of honeyfiles is to detect unauthorized access attempts, providing insight into the methods and intentions of attackers, and allowing organizations to respond proactively. By offering a bait that resembles real data, honeyfiles help to protect actual sensitive data and can deter or delay attackers by creating confusion.

Other options, while related to cybersecurity, serve different purposes; for instance, honeynets consist of a network of decoy systems designed to attract, trap, and analyze attacks, but do not specifically focus on individual documents. Firewall lures and decoy protocols do not pertain directly to the planting of seemingly sensitive information, making honeyfiles the answer that best fits the question.
