CISA Publishes Guide On Using Decoys To Catch Intruders
The guide treats deception as a process rather than a product purchase, which reframes the buying decision for critical infrastructure operators and the small security teams that support them.

The US Cybersecurity and Infrastructure Security Agency published a guide on September 16 for using decoys to detect attackers who sign in with valid credentials. The guide covers honeypots, honeytokens, breadcrumbs, and tripwires, and recommends mapping MITRE ATT&CK techniques to place decoys where coverage is weakest. Fortinet describes FortiDeceptor, which deploys more than 100 decoys and lures, as fitting that framework.
The agency's guidance arrives with a specific problem attached: attackers who log in with valid credentials and work through tools that already exist in the environment can look like legitimate users, and signature-based controls may not flag that activity at all.
Decoys reverse the logic. Because they serve no business purpose, legitimate users have little reason to touch them, so any interaction becomes a signal worth investigating. CISA breaks the toolkit into honeypots, honeytokens, breadcrumbs, and tripwires, and advises organizations to reuse tools they already own before buying anything new.
