CISA cyber decoy guidance for critical infrastructure detection and response
Defensive Guidance
Summary

Show ▼
CISA released Using Cyber Decoys to Strengthen Detection and Response, a new guide that helps critical infrastructure teams deploy realistic cyber decoys to spot and interrupt malicious activity inside their networks. The guidance focuses on intrusions that use legitimate credentials, native tools, and living off the land techniques, which are often difficult to detect. It positions decoys as a way to improve early detection, generate high-fidelity alerts, and reduce MTTD.

CISA releases cyber decoy guidance for critical infrastructure
Initial DisclosureCISA released Using Cyber Decoys to Strengthen Detection and Response, a guide for critical infrastructure owners and operators to deploy realistic cyber decoys and information assets in internal networks and high-value areas to detect, observe, and impede malicious activity. The guidance says decoys can help defenders identify adversaries earlier, gather intrusion information, allocate defensive resources more effectively, and reduce mean time to detection while complementing existing Zero Trust models.
