CISA Releases Guidance on Cyber Decoy Strategies [ https://www.cisa.gov/res= ources-tools/resources/using-cyber-decoys-strengthen-detection-and-response= ?utm_source=3D&utm_medium=3DGovDelivery ] 09/16/2026 12:00 PM EDT=20


Today, the Cybersecurity and Infrastructure Security Agency (CISA) released=
Using Cyber Decoys to Strengthen Detection and Response. [ https://www.cis= a.gov/resources-tools/resources/using-cyber-decoys-strengthen-detection-and= -response?utm_source=3D&utm_medium=3DGovDelivery ] The guidance helps defen= sive teams across critical infrastructure organizations incorporate decoy c= apabilities into broader cyber defense planning to detect and disrupt malic= ious activity early in the intrusion lifecycle.

Many organizations struggle to detect adversaries who use legitimate creden= tials, native tools, and living off the land [ https://www.cisa.gov/resourc= es-tools/resources/identifying-and-mitigating-living-land-techniques ] tech= niques to conduct discovery, move laterally, and access data. Cyber decoys = are assets that appear to be legitimate systems, accounts, or data, but are=
designed to distract adversaries, detect their presence, or facilitate col= lection of cyber threat intelligence (CTI). For robust cyber defense planni= ng, organizations should incorporate cyber decoys within a Zero Trust [ htt= ps://www.cisa.gov/topics/cybersecurity-best-practices/zero-trust ] model th=
at assumes no user, device, application, or network segment is inherently t= rustworthy and requires continuous verification. Because cyber decoy capabi= lities operate under the expectation that an adversary may gain some level =
of access to the environment, they can help defenders detect post-compromis=
e behavior earlier, collect CTI, and reduce time to detection.

This guidance introduces cyber decoy concepts and explains how organization=
s can use the MITRE Engage=E2=84=A2 [ https://engage.mitre.org/starter-kit/=
] framework and MITRE ATT&CK=C2=AE [ https://attack.mitre.org/resources/ ]=
knowledge base to plan decoy operations around adversary tactics, techniqu= es, and procedures (TTPs), organizational risk, and existing security contr= ols, regardless of their cybersecurity maturity level.

Organizations can use the guidance to:


* Understand how cyber decoys complement Zero Trust [ https://www.cisa.go= v/topics/cybersecurity-best-practices/zero-trust ] principles.=20
* Start with lower-complexity techniques, such as tripwires and honeytoke= ns.=20
* Design decoys based on cyber threat information and likely adversary be= havior.=20
* Integrate decoy alerts with existing monitoring and incident response p= rocesses.=20
* Test and refine decoy operations through threat emulation, red teaming,=
or purple teaming.=20
