The U.S. Cybersecurity and Infrastructure Security Agency (CISA) releases guidance on using “cyber decoys” to strengthen detection and response within networks. The guidance describes decoys as a deception technique that helps organizations identify, observe, and disrupt malicious behavior, including activity that blends in with normal operations.
CISA frames cyber decoys as complementary to zero-trust security approaches. Across the outlets, the guidance is aimed particularly at critical infrastructure organizations, and it also emphasizes that the approach can be adopted by smaller security teams that may have fewer resources. The underlying rationale is that adversaries can use legitimate credentials and built-in administrative tools, along with “living-off-the-land” tactics, which can make intrusions harder to detect.
While SecurityWeek and Infosecurity Magazine focus on what decoys do—detect, observe, and block malicious activity—Help Net Security highlights the accessibility goal of the guidance, noting that deception has often been limited to well-resourced teams. All sources describe the same CISA publication and its intended use as a practical defensive measure for enterprise environments.
