New CISA Guidance Helps Critical Infrastructure Detect, Observe and Impede Malicious Cyber Activity
CISA released guidance to help critical infrastructure operators deploy decoy systems that detect and disrupt cyber intrusions, improving defenses against sophisticated attacks.
The Cybersecurity and Infrastructure Security Agency (CISA) published new guidance titled *Using Cyber Decoys to Strengthen Detection and Response*, offering a step-by-step process for implementing decoy systems within critical infrastructure networks. The guide addresses challenges organizations face in detecting adversaries who leverage legitimate credentials and native tools to move undetected. By integrating decoys alongside Zero Trust models, defenders can identify malicious activity earlier and reduce dwell time.
CISA Acting Executive Assistant Director for Cybersecurity Chris Butera emphasized the value of cyber decoys in proactive defense, stating they make networks less hospitable to adversaries even when techniques like living-off-the-land are used. The guide aims to demystify decoy strategies for teams of all skill levels, providing actionable steps to enhance resilience against compromise.
To implement the guidance effectively, defenders need familiarity with the MITRE ATT&CK® Matrix and enterprise security controls. The guide leverages these frameworks to design decoy strategies that align with known adversary tactics, enabling more targeted detection and response efforts.
CISA, as the nation’s cyber defense agency, encourages critical infrastructure organizations to adopt the guide’s recommendations to bolster their cybersecurity posture. The agency provides additional resources on its website and social media channels for further support.
