CISA releases guidance on deploying cyber decoys for defenses

US Cybersecurity and Infrastructure Security Agency: The US Cybersecurity and Infrastructure Security Agency (CISA) is a federal agency under the Department of Homeland Security responsible for protecting critical infrastructure from cyber threats and providing cybersecurity guidance and resources to public and private sector organizations. In this development, CISA has released its first detailed guidance document on deploying cyber decoy systems to help critical infrastructure operators detect, observe, and disrupt malicious activity, including living-off-the-land techniques. The guidance emphasizes practical, incremental strategies that complement Zero Trust models and leverage frameworks like MITRE ATT&CK and MITRE Engage. Guidance Release: This is CISA's first comprehensive guide focused specifically on cyber decoy deployment processes for critical infrastructure defenders. Defense Integration: Cyber decoy strategies are positioned to support existing Zero Trust implementations by generating high-fidelity alerts and aiding post-compromise detection. Framework Alignment: The recommendations are structured around the MITRE Engage and ATT&CK frameworks to enable practical planning and refinement of decoy operations.
