FRICH-4 is the fourth part of the Triad Model of Cybersecurity, developed by the National Institute of Standards and Technology (NIST). FRICH-4 stands for "Furnish, Respond, Implement & Communicate" and provides a framework for organizations to enhance their security practices. It focuses on four key activities: furnishing the latest security practices, responding to threats and vulnerabilities, implementing solutions, and communicating security awareness. FRICH-4 emphasizes early detection of threats and vulnerabilities, addressing them in an effective and timely manner, and proactive communication about tactics to prevent security breaches. FRICH-4 explains how organizations can continuously improve their security posture through ongoing assessment and monitoring.
