Future-Back Threat Modeling: A Foresight-Driven Security Framework
This addresses a fundamental weakness in cybersecurity for security leaders by shifting from reactive to proactive threat modeling, though it appears incremental as it builds on existing frameworks.
The paper tackles the problem of traditional threat modeling being reactive by introducing Future-Back Threat Modeling (FBTM), a predictive approach that starts with envisioned future threats to identify vulnerabilities in current defenses, aiming to enhance predictability of adversary behavior and inform decisions for more resilient security postures.
Traditional threat modeling remains reactive-focused on known TTPs and past incident data, while threat prediction and forecasting frameworks are often disconnected from operational or architectural artifacts. This creates a fundamental weakness: the most serious cyber threats often do not arise from what is known, but from what is assumed, overlooked, or not yet conceived, and frequently originate from the future, such as artificial intelligence, information warfare, and supply chain attacks, where adversaries continuously develop new exploits that can bypass defenses built on current knowledge. To address this mental gap, this paper introduces the theory and methodology of Future-Back Threat Modeling (FBTM). This predictive approach begins with envisioned future threat states and works backward to identify assumptions, gaps, blind spots, and vulnerabilities in the current defense architecture, providing a clearer and more accurate view of impending threats so that we can anticipate their emergence and shape the future we want through actions taken now. The proposed methodology further aims to reveal known unknowns and unknown unknowns, including tactics, techniques, and procedures that are emerging, anticipated, and plausible. This enhances the predictability of adversary behavior, particularly under future uncertainty, helping security leaders make informed decisions today that shape more resilient security postures for the future.
