Future-Back Threat Modeling: A Foresight-Driven Security Framework

TL;DR

Future-Back Threat Modeling (FBTM) is a proactive security framework that starts with envisioned future threats and works backward to identify vulnerabilities in current defenses, enhancing anticipation of emerging cyber threats.

Contribution

This paper introduces the FBTM methodology, a novel foresight-driven approach that shifts threat modeling from reactive to predictive by focusing on future threat scenarios.

Findings

Identifies gaps and blind spots in current security architectures.

Enhances predictability of adversary tactics under future uncertainty.

Supports informed decision-making for resilient security postures.

Abstract

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.
