A Method for Quantifying Human Risk and a Blueprint for LLM Integration

Abstract

This paper presents the Cybersecurity Psychology Framework (CPF), a novel methodology for quantifying human-centric vulnerabilities in security operations through systematic integration of established psychological constructs with operational security telemetry. While individual human factors-alert fatigue, compliance fatigue, cognitive overload, and risk perception biases-have been extensively studied in isolation, no framework provides end-to-end operationalization across the full spectrum of psychological vulnerabilities. We address this gap by: (1) defining specific, measurable algorithms that quantify key psychological states using standard SOC tooling (SIEM, ticketing systems, communication platforms); (2) proposing a lightweight, privacy-preserving LLM architecture based on Retrieval-Augmented Generation (RAG) and domain-specific fine-tuning to analyze structured and unstructured data for latent psychological risks; (3) detailing a rigorous mixed-methods validation strategy acknowledging the inherent difficulty of obtaining sensitive cybersecurity data. Our implementation of CPF indicators has been demonstrated in a proof-of-concept deployment using small language models achieving 0.92 F1-score on synthetic data. This work provides the theoretical and methodological foundation necessary for industry partnerships to conduct empirical validation with real operational data.
